Butyronitrile - Introduction
N-butyronitrile (also known as butyronitrile) is an organic compound with the chemical formula C4H9CN. The following is an introduction to the nature, use, preparation and safety information of n-butyronitrile:
Nature:
-N-butyronitrile is a colorless liquid with a pungent odor.
-It can be mixed with water and soluble in many organic solvents.
-The boiling point of n-butyronitrile is 117-119 ℃, and the density is about 0.77g/cm³.
-N-butyronitrile is a volatile liquid with fire risk for fire or explosion.
Use:
-N-butyronitrile is an important raw material for the synthesis of organic compounds, widely used in pharmaceuticals, dyes, plastics, rubber, coatings and synthetic fibers and other industrial fields.
-It is also used as an ingredient in foaming agents, lubricants and cleaning agents.
Preparation Method:
-The preparation of n-butyronitrile can be achieved by the transesterification reaction of hydrocyanic acid and butanol. Specifically, hydrocyanic acid and butanol react under acidic conditions to produce n-butyronitrile, and the pure product is obtained by fractional distillation.
Safety Information:
-NBR is an irritating and toxic compound that may cause eye and skin irritation.
-Prolonged exposure to or inhalation of n-butyronitrile vapor may cause damage to the respiratory tract and nervous system.
-It is recommended to wear protective gloves, goggles and protective clothing when handling n-butyronitrile, and to ensure that the operation is carried out under well-ventilated conditions.
-N-butyronitrile in the storage and handling process need to pay attention to fire and explosion prevention measures, to avoid contact with the oxidant and strong acid.
