Description
Verfahren zur Herstellung von Kunstharzen durch Umwandlung von Acrolein Im Patent 733 099 ist ein Verfahren zur Herstellung von Kunstharzen beschrieben, welches darin besteht, daß man Acrolein mit Thioharnstoff in katalytisch wirksamen Mengen behandelt.Process for the production of synthetic resins by converting acrolein In the patent 733 099 a process for the production of synthetic resins is described, which consists in treating acrolein with thiourea in catalytically effective amounts.
Es wurde dort auch bereits angegeben, daß man die Herstellung beispielsweise in Gegenwart von Methyl- oder Äthylalkohol vornehmerl kann. It has also already been stated there that the preparation can be carried out, for example, in the presence of methyl or ethyl alcohol .
In weiterer Ausbildung des Verfahrens wurde gefunden, daß man Kunstharze aus Acrolein mit verbesserten Eigenschaften herstellen kann, wenn man bei der Durchführung der Verharzung gemäß Hauptpatent dem Reaktionsgut vor oder während der Verharzung organische hydroxylgruppenhaltigeVerbindungen mit Siedepunkten von über 8o° einverleibt.In a further development of the process it was found that one can use synthetic resins can be made from acrolein with improved properties if one is in the process of performing the resinification according to the main patent the reaction material before or during the resinification organic compounds containing hydroxyl groups with boiling points above 80 ° are incorporated.
Die durch die Einverleihung der erwäluiten Zusatzstoffe modifizierten Kunstharze aus Acrolein zeigen verbesserte Eigenschaften gegenüber den nicht modifizierten Kunstharzen, z. B. wirken die Zusätze etwa in den Mengen von zo bis 7o °/o des Harzes als Weichmachungsmittel.Those modified by the addition of the selected additives Synthetic resins made from acrolein show improved properties compared to the unmodified ones Synthetic resins, e.g. B. the additives act in amounts of about 10 to 70% of the resin as a plasticizer.
Als einzuverleibende Stoffe können beispielsweise folgende verwendet «erden: einwertige Alkohole, wie Isopropylalkohol, Butylalkohol, Isoamylalkohol, Benzylalkohol, Phenyläthylalkohol, mehrwertige Alkohole, wie Äthylenglykol, Butylenglykole, Diäthylenglykol (HOHZC-CH,O-CH2-CH@OH), Triäthylenglykol, ungesättigte Alkohole, «wie Allylalkohol, \Iethallylalkohol (z-\lctliviallylalkohol), Phenole, wie Phenol, m-Kresol, Hydrochinon, ferner Stoffe, die zugleich Alkohole und Ketone oder Ester sind.The following substances, for example, can be used as substances to be incorporated «Earth: monohydric alcohols such as isopropyl alcohol, butyl alcohol, isoamyl alcohol, Benzyl alcohol, phenylethyl alcohol, polyhydric alcohols such as ethylene glycol, butylene glycols, Diethylene glycol (HOHZC-CH, O-CH2-CH @ OH), triethylene glycol, unsaturated alcohols, «Such as allyl alcohol, \ Iethallyl alcohol (z- \ lctliviallyl alcohol), phenols, such as phenol, m-cresol, hydroquinone, and also substances that contain alcohols and ketones or esters at the same time are.
Besonders bei der Zusetzung ungesättigter Alkohole und verwandter
Phenole scheint sich ein chemischer Einbau in die Harzmoleküle zu vollziehen. Bei
Anwendung nicht allzu großer Mengen werden die Harze härter und zugleich weniger
spröde, also auffallend vorteilhaft verändert.
6. Frisch destilliertes reines Aerolein wird mit io0/, Hydrochinon und 20/, Solfoharnstoff versetzt. Nach 5 Minuten beginnt unter starker Erwärmung die Reaktion. Man erhält ein glasklares, schwach gelbstichiges Polymerisat.6. Freshly distilled pure aerolein is mixed with io0 /, hydroquinone and 20 /, solourea added. After 5 minutes begins under intense heating the reaction. A crystal-clear, slightly yellowish polymer is obtained.
Erhöht man die Konzentration des Hydrochinons, so erhält man noch härtere und dabei weniger spröde Polymerisate.If you increase the concentration of the hydroquinone, you still get harder and less brittle polymers.
7. Frisch destilliertes reines Aerolein wird mit 2o0/, Hydrochinon und -2% Sulfoharnstoff versetzt. Nach 5 Minuten beginnt unter sehr starker Erwärmung die Reaktion. Durch Kühlung wird sie verlangsamt. Es bildet sich ein glasklares, etwas dunkler gefärbtes Reaktionsprodukt. .7. Freshly distilled pure aerolein is made with 2o0 /, hydroquinone and -2% sulfourea added. After 5 minutes it starts under very strong warming the reaction. It is slowed down by cooling. A crystal clear, slightly darker colored reaction product. .
B. Frisch destilliertes reines Aerolein wird mit 2o0/, m-Kresol und 2% Sulfoharnstoff versetzt. Nach 24 Stunden hat sich eine ölige, vollkommen farblose Substanz gebildet, die nach weiteren 24 Stunden in eine harte farblose ''lasse übergeht.B. Freshly distilled pure aerolein is mixed with 2o0 /, m-cresol and 2% sulfourea added. After 24 hours it has become oily, completely colorless Substance formed, which after a further 24 hours turns into a hard, colorless layer.
Fügt man größere Mengen Alkohol oder Glykol zu, so erhält man gummiartige, klebrige Produkte, die sich als Zwischenschichten für Sicherheitsgläser verwenden lassen.If you add larger amounts of alcohol or glycol, you get rubbery, sticky products that can be used as intermediate layers for safety glasses permit.
9. Frisch destilliertes reines Aerolein wird mit 670/, Triäthylenglykol und 20/, Sulfoharnstoff versetzt, in eine Glaskammer (0,5 mm lichte Weite) gefüllt und bei Zimmertemperatur stehengelassen. Die Polymerisation beginnt nach wenigen Minuten unter starker Erwärmung, wobei zur Vermeidung von Blasenbildungen gekühlt werden muß. Die Zwischenschicht läßt man bei 4o bis 6o' zu Ende reagieren. Die Durchschlagsfestigkeit ist sehr gut.9. Freshly distilled pure aerolein is mixed with 670 /, triethylene glycol and 20 /, sulfourea added, filled into a glass chamber (0.5 mm clear width) and left to stand at room temperature. The polymerization begins after a few Minutes under intense heating, being cooled to avoid the formation of bubbles must become. The intermediate layer is allowed to react to the end at 40 to 6o '. The dielectric strength is very good.
