PROCESS FOR PRODUCING BETA-HYDROXY-GAMMA-BUTYROLACTONE DERIVATIVES AND BETA- (METH) ACRYLOYLOXY-GAMMA-BUTYROLACTONE DERIVATIVES |
| abstract |
A process for producing β-hydroxy-η-butyrolactone or β-methyl-β-hydroxy-η-butyrolactone, represented by general formula (1): (wherein R1 represents hydrogen or methyl), which comprises converting glycidol or 2-methyl-2,3-epoxypropanol into a cyanide, hydrolyzing the cyanide, and converting the hydrolyzate into a lactone. |
