function | tetrachloroglycoluril is mainly used for the preparation of compound disinfectant for silkworm use. The compound disinfectant for silkworm, qiangloran, includes two parts: the main agent tetrachloroglycouride and the auxiliary agent ammonium bicarbonate, and the weight percentage between them is: tetrachloroglycouride: ammonium bicarbonate = 8 ~ 12%: 85 ~ 95%. The main agent of four chlorine glycoluril is currently the highest chlorine content of a chlorine Disinfection agent, originally used in military environment, drinking water sources and swimming pool Disinfection sterilization, because of its low solubility in water (20 ℃,55 mg/kg), and affect the practical effect, gradually abandoned. |
Application | tetrachloroglycoluril can be used to prepare a flame retardant tetrakis (0-methyl-phenylphosphinyl) the preparation method of the glycoluril compound is as follows: the molar ratio of tetrachlorglycoluril to phenylphosphinic acid dimethyl ester is controlled to be 1: 4~1: 6, the phenyl phosphinic acid Dimethyl Ester was added dropwise to the solution of four chlorine glycoluril in organic solvent, at 80 ℃ ~ 100 ℃, reaction 5~7H, after purification, the product tetrakis (O-methyl-phenylphosphinyl) glycoluril is obtained. The compound of the 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 and unsaturated resin, etc. The process is simple and the equipment investment is small, it is easy to realize industrial production. |
