MF : C24H38O4 MW: 390.30 Properties: colorless oily liquid , specific gravity 0.9861 ( 20/20 ) , melting point -55 , boiling point 370 ( atmospheric pressure ) , insoluble in water , soluble in alcohol , ether , mineral oil, most organic solvents. Quality Index : GB11406-89 Table dioctyl phthalate Performance Indicators Project Excellent grade First grade Appearance transparent, no visible impurities oily liquid Dioctyl phthalate ( platinum - cobalt ) number ≤ 30 40 Ester content % ≥ 99.5 99 Density (p20) g / cm 3 0.982-0.988 0.982-0.988 acidity ( as phthalic acid )% ≤ 0.01 0.015 Loss on drying % ≤ 0.2 0.3 flash point ℃ ≥ 195 192 chroma after heat treatment ( platinum - cobalt ) number ≤ 100 - volume resistivity . cm ≥ 1x10 〃 - octyl phthalate plasticizer is important general , mainly for the processing of polyvinyl chloride resin , but also for synthetic resins, acetate resins, ABS resins and rubber processing of polymers , can also be used in making paints , dyes , dispersing agent. General Purpose DOP, widely used in plastics , rubber, paint and emulsifier and other industries . PVC plasticized with it can be used in manufacture of artificial leather , agricultural films, packaging materials , cables. Electrical grade DOP, all with a common grade DOP performance , but also has good electrical insulation properties , mainly for the production of wires and electricity. Grade DOP, mainly for the production of food packaging materials . Medical grade DOP, mainly for the production of health care products, such as disposable medical devices and medical packaging materials.
