Chinese name: diethyl phthalate DEP English name: Diethyl phthalate CAS: 84-66-2 Formula: C12H14O4 Molecular Weight: 222.24 Physical and Chemical Indicators Project Industrial chemically pure analytical ester content,% ≥99.0 99.0 ~ 100.5 99.5 ~ 100.5 acidity ( C8H6O4),% ≤0.01 ≤0.01 ≤0.01 Moisture,% ≤0.10 ≤0.08 ≤0.05 color (platinum-cobalt color), No. ≤30 ≤25 ≤20 relative density (d420) 1.118 ~ 1.122 1.191 ~ 1.195 1.191 ~ 1.195 Refractive rate (n20D) 1.500 ~ 1.505 1.500 ~ 1.505 1.500 ~ 1.505 ash,% ≤0.01 ≤0.01 ≤0.01 thermal stability (platinum-cobalt color), No. - ≤50 ≤50 Flash Point, ℃ ≥130 ≥130 ≥130 Chemical Properties colorless transparent oily liquid, with slight aroma. With alcohol, ether, soluble in organic solvents such as acetone, benzene, insoluble in water. Use a diethyl phthalate DEP intermediates, the solvent is also important. Used plastic plasticizer. 2 reagents for the analysis, gas chromatography stationary phase, cellulose ester solvents, plasticizers and lubricants 3 as plasticizers, solvents, lubricants, fixative, colored or precious metals from mine flotation foaming agents, gas chromatography stationary phase, alcohol denaturant, insecticide spraying. The product with cellulose acetate, cellulose acetate butyrate, polymethyl methacrylate, polystyrene, polyvinyl butyral, vinyl chloride - vinyl acetate copolymer resin, etc. Most have good compatibility. Mainly cellulose resin as a plasticizer. 4 fixative agent used as a spice.
