Hemiacetals of glyoxylic acid esters and process for isolation of glyoxylic acid esters |
| abstract |
The invention relates to hemiacetals of glyoxylic acid esters and to a process for obtaining a glyoxylic acid ester having a C 1 -C 4 -ester group from a mixture which essentially contains such a glyoxylic acid ester and water and / or a C 4 -C 4 alcohol ROH. The glyoxylic acid ester and the water and / or the alcohol are partially or completely in chemically bound form. A higher alcohol R'OH with a boiling point above 180 ° C. is added and the water and / or the alcohol ROH and then the glyoxylic acid ester are distilled off at a pressure of at most 800 mbar. |
