| Abstract: | The components of byproduct during the manufacturing process of S-epichlorohydnn were analyzed by GC-MS.
The results indicated that there were 1 ,3-dichloro-2-propanol, 3-chloro-l ,2-propanediol, glycide, 1-hydroxy-2-acetone. 2 ,3-dichloro-1-propanol and 2 ,3-dichloro-1-propanol acetate in the sample. It was found that the main hydrolysis byproducts are 1 ,3-dichloro-2-pro-panol and 3-chloro-l ,2-propanediol. |
