We are engaged in developing and producing the products of Gamma-butyrolactone series.

We produce pharmaceutical intermediates and fine chemicals of pyrrolidone with Gamma-butyrolactone as the main raw materials, and produce ramification intermediates of cyclopropyl and cyclopropane with 2-acetyl-Gamma-butyrolactone as the main material. This series of products mainly include: gamma- butyrolactone, 2-acetyl-gamma-butyrolactone, 5-chloro-2-pentanone, 2-pyrrolidone, N-methyl-2-pyrrolidone, cyclopropyl methyl ketone, dicyclopropyl ketone, cyclopropanecarboxylic acid, methyl cyclopropanecarboxylate, cyclopropanecarbonyl chloride, cyclopropyl carbinol, cyclopropyl methyl chloride, cyclopropyl cyanide, 2-amino-5-diethylamino pentane and so forth.
