    摘要: The present invention relates to a method for preparing S-HGB ((S)-3-hydroxy-γ-butyrolactone) using hydrolase, and more particularly to a method for preparing S-HGB in a high purity by hydrolyzing S-BBL ((S)-β-benzoyloxy-γ-butyrolactone) in the presence of hydrolase. According to the present invention, the S-HGB having an optical purity can be obtained in a high yield under simple process conditions without requiring reaction conditions of high pressure and high temperature or complex operating conditions by hydrolyzing S-BBL with hydrolase.

    摘要: The present invention relates to a stable microemulsion composition comprising metalaxyl-M(methyl N-(methoxyacetyl)N-(2,6-xylyl)-D-alaninate) used for agricultural fungicide as active ingredient. Specifically, the microemulsion composition of the present invention is characterized in that the phase is not destroyed at a wide range of temperature during storage to remain stable, even if the composition comprises a high concentration of active ingredient. Also, the microemulsion composition of the present invention can form stable microemulsion in a wide range of dilution concentration, even if the composition is diluted with water.
