2,2'-Azobisisoheptonitrile - Nature
Open Data Verified Data
colorless or white rhomboid crystals. Flammable and explosive. There are two isomers, cis and trans, whose melting points are 55.5-57 °c and 74-76 °c, respectively. Insoluble in water, soluble in alcohol, ether and dimethyl formamide and other organic solvents. In the presence of heat and light, nitrogen is released by decomposition, and a cyanide-containing radical is generated simultaneously.

2,2'-Azobisisoheptonitrile - Hair-making
Open Data Verified Data
The reaction between methyl isobutyl ketone and hydrazine hydrate was carried out at reflux temperature. After completion of the reaction, the reaction mixture was allowed to stand and further distilled to obtain hexanone and hydrazine. The reaction of hexanone-connected ammonia with hydrogen cyanide (obtained by reacting an aqueous solution of sodium cyanide with 70% Sulfuric acid) is carried out at 30 to 40 ° C. To form diisoheptanenitrile hydrazine. Diisoheptonitrile hydrazine was further subjected to chlorination reaction with chlorine at 10 ° C. Or lower to obtain a crude azobisisoheptanitrile. The crude azodiisoheptanitrile is dissolved in ethanol and then cooled to below 0 °c for crystallization to obtain the finished product.
