white waxy crystals. The melting point was 54-56 °c. Boiling point 265~267 deg C. The relative density was 0.985. Refractive index 41734 (liquid). Flash point 110 °c. Soluble in acetone, chloroform and dioxane, slightly soluble in water, ethanol, ether, carbon disulfide and benzene. The reaction with hydrogen also gives the original butylene diamine.
acrylonitrile as raw material in alkaline conditions, and cyanuric acid reaction.
This product is mainly used as the raw material of quinacone pigment, which is widely used in automobile and galvanized iron coating, color printing pigment and colorant of plastic products. In addition, it is also a raw material for the production of nylon 4. It can also be used as a reagent.
This product is highly toxic and has a similar effect of cyanide. Oral LD50 450mg/kg on rats. The production workshop should be well ventilated and the equipment should be closed. The operator should wear protective gear. This product is generally packaged in a barrel, 180kg per barrel. Should be placed in a cool and ventilated place, according to the provisions of dangerous storage and transportation.

This kind of pigment is widely used in automobile and galvanized iron coating, color printing pigment and colorant for plastic products. It is also used to produce nylon -4 and pharmaceutical intermediates. It can also be used as a reagent. Used as a solvent for extracting aromatic hydrocarbons from petroleum fractions and a glazing agent for nickel plating, and also used in organic synthesis |
production method | using acrylonitrile as raw material and reacting with cyaneic acid under alkaline conditions. The yield is over 95%. The sodium cyanide aqueous solution can also be heated, the ethanol solution of 1, 2-dibromoethane can be added dropwise, and the reaction can be refluxed for 35 hours to generate succinonitrile. |
