Butyl alcohol (butanol) - a colorless, oily liquid with a characteristic odor of fusel oil ( very similira to "fake vodka"). Sparingly soluble in water.

There are four isomers:

1 - Primary or normal butyl alcohol (n-butanol) (1-butanol);

2 - isobutanol normal (normal secondary butyl alcohol) (2-methyl-1-propanol);

3 - sec-butyl alcohol (isobutyl alcohol) (2-butanol);

4 - tert-butyl alcohol (t-butanol), (trimethyl) (2-methyl-2-propanol).;

Dmitrievsky chemical plant offers purchasing of 1-Butanol at good prices. Purchasing of butanol (purchasing of butyl alcohol) is also possible.

The toxicity of butanol

Butanol has relatively low toxicity (LD50 of 2290-4360 mg / kg), but the highest among the lower alcohols. Ingestion produces an effect similar to the effect of the use of ethanol. Butanol is contained in small amounts in a variety of alcoholic beverages. Sometimes butanol is obtained from fluids used as surrogate alcoholic beverage.


Concentration of 0.01 % in the air do not affect the organism,  while 0.02 % causes an inflammation of the cornea.


Vapor concentrations higher than the recommended level can irritate eyes and respiratory tract, may cause headaches and dizziness, anesthesia and other effects on the central nervous system.

Contact with skin:

  • Low level of toxicity.
  • Frequent or prolonged contact may defat and dry the skin with subsequent irritation and dermatitis.

Eye contact:

  • Causes irritating and may injure eye tissue


Small amount of fluid trapped in the respiratory tract ingestion or vomiting may cause bronchopneumonia or pulmonary edema.

It's flammable. It's assigned to 3rd Class of flammable liquids with a flashpoint of less than 23 degrees C but less 61 degrees C.

Avoid open flames, sparks and smoke.

Vapor- air mixtures are explosive.

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20 °C by spraying,  sometimes even faster.

Substance is heavier than air and may travel along the ground; distant ignition is also possible.

The substance may form explosive peroxides in contact with strong oxidizers,  such as acetic acid, nitric acid, hydrogen peroxide.

Not only butanol, you can make purchasing of butyl acetate here.
