Quality Standards:content: 98.5%; S: 1ppm Property and Purpose: diisobutyl phthalate is slightly soluble in water, and soluble in cellulose acetate, cellulose acetate butyrate, cellulose nitrate, ethyl cellulose, polyvinyl chloride, polyvinyl acetate, polyvinyl butyral polystyrene and other resins, mainly used as plasticizers.

Product Name:Aviation Gasoline Quality Standards: MON: 102.3 mon; content of tetraethyl lead: 0.93 g/kg; freezing point: <-70℃ Property and Purpose: "Guolian No. 1 (GL-1)" 100LL aviation gasoline refers to the gasoline of the specific property of supplying power for an aircraft by filling it to the reciprocating spark-ignition engine. The aviation gasoline of this specific property is the expected considering the performances of the aircraft engine itself, but is also limited by the specific property. The specificality mainly refers to the following four areas: evaporation, antiknock property, stability and low temperature resistance.

Product Name:Maleic Anhydride Quality Standards:mass fraction of maleic anhydride: 99.72%; fusion colority: 15Hazen; crystallization point: 52.7℃ Property and Purpose:maleic anhydride (MA) is the abbreviation of maleic anhydride; mainly used for producing unsaturated polyester resin (UPR) and alkyd resin. In addition, maleic anhydride is used as raw material to produce 1,4-butanediol (BOD), γ-butyrolactone (GBL), tetrahydrofuran (THF), maleic acid, fumaric acid, tetrahydrophthalic anhydride and other fine chemical products with a wide application range, and is widely used in the fields of pesticides, pharmaceuticals, paints, printing inks, lubricant additives, paper chemicals, textile finishing agents, food additives, surface active agents and other fields.

Quality Standards: n-butane content above 99% Property and Purpose:N-butane can be directly used as fuel or solvent, refrigerant and raw materials of organic synthesis. Furthermore, butane can be used as motor fuel mixture to control the volatile components, or as de-asphalting agent in heavy oil refining, wax precipitating agent in oil wells, spillover agent for secondary oil recovery, resin foaming agent, refrigerant in converting sea water to fresh water, olefin diluent, polymerization solvent and so on. Mixed with propane to produce LPG extensively used for household heating, cooking and industrial heating; and also extensively used as raw materials of organic synthesis. For example, producing butene and butadiene by dehydrogenation; producing isobutane by isomerization; producing maleic anhydride, acetic acid, acetaldehyde, etc. by catalytic oxidation; producing halogenated butane by halogenation; producing nitrobutane by nitrification; producing carbon disulfide by catalysis at high temperature; and producing hydrogen by steam reforming. Used for organic synthesis and production of ethylene, used as a raw material of synthetic rubber and high octane liquid fuel, or as domestic fuel, solvent, refrigerant, or used for instrument calibration.

Quality Standards:relative density (relative to water, at 20℃): 690 to 700 kg/m3; distillation range: 30 to 205, benzene: 0; sulfur content: not more than 10ppm; octane value: not less than 94; methanol: 0; not containing olefin and arene; passing Dr. experiment; copper corrosion: Grade 1. Property and Purpose: soluble in benzene, toluene, xylene, chloroform, diethyl ether, carbon disulfide, carbon tetrachloride, dimethylformamide and oils excluding degradable castor oil; slightly soluble in ethanol; practically insoluble in water; flammable, irritating and volatile, organically synthetic; solvent; to test the octane value of fuel oil by mixing with n-heptane; gas chromatography analysis meeting the standards; diluent.
