1. Objective To study the mechanisms of acetone cyanohydrin intoxication.

2. This paper presents a method to determine acetone cyanohydrin in the air of workshop with spectrophotometry.

3. Objective:In order to know the toxicity of acetone cyanohydrin to erythrocyte membrane in vitro.

4. Azoisobutyronitrile formamide was prepared by oxidization of hydroazoisobutyronitrile formamide which was synthesized through the reaction of semicarbazide and acetone cyanohydrin .

5. Reasons for filter frequent block for the post - treatment of acetone cyanohydrin are analyzed.

6. Acetone is mainly used as solvent, and for production of acetone cyanohydrin, MMA and bisphenol A secondly.
