isobutyl acetate usage and synthesis

product description	isobutyl acetate, also known as n-propyl acetate, is the esterfication product between acetic acid and 2-butanol. it is a water-white liquid with flavor of soft fruit ester. it is slightly soluble in water, miscible with ethanol, ethyl ether as well as many other kinds of organic solvent including alcohol, ether and hydrocarbon. it can be mainly used as the diluent of nitro-lacquer and perchlorethylene paint and the solvents of nitrocellulose and lacquer as well as the substitution solvent of butyl acetate and methyl isobutyl ketone. it can also be used as a component of the flavoring agent. it can also be used as the diluent of plastic printing paste and the extraction agent in the pharmaceutical industry. sec-butyl acetate has excellent capability of dissolving many substances. it can be industrially applied as the solvent for manufacturing of nitrocellulose paint, acrylic paint, polyurethane paint, etc., these paints can also be used as an aircraft wing paint, artificial leather coatings and automotive coatings. its dissolving capability is similar as n-butyl acetate and isobutyl acetate. in the coating formulation, it can be widely adopted for substitution of n-butyl acetate and isobutyl acetate. in metallic paints, people can apply butyl acetate to dissolve the cellulose acetate butyrate to obtain 15% to 20% solution. the above information is edited by the chemicalbook of dai xiongfeng.
content analysis	it can be determined according to the method 1 in ester assay (ot-18). the amount of the sample for taking is 1g. the equivalency factor (e) for the calculation can be taken as 58.08. alternatively, people can apply non-polar column method via gas chromatography (gt-10-4) for the determination. the above information is edited by the chemicalbook of dai xiongfeng.
toxicity	ld50: 13400 mg / kg (rat, oral). gras (fema).
limited use	fema (mg / kg): soft drinks: 11; cold drink: 16; confectionery: 36; bakery: 35; pudding class: 170; gum: 860; coating: 5.5. take appropriate amount as limit (fda§172.515,2000).
the maximum allowable amount as food additives and maximum allowable residue limits
chemical properties	it is a water-white liquid with soft fruit ester flavor. it is miscible with a variety of organic solvents such as alcohols, ethers and hydrocarbons.
application	it can be used as organic solvent, the solvent of nitrocellulose and lacquer, extraction agent, dehydrating agents. it can also be applied to collodion, nitrocellulose, varnishes, leather, pharmaceuticals, plastics and perfume industry.
production method	it can be obtained via the esterfication between iso-butanol and acetic anhydride in the presence of sulfuric acid. mix the acetic anhydride and iso-butanol solution followed by adding drop wise of sulfuric acid. heat for reflux of 5-6 h after a bit cooling, wash the refluxed liquid with water for 2-3 times. use sodium carbonate for neutralizing with sodium carbonate, wash with water until neutralized, dry over calcium chloride with vacuum distillation in oil bath to derive the finished products.
category	flammable liquid
toxicity grading	low toxicity
acute toxicity	oral- rat ld50: 13400 mg / kg
data irritation	skin- rabbit 500 mg / 24 hours of moderate; eyes - rabbit 500 mg / 24 hours of moderate.
hazardous characteristics of explosive	it is explosive when being mixed with air.
flammability and hazard characteristics	it is flammable in case of fire, high temperature and oxidant flammable with burning releasing irritated smoke.
chemical properties	clear liquid
storage characteristics	treasury: ventilation, low-temperature and dry; store it separately from oxidants.
extinguishing agent	dry powder dry sand, carbon dioxide, foam, 1211 fire extinguishing agent.
professional standards	twa 7000 mg / m³; stel 875 mg / m.
general description	a clear colorless liquid with a fruity odor. flash point 64°f. less dense than water (6.2 lb / gal) and insoluble in water. vapors are heavier than air .
air & water reactions	highly flammable. insoluble in water.
reactivity profile	isobutyl acetate reacts exothermically with acids to give alcohols and other acids. may react sufficiently exothermically with strong oxidizing acids to ignite the reaction products. reactions with bases also generate heat. combination with strong reducing agents (alkali metals and hydrides) generates flammable hydrogen.
health hazard	vapors may irritate upper respiratory tract and cause nausea, vomiting, dizziness and loss of consciousness. liquid irritates eyes and may irritate skin.
fire hazard	highly flammable: will be easily ignited by heat, sparks or flames. vapors may form explosive mixtures with air. vapors may travel to source of ignition and flash back. most vapors are heavier than air. they will spread along ground and collect in low or confined areas (sewers, basements, tanks). vapor explosion hazard indoors, outdoors or in sewers. runoff to sewer may create fire or explosion hazard. containers may explode when heated. many liquids are lighter than water.
