1-Butanol

N-butanol is a colorless and transparent liquid that emits a strong light flame when it burns. It has an odor similar to fusel oil, and its vapor is irritating and can cause coughing. 63% n-butanol and 37% water form a constant boiling liquid. It is miscible with ethanol, ether and many other organic solvents. It is obtained by fermentation of sugars or catalytic hydrogenation of n-butyraldehyde or crotonaldehyde. It has also been detected in the volatiles of foods such as cheese, melon and cooked rice.

1. Mainly used in the manufacture of n-butyl ester plasticizers of phthalic acid, aliphatic dibasic acids and phosphoric acid, which are widely used in various plastic and rubber products. It is also a raw material for the organic synthesis of butyraldehyde, butyric acid, butylamine, butyl lactate, etc.It serves as a dehydrating agent, demulsifier, extractant for oils, pharmaceuticals (such as antibiotics, hormones and vitamins) and fragrances, additive for alkyd resin coatings, etc.It can also be used as a solvent for organic dyes and printing inks, and as a dewaxing agent.As a solvent, it is used to separate potassium perchlorate and sodium perchlorate, as well as sodium chloride and lithium chloride.Used for washing sodium zinc uranyl acetate precipitates.Used in the colorimetric determination of arsenic acid by molybdate method.Determination of fat in milk.Medium for saponification of esters.Preparation of paraffin embedding materials for microscopic analysis.Solvent for fats, waxes, resins, shellac, gums, etc.Cosolvent for nitro lacquers, etc.

2. Standard substance for chromatographic analysis.Used for the colorimetric determination of arsenic acid and as a solvent for the separation of potassium, sodium, lithium and chlorates.

3. An important solvent, widely used in the production of urea-formaldehyde resins, cellulose resins, alkyd resins and coatings, and can also be used as a common non-reactive diluent in adhesives.It is also an important chemical raw material for the production of plasticizers such as dibutyl phthalate, aliphatic dibasic acid esters and phosphate esters.It is also used as a dehydrating agent, demulsifier, extractant for oils, fragrances, antibiotics, hormones, vitamins, etc., additive for alkyd resin coatings, cosolvent for nitro lacquers, etc.

4. Cosmetic solvent.Mainly used as a cosolvent in cosmetics such as nail polish, matching main solvents such as ethyl acetate to help dissolve colorants and adjust the evaporation rate and viscosity of the solvent.The addition amount is generally about 10%.

5. Can be used as a defoamer for ink preparation in screen printing.

6. Used in baked goods, puddings and candies.
