Abstract: The present invention refers to water-soluble anionic polymer dispersion and its manu¬ facturing process. To be more specific, it is about the producing method of water-soluble anionic polymer dispersion which is characterized by containing radical copolymer. The radical copolymer was created from salt solvent that contains anionic monomer, non-ionic monomer, ionic dispersant, radical polymerization initiator and, anionic surfactant and/ or non-ionic surfactant.

Abstract: A novel compound, 1-(2-(4-hydroxybenzoyl)ethanoyl)-2-piperidone is an N-acyllactam compound which shows an excellent effect of accelerating alcoholic fermentation. This novel compound is prepared by converting 2-(4-benzyloxybenzoyl)acetic acid to the corresponding acetyl chloride, coupling the chloride with 2-piperidone or an alkyl metal compound thereof and removing the benzyl group.
