Abstract
The invention relates to the process for making glyoxylate hemiacetals comprising reacting an alcohol of the formula ROH where R is alkyl, or reacting a formate ester of the formula ##STR1## where R is alkyl, with CO under pressure in the presence of a basic initiator of the formula M.sup.+ (OR).sup.- where M is an alkali metal and R is alkyl, and in the presence of a complexing agent for M.sup.+ having O and/or N donor atoms capable of solvating M.sup.+ or in the presence of a basic initiator of the formula NR".sub.4.sup.+ (OR).sup.- where each R" is the same or a different alkyl or aralkyl and R is alkyl.
