It was learned from Liaoyang Petrochemical Company that this company's “preparation method for the preparation of polypropylene with high chlorinated chlorinated polypropylene†obtained the invention patent authorization of the State Intellectual Property Office. At present, the isotacticity and crystallinity of polypropylene prepared by slurry method at home and abroad are relatively high, and the distribution of particles is not uniform and can not meet certain specific requirements. Since 2004, Liaoyang Petrochemical Organization has specialized in scientific research and successfully developed a new type of polypropylene preparation method. The polypropylene product produced by this method has a relatively high melt index, relatively low isotacticity, crystallinity, and good particle morphology. The degree of chlorination of chlorinated polypropylene produced by this method is greater than 60%. The patented method can realize industrial production in the existing slurry polypropylene plant , and is of great significance for Liaoyang Petrochemical to develop new polypropylene products and enhance market competitiveness. Dibenzoylmethane (DBM) is a chemical substance with a molecular formula of C15H12O2 and a molecular weight of 224.25. Dibenzoylmethane is used as a co-stabilizer in the calcium/zinc hydroxy acid salt stabilization system for the manufacture of PVC mineral water bottles. , an analytical reagent for the determination of carbon disulfide and thallium. Dibenzoylmethane is a colorless rhombic flaky crystal, easily soluble in chlorohydrin and chloroform, soluble in sodium hydroxide solution, insoluble in sodium carbonate solution, very slightly soluble in water.
