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.
As an important solvent, N-butanol is widely used in the production of urea-formaldehyde resins, cellulose resins, alkyd resins and coatings. It can also be used as an inactive diluent commonly used in adhesives. It is also an important chemical raw material for the production of plasticizer dibutyl phthalate, aliphatic dibasic acid ester, and phosphate ester. It is also used as a dehydrating agent, anti-emulsifier, extractant for oils, spices, antibiotics, hormones, vitamins, etc., additive for alkyd resin coatings.

1. Mainly used as ester plasticizers to make phthalic acid, aliphatic dibasic acid and phosphoric acid.
2. A raw material for the production of butyraldehyde, butyric acid, butylamine and butyl lactate in organic synthesis.
3. A dehydrating agent, anti-emulsifier and extractant for oils, drugs (such as antibiotics, hormones and vitamins) and spices, and additives for alkyd resin coatings.
4. Used as a solvent and dewaxing agent for organic dyes and printing inks.
5. Used as a solvent to separate potassium perchlorate and sodium perchlorate, as well as sodium chloride and lithium chloride.
6. Used to wash the precipitate of sodium uranyl zinc acetate. In the colorimetric determination, the molybdate method is used to determine arsenic acid. Determination of fat in milk. Medium for saponification of esters. Preparation of paraffin embedding material for microscopic analysis. 7. Used as a solvent for fats, waxes, resins, shellac, gums, etc. Co-solvent for nitro spray paint, etc.
8 Chromatographic analysis of standard materials. Used for the colorimetric determination of arsenic acid, the solvent for separating potassium, sodium, lithium, and chlorate.
9 Cosmetic solvent. It is mainly used as a co-solvent in cosmetics such as nail polish, with the main solvent such as ethyl acetate, which helps to dissolve the color material and adjust the volatilization speed and viscosity of the solvent. The addition amount is generally about 10%.
10. It can be used as a defoamer for ink blending in silk screen printing.
11. Used for baking food, like puddings and candies.
