Process for preparing glyoxylic acid esters |
| abstract |
The invention relates to a method for producing glyoxylic acid esters from glyoxylic acid ester hemiacetals which a) are directly transesterified with an alcohol in the presence of a catalyst; or b) are firstly converted into the corresponding glyoxylic acid whole acetals and are then transesterified with an alcohol in the presence of a catalyst, whereupon after a) and b) the acetals are divided into the desired, free glyoxylic acid ester or the hydrate thereof. |
