Isobutanol Use and Manufacturing

Methods of Manufacturing

The preparation method is based on syngas and propylene as raw materials, and isobutyraldehyde is obtained during the preparation of 2-ethylhexanol through oxo synthesis, and then isobutanol is obtained through hydrogenation.

Uses

Used as analytical reagent, chromatographic analysis reagent, solvent and extractant; used as a raw material for organic synthesis, and also used as a high-grade solvent; isobutanol is a raw material for organic synthesis and is mainly used as an intermediate for the synthesis of diazinon in pesticides Isobutyronitrile. Organic synthesis raw materials. Used in the manufacture of petroleum additives, antioxidants, 2,6-di-tert-butyl-p-cresol, isobutyl acetate (coating solvent), plasticizers, synthetic rubber, artificial musk, fruit essential oils and synthetic drugs. It can also be used to purify strontium, barium, lithium and other salt chemical reagents and as a high-grade solvent. Extraction solvent. GB2760-96 stipulates that it is allowed to use edible spices. Solvent. Extracting agent. Lithium chloride is extracted from the mixture of lithium chloride and sodium chloride or potassium, and strontium bromide and barium bromide are separated. Determination of calcium, strontium, barium, sodium, potassium, lithium, silver, chlorine and phosphite. Organic Synthesis.
