Condensing a phenol and an acetoacetic acid ester |
| abstract |
When replacing the low molecular mercaptan used as a catalyst in the known process for preparing condensation products of phenols and acetoacetic acid esters by an n-alkyl mercaptan having of from 8 to 20 carbon atoms, the yield is improved and the reaction time reduced, while the working up of the reaction batch is simultaneously improved.n[US4022819A] |
