Abstract
A method for preparing glycolic acid through hydrolysis of alkoxyacetate is provided. The method includes: subjecting raw materials including the alkoxyacetate and water to a reaction in the presence of an acidic molecular sieve catalyst to produce the glycolic acid, where the alkoxyacetate is at least one selected from the group consisting of compounds with a structural formula shown in formula I; and in formula I, Rand Reach are independently any one selected from the group consisting of C-Calkyl groups. The glycolic acid production method in the present application can be implemented by a traditional fixed-bed reactor under an atmospheric pressure, which is very suitable for continuous production.
