Description
Foreliggende oppfinnelse vedrører fremstilling av diesterdiamider egnet for syntese av vanlige polyesteramider. The present invention relates to the production of diester diamides suitable for the synthesis of ordinary polyester amides.
Polyesteramider er kjent innen polymerkjemien og har i makro-molekylet karakteristiske enheter både av typen Polyester amides are known in polymer chemistry and have in the macro-molecule characteristic units of both types
og av typen and of the type
Slike forbindelser fremstilles på mange måter,f.éks, ved å polymerisere blandinger av disyrer, dioler og aminer, eller å gå ut fra oksyéyrer og aminosyrer, eller ved hjelp av lignende reaksjoner. Ved anvendelse av de nevnte prosesser fremviser de oppnådde polyesteramider en struktur hvori enhetene (1) og (2) inngår på en uregelmessig- måte. Such compounds are produced in many ways, for example, by polymerizing mixtures of diacids, diols and amines, or starting from oxygens and amino acids, or by means of similar reactions. When using the aforementioned processes, the obtained polyester amides exhibit a structure in which the units (1) and (2) are included in an irregular manner.
En slik uregelmessig struktur har negativ innflytelse på de mekaniske egenskaper av de oppnådde produkter og deres egenskaper er videre vanskelig: å reprodusere. Such an irregular structure has a negative influence on the mechanical properties of the products obtained and their properties are furthermore difficult: to reproduce.
Flere metoder for oppnåelse av polyesteramider med regelmessig struktur har vært'foreslått og hvori enhetene (1) og (2) gjentas på en regelmessig og forut bestemt måte. Several methods for obtaining polyesteramides with a regular structure have been proposed in which the units (1) and (2) are repeated in a regular and predetermined manner.
De foreslåtte metoder baseres prinsipielt på den forutgående syntese av komplekse monomerer som f-.eks.- The proposed methods are based in principle on the previous synthesis of complex monomers such as
hvori R vanlig er hydrogen.eller et alkylradikal med et lavt karbonantall, som for eksempel metyl, R' er et toverdig radikal, fortrinnsvis p-fenylen, R" er et toverdig radikal av typen ^'CHg) in which R is usually hydrogen or an alkyl radical with a low carbon number, such as methyl, R' is a divalent radical, preferably p-phenylene, R" is a divalent radical of the type ^'CHg)
hvori n er et tall fra 2 til 10. where n is a number from 2 to 10.
For å fremstille slike komplekse monomerer har to prosesser til nå vært foreslått og representeres av følgende skjematiske fremstilling: To produce such complex monomers, two processes have so far been proposed and are represented by the following schematic representation:
Disse metoder har vesentlige praktiske' mangler. These methods have significant practical shortcomings.
Spesielt krever utførelsen av metode a) fremstilling av dyre mellomprodukter og en meget komplisert syntese. In particular, the execution of method a) requires the production of expensive intermediates and a very complicated synthesis.
På den annen side, ved å gå frem etter metode b), selv om denne er meget enkel fra ét teoretisk synspunkt, krever denne kritiske betingelser på grunn av at den må utføres ved dannelse av e± mellomproduktsalt med to kvaternære ammoniumgrupper, og en slik reaksjon er begrenset til noen få typer diaminer og særlig til dem med en aromatisk kjerne i molekylet. On the other hand, proceeding according to method b), although this is very simple from a theoretical point of view, it requires critical conditions due to the fact that it must be carried out by the formation of an e± intermediate salt with two quaternary ammonium groups, and such reaction is limited to a few types of diamines and especially to those with an aromatic nucleus in the molecule.
Fremstilling av diesterdiamider er en reaksjon som oftest medfører vanskeligheter. Når således et diamin omsettes med en diester hvori estergruppene er like er reaktiviteten av begge estergrupper den samme og isteder for et diesterdiamid oppnås blandinger av polymeriserte produkter, se f.eks. Kirk Othmer, Encyclopedia of Chemical Technology II utgave, bind 16, side 4. The production of diester diamides is a reaction that most often involves difficulties. Thus, when a diamine is reacted with a diester in which the ester groups are the same, the reactivity of both ester groups is the same and instead of a diester diamide, mixtures of polymerized products are obtained, see e.g. Kirk Othmer, Encyclopedia of Chemical Technology II Edition, Volume 16, Page 4.
Det har vært gjort forsøk på å eliminere fremstillingen av polymeriserte produkter ved å gå ut fra diestere hvori ester-gruppen har en forskjellig reaktivitet, som omhandlet i US.patentskrifter 3.322.757 og 3.252.977. Attempts have been made to eliminate the production of polymerized products by starting from diesters in which the ester group has a different reactivity, as discussed in US patents 3,322,757 and 3,252,977.
I henhold til de ovennevnte US.patentskrifter reagerer bare den mer reaktive estergruppe med diaminet for oppnåelse av diester-diamidene. According to the above-mentioned US patents, only the more reactive ester group reacts with the diamine to obtain the diester diamides.
Ulempen ved de fremgangsmåter som er omhandlet i de nevnte US.patentskrifter beror- i det forhold at det må fremstilles en blandet diester og fremstillingen av denne diester innbefattet mange trinn som beskrevet i beskrivelsene i de motholdte patentskrifter. The disadvantage of the methods discussed in the aforementioned US patents lies in the fact that a mixed diester must be prepared and the production of this diester included many steps as described in the descriptions in the opposed patents.
Ved den foreliggende oppfinnelse gjennomføres fremstillingen In the present invention, the preparation is carried out
av diesterdiamidet derimot ved -å gå ut fra en enkel diester som er lett tilgjengelig på markedet. of the diester diamide, on the other hand, by starting from a simple diester that is readily available on the market.
Reaksjonen, i: henhold til den foreliggende oppfinnelse-muliggjøres ved å -anvende et overskudd av diester.. The reaction, according to the present invention, is made possible by using an excess of diester.
Den foreliggende oppfinnelse tillater -fremstilling av diesterdiamider ved å gå ut fra en diester hvori de to estergrupper er identiske og derfor har samme reaktivitet, uten at det dannes annet enn meget små mengder polymeriserte produkter, til forskjell fra det som kunne forventes i henhold til teknikkens stand.' ■ The present invention allows the production of diester diamides by starting from a diester in which the two ester groups are identical and therefore have the same reactivity, without the formation of other than very small amounts of polymerized products, in contrast to what could be expected according to the technique stand.' ■
Det er nå overraskede blitt funnet en enkel og billig fremgangsmåte for fremstilling av de nevnte komplekse monomerer som kan anvendes for syntese av regelmessige polyesteramider og med en generell anvendelse. A simple and inexpensive method for the production of the aforementioned complex monomers has now surprisingly been found which can be used for the synthesis of regular polyester amides and with a general application.
Den foreliggende oppfinnelse vedrører således en fremgangsmåte for fremstilling av diesterdiamider med en generelle formel The present invention thus relates to a method for producing diester diamides with a general formula
hvori begge er R'" er like og er alkyl med 1 - 8 karbonatomer, A er en rettkjedet alkylgruppe med inntil 10 karbonatomer og B er en rettkjedet alkyl- eller dicykloalkylmetangruppe med inntil 16 karbonatomer, en dialkylencykloalkyl eller dialkylenfenylgruppe med inntil 12 karbonatomer eller en fenylenoksy-fenylengruppe, og det særegne ved fremgangsmåten i henhold til oppfinnelsen er at et diamin H2N-B-NH2, hvori B har den ovennevnte betydning omsettes med et overskudd av en dikarboksylsyre-diester med den generelle formel in which both R'" are the same and are alkyl of 1 - 8 carbon atoms, A is a straight-chain alkyl group of up to 10 carbon atoms and B is a straight-chain alkyl or dicycloalkylmethane group of up to 16 carbon atoms, a dialkylenecycloalkyl or dialkylenephenyl group of up to 12 carbon atoms or a phenyleneoxy-phenylene group, and the peculiarity of the method according to the invention is that a diamine H2N-B-NH2, in which B has the above meaning is reacted with an excess of a dicarboxylic acid diester with the general formula
hvori begge R"' er like og R"' og A har den ovennevnte betydning, idet omsetningen gjennomføres ved oppvarming av komponentene som sådanne, fortrinnsvis under en inert gassatmosfære, ved slikt trykk og sådan temperatur at den flytende fase i reaksjonssystemet bibeholdes. in which both R"' are equal and R"' and A have the above meaning, the reaction being carried out by heating the components as such, preferably under an inert gas atmosphere, at such a pressure and such a temperature that the liquid phase in the reaction system is maintained.
Temperaturen for denne fremstillingsreaksjon er ikke kritisk og velges fordelaktig i området fra 20 til 250°C med hensyn til de anvendte arbeidsbetingelser. Foretrukket gjennomføres en destillasjon under reaksjonen for å fjerne alkoholen. The temperature for this manufacturing reaction is not critical and is advantageously chosen in the range from 20 to 250°C with regard to the working conditions used. A distillation is preferably carried out during the reaction to remove the alcohol.
Som nevnt anvendes et overskudd av diester, med fordel fra 1,5 til 5 deler i forhold til en støkiometrisk del. As mentioned, an excess of diester is used, advantageously from 1.5 to 5 parts in relation to a stoichiometric part.
Reaksjonen utføres vanlig ved atmosfæretrykk og fordelaktig under en strøm av inert gass. Den kan også gjennomføres ved redusert trykk. Omsetningen gjennomføres fordelaktig i nærvær av organiske løsningsmidler i form av en blanding av en lavere alifatisk alkohol og et aromatisk hydrokarbon. The reaction is usually carried out at atmospheric pressure and advantageously under a flow of inert gas. It can also be carried out at reduced pressure. The reaction is advantageously carried out in the presence of organic solvents in the form of a mixture of a lower aliphatic alcohol and an aromatic hydrocarbon.
Selv om omsetningen foregår uten anvendelse av katalysator, kan forbindelser som vanlig fremmer transforestringsreaksjoner anvendes. Although the reaction takes place without the use of a catalyst, compounds which usually promote transesterification reactions can be used.
