Product Name：isobutanol

Molecular format：C4H10O

CAS No：78-83-1

Product molecular structure：

Chemical Properties:

Isobutanol, also known as isopropyl alcohol, 2-methyl propanol is a colorless alcohol flammable liquid. Isobutanol is one of the main ingredients of fresh tea leaves, black tea and green tea to produce the wonderful aroma with the molecular weight of 74.12, boiling point of 107.66 ℃, relative density of 0.8016 (20/4 ℃), refractive index of 1.3959 and a flash point of 37 ℃. Isobutanol is fully dissolved in alcohol and ether, slightly soluble in water. Its vapor can form an explosive mixture with air; the explosion limit is 2.4% (volume). It can form addition compounds (CaCl2 • 3C4H10O) with calcium chloride. Isobutanol can be obtained by the distillation of the by-product of methanol and can also be derived from distillation of crude fusel oil. Using Industrial carbonyl cobalt as a catalyst, making propylene and carbon monoxide and hydrogen mixture react at 110~140 ° C, 2.0265 × 107~3.0397 × 107Pa to generate butyraldehyde and isobutyraldehyde, and then via catalytic hydrogenation, separation can obtain isobutanol. Isobutanol is used in the manufacture of petroleum additives, antioxidants, plasticizers, synthetic rubber, artificial musk, fruit oil and synthetic drugs and also used as solvents and chemical reagents.

Application:

(1) For analysis reagents, chromatography reagents, solvents and extraction agent.
(2) As raw materials for the organic synthesis, and also act as a superior solvent.
(3) Isobutanol is raw materials for organic synthesis. It mainly used in the synthesis of isobutyronitrile, an intermediate for diazinon.
(4) As raw materials of organic synthesis, isobutanol is used in the manufacture of petroleum additives, antioxidants, 2, 6-butylated hydroxytoluene, isobutyl acetate (paint solvents), plasticizers, synthetic rubber, artificial musk, fruit oil and synthetic drugs. It can also be used to purify strontium, barium and lithium salts and other chemical reagents and used as a superior solvent.
(5) Extraction solvent. Food flavors listed in GB 2760-96.
