| titleOfInvention | The method for producing acetic acid esters and ethylene glycol |
| abstract | The present invention relates to the co-productions of a kind of acetic acid esters and ethylene glycol, mainly solve existing acetic acid esters production technology generation water and form the technical problem that a variety of azeotropic mixtures cause process complexity, separating energy consumption high.Under the conditions of the present invention is by using existing for the catalyst, acetic acid is added in single reactive distillation column middle and upper part, C is added in lower part 1 ~C 5 Alcohol, ethylene oxide, acetic acid and alcohol occur esterification and generate acetic acid esters and water, ethylene oxide reacts coproduction ethylene glycol with the water that esterification generates, reaction distillation tower top obtains acetic acid esters, tower reactor obtains ethylene glycol, diethylene glycol, triethylene glycol and polyethylene glycol, the technical solution that the heavy constituents such as ethylene glycol product, diethylene glycol product, triethylene glycol product and polyethylene glycol are respectively obtained using rectifying, preferably solves the problems, such as this, can be used for the coproduction industrial production of acetic acid esters and ethylene glycol. |
