3,5-Dinitrobenzoyl chloride(CAS#99-33-2)
Nature
yellow crystals. Crystallization in benzene, flammable. Soluble in ether, can be water and alcohol decomposition, or in the humid air hydrolysis of dinitrobenzoic acid and hydrochloric acid, can be dissolved in non-hydroxy solvent without decomposition. Melting point 69.7 °c. Boiling Point (1. 6kPa) 196 ℃.
Preparation Method
benzoic acid is nitrated with mixed acid (nitric acid and sulfuric acid) to obtain 3, 5-nitrobenzoic acid, which is then acylated with thionyl chloride and chlorine, the reaction product was purified to obtain a product (HCl gas was discharged from the reaction and absorbed with water).
Use
an intermediate of vitamin D may also be used as a Disinfection preservative and reagent.
Safety
high toxicity, strong irritation to mucosa, skin and tissues. Microsomal sudden variation test-Salmonella typhimurium 1 × 10 -6 m01/dish. Production of hydrazide). Leakage should be prevented, and the operator should wear protective equipment.sealed in glass bottles, with wooden boxes. The flammable and toxic substances shall be stored and transported according to the regulations. Take care to prevent damage.
