Introductions of Linear Alkyl Benzene Sulphonate:
O-phenylenediamine is also called 1,2-diaminobenzene and 1,2-phenylenediamine(CAS:95-54-5). From the water, the precipitate is white to light yellow leaf like crystal, and from chloroform, the precipitate is prismatic crystal. Exposed to the air, it is easy to change color, from white to yellow, brown to purple, and finally to black. The relative density is 1.2698. Melting point 103-104 ℃. The boiling point is 256-258 ℃. Slightly soluble in cold water (4.15 at 35 ℃), easily soluble in hot water (733 at 81 ℃), ethanol, ether, chloroform and benzene. It reacts with inorganic acid to form salt soluble in water, reacts with carbon disulfide to form 2-mercaptobenzimidazole, reacts with carbon dioxide under pressure to form benzimidazolone. This product is toxic. After inhalation, it will cause visual disturbance, contact with skin, cause inflammation, enter eyes and cause inflammation. The oral ld501070mg / kg of rats.
O-phenylenediamine is mainly used in the manufacture of pesticide bactericides (carbendazim, Benazolin, methyltobuzin, thiabendazole), reducing dyes (reducing yellow 6Gd, reducing brilliant orange GR), cationic dyes (cationic brilliant yellow 10ggf), polymer stabilizers (2-mercaptobenzimidazole), heterocyclic compounds (benzimidazole and quinoxaline), photosensitive materials, surfactants, antifreeze, copper corrosion inhibitor, etc. It is one of the components of hair dye formula, and it is also one of the commonly used organic reagents to identify 1,2-dione, carboxylic acid and aldehydes in analytical chemistry.
