effect:

Tetrachloroglycoluril is mainly used to prepare compound silkworm disinfectant. The compound disinfectant for silkworms includes two parts: the main agent tetrachloroglycoluril and the auxiliary agent ammonium bicarbonate. The weight percentage between them is: tetrachloroglycoluril: ammonium bicarbonate = 8 to 12%: 85 to 95 %. The main agent, tetrachloroglycoluril, is a chlorine disinfectant with the highest chlorine content in China. It was originally used in military environments, drinking water sources and swimming pools for disinfection and sterilization. Because of its low solubility in water (20°C, 55 mg/kg), However, it affected the practical effect and was gradually abandoned.

application:

Tetrachloroglycoluril can be used to prepare a flame retardant tetrakis (0-methyl-phenylphosphinic acid) glycoluril compound. The preparation method is: controlling the molar ratio of tetrachloroglycoluril and dimethyl phenylphosphinate. The ratio is 1:4~1:6. Add dimethyl phenylphosphinate dropwise into the organic solvent solution of tetrachloroglycoluril in four times, react at 80℃~100℃ for 5~7h, and then purify. , to obtain the product tetrakis (0-methyl-phenylphosphinic acid) glycoluril. The compound of the present invention is an excellent halogen-free phosphorus-nitrogen synergistic flame retardant and can be used for flame retardancy of polyester PBT, polyester PET, polyvinyl chloride, polyurethane, epoxy resin, unsaturated resin, etc. The process is simple and the equipment investment is low. , easy to realize industrial production.
