PICRONITRIC ACID - Upstream Downstream Industry
PICRONITRIC ACID - Nature
Open Data Verified Data
white or light yellow needle-like crystals. Bitter, not easy to absorb moisture. Insoluble in cold water, soluble in hot water, soluble in benzene, hot chloroform and boiling alcohol, slightly soluble in ether and gasoline. It is prone to explosion when dry. It is a strong oxidant, and can react with combustible materials and reducing agents to cause combustion and explosion. Can corrode metals, and the resulting metal salts are extremely sensitive to shock or heat. When heated, exposed to open flame, high heat, or subjected to friction and shock, explosion can occur. Reactions with strong oxidants may occur. It can react with heavy metal powder to form metal salt, which increases sensitivity.

PICRONITRIC ACID - Preparation Method
Open Data Verified Data
A mixture of 2,4-= nitrochlorobenzene and 2,6-= nitrochlorobenzene was hydrolyzed with sodium hydroxide to give 2,4-= nitrophenol sodium and 2, A mixture of 6-nitrophenol sodium was acidified with sulfuric acid and then nitrated with a mixed acid of concentrated sulfuric acid and nitric acid. The product was suction-filtered and washed with water to obtain sodium dinitrophenolate.

| Coagulation fixative | picric acid penetrates slowly into the tissue, and can strongly contract the tissue. But can make protein. The nucleic acid and the like are precipitated, and excessive hardening is prevented, and the ability to improve the dyeing ability in the future is great. Usually rarely used alone, often mixed with other drugs. After fixation need to be washed with 50% or 70% alcohol. Features: weak penetration, easy to make the tissue contraction, easy to explosion. Note: generally washed with 50% or 70% alcohol. |
