Definitions
- the present invention relates to a continuous manufacturing process for dimethylaminoethyl acrylate:
- CH 3 H 2 C CH-CO-CH 2 -CH 2 -N (ADAME)
- CH 2 CH— C-OC 2 H 5 (AE) II O in the presence of at least one transesterification catalyst, the azeotropic mixture AE-ethanol being drawn off continuously during the reaction.
- the catalysts used are usually tetraalkyl titanates such as tetraethyl titanate, the latter being particularly solution DMAE as described- in the requested 'to' French Patent No. 2 811 986. Furthermore, the fact that this transesterification reaction involves an acrylic monomer, it must be stabilized.
- At least one polymerization inhibitor such as 2-orthoditertio-butylparacresol (BHT), phenothiazine (PTZ) and hydroquinone methyl ether (EMHQ).
- BHT 2-orthoditertio-butylparacresol
- PTZ phenothiazine
- EMHQ hydroquinone methyl ether
- ADAME by the transesterification described above is carried out in a perfectly stirred continuous reactor (see FR-A-2 777 561).
- the subject of the present invention is therefore a process for the continuous manufacture of dimethyla inoethyl acrylate by transesterification from dimethylaminoethanol and ethyl acrylate, in the presence of at least one transesterification catalyst and in the presence of at least one polymerization inhibitor, the azeotropic ethyl acrylate-ethanol mixture being drawn off continuously during the reaction, characterized in that the reaction is carried out by implementing the technology in a tubular piston reactor.
- the distillation column (C) is mounted above a stirred reactor (R), which is mounted on the path of the reagent mixture sent to the first tubular piston reactor (RI), the injection of the catalyst being performed downstream of the stirred reactor (R).
- R stirred reactor
- the reaction of the invention is preferably carried out under air bubbling and preferably with an ethyl acrylate / dimethylaminoethanol molar ratio of between 1.1 and 3.5, preferably between 1.7 and 2.2.
- An esterification catalyst is advantageously chosen from tetraalkyl titanates, in particular tetraethyl titanium.
- the catalyst is used in an amount of 5 x 10 ⁇ 4 to 5 x 10 ⁇ 2 mole per mole of dimethylaminoethanol, preferably in an amount of 5 x 10 ⁇ 3 to 2 x 10 ⁇ 2 mole per mole of dimethylaminoethanol.
- the tetraalkyl titanate is introduced in solution, in all proportions, in dimethylaminoethanol.
- polymerization inhibitors are chosen from phenothiazine
- PTZ tertiobutylcatechol
- BHT 2-orthoditertiobutyl paracresol
- the reaction is advantageously carried out at a boiler temperature (B) of between 90 and 135 ° C and under a pressure of between 800 mbar and atmospheric pressure.
- reaction of the invention is carried out with a residence time of 2 to 6 hours.
- DMAE dimethylaminoethanol [HO-CH 2 -CH 2 -N (CH 3 ) 2 ]
- ADAME dimethylaminoethyl acrylate
- PTZ phenothiazine (stabilizer)
- the samples were analyzed in GPC to determine the content of DMAE, ADAME and ethanol and calculate the yield in ADAME, the conversion of DMAE and the selectivity in ADAME. Since dimethylaminoethanol is the limiting reagent (faulty reagent), all calculations have been made from this reagent.
- n the number of moles.
- the installation shown comprises: a capacity (c) in which the reaction mixture AE / DMAE to be introduced is stored and which is placed on a balance (B); two positive displacement pumps e and g, following each of which is mounted a back pressure valve; a distillation column (C) of 10 theoretical plates, equipped with a reflux or condenser head; three jacketed piston tubular reactors
- C piston piston reactors (RI), (R2) and 15 (R3)); a temperature recorder; a mass flow controller-regulator (noted
- the flow rates given, as well as the temperatures, correspond to a residence time 25 of 3 hours at atmospheric pressure.
- a solution composed of AE and DMAE is prepared with an AE / DMAE molar ratio of 1.6, stabilized with 2000 ppm of PTZ, by successively introducing into a capacity (c) of 5 1: 30 - 1500 g of DMAE ( 99.8% purity);
- a catalytic solution containing 25% of catalyst and 75% of EA (mass ratio) is prepared in a medium the
- the vacuum pump and the refrigeration system are put into operation.
- the compressed air tap is opened slightly and a slight bubbling of dry air is introduced into the reactor (R) at the bottom of the column (C).
- the oil heaters of the reactors (R1, R2, R3) and of the stirred reactor (R) are put into service (T reactor oil R1, R2, R3: 138 ° C; T reactor oil R: 152 ° C).
- the pumps are then put into service, the flow rate of the reaction mixture pump being adjusted by the programmer (P) (152 g / h) and the flow rate of the return pump £ being adjusted manually using a burette so that the level in the reactor (R) remains constant at around 80% filling rate.
- the agitation is put into service as well as the catalyst introduction pump.
- Example 1 is reproduced, except that the parameters appearing in Table 1 are modified. The results obtained are also reported in Table 1.
