摘要: A method for producing esters of an alpha, beta-unsaturated carboxylic acid are disclosed, the method includes reacting a three or four carbon beta-hydroxyalkanoate composition or mixtures thereof with a mono-alcohol under heating conditions to form a reaction product and distilling the reaction product to recover a composition containing at least fifty percent by weight of the ester of the alpha, beta-unsaturated carboxylic acid.

摘要: Methods and systems for producing alkyl hydroxyalkanoate from hydroxy carboxylic acid recovery bottoms. The methods generally comprise the steps of obtaining a hydroxy carboxylic acid recovery bottom, adding a mono-alcohol to the hydroxy carboxylic acid recovery bottom to obtain a first mixture, heating the first mixture in the presence of a catalyst to form a reaction product, distilling the reaction product, and recovering an alkyl hydroxyalkanoate fraction.
