  • Production process for hydroxyalkyl ester
    Patent number: 6465682
    Abstract: In a production process for a hydroxyalkyl ester, comprising the step of carrying out a reaction between a carboxylic acid and an alkylene in the presence of a catalyst, the present invention is to provide: a production process which can stop the reaction economically and sufficiently safely. In a production process which comprises the step of carrying out the reaction between a carboxylic acid and an alkylene in a reactor 1 in the presence of a catalyst so as to produce a hydroxyalkyl ester, the reaction is stopped by introducing a reaction terminating liquid 21 into the reactor 1, wherein the reaction terminating liquid comprises water in a ratio of not less than 50 weight %, and has a low temperature of −5 to 45° C.
    Type: Grant
