Brief Introduction
Triphoto gas (BTC), namely, bis (Trichloromethyl) carbonate, is commonly known as solid phosgene, and the chemical formula is c3cl6o3. It is colorless crystal, has the smell of light gas, mainly used as a substitute for phosgene, and is used in medicine, pesticide and organic synthesis, and has better effect than liquid double light gas. The trioptical gas is prepared by the reaction of dimethyl carbonate and chlorine gas. Three light gas at 130 ° C is decomposed around, and the presence of impurities reduces the temperature. There will also be a small amount of decomposition during atmospheric distillation to generate phosgene and double phosgene (Trichloromethyl chloroformate). When chloride exists, the phosgene can produce phosgene safely and quantitatively, which solves the problem that phosgene can not be quantified in the reaction. Triphosgene can produce almost all reactions of phosgene, and can be used as reagents for chloroformylation, chlorination, carbonylation and some polymerization reactions. It can convert primary amine into isocyanate or substituted urea, carboxylic acid into acyl chloride, alcohol into carbonate or aldehyde (with dimethyl sulfate), aldehyde oxime and amide into nitrile, etc.

Brief Introduction
Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic electric jade), synthetic fiber (such as synthetic vinylon polyvinyl formal), leather industry, medicine, dyes, etc. Formalin has the ability of sterilization and antisepsis. It can soak biological samples. Its dilute solution (0.1-0.5%) can be used to soak seeds and disinfect seeds in agriculture. Catalytic oxidation is commonly used in industry to produce formaldehyde from methanol. Formaldehyde can react with silver ammonia solution to produce silver mirror, so that a thin layer of metallic silver as bright as a mirror is attached to the inner wall of the test tube (combined silver is reduced and formaldehyde is oxidized); It reacts with the newly prepared copper hydroxide suspension to form red precipitated cuprous oxide.
