-124- A process for preparing S-124-butanetriol

摘要

The present invention is highly pure (S) -1,2,4- butanetricarboxylic relates to a method for producing the all, more particularly (S) -3- acetoxy-butyric -γ- using a lactone as a starting material and hydrogenating them to by removing a part reaction generated after the sodium borohydride reduction and then effectively to a method for producing (S) -1,2,4- butanetriol represented by the following formula (1) in high purity.
