colorless liquid. Melting Point -96.2 °c. Boiling point 141.3 °c. Relative density 0.8014. Refractive index 3973. Flash point 40 °c. Insoluble in water, miscible with ethanol and ether. It can burn when exposed to open fire. Toxic.
prepared by the interaction of bromobutane with sodium cyanide. The sodium cyanide is heated and dissolved in a water bath, and then a certain amount of 95% industrial ethanol and bromobutane are added to reflux for 25-30 hours, cooled to normal temperature, and sodium bromide is filtered off, the filtrate was fractionated using a high efficiency fractionation column. Steam at 78-85 °c
The alcohol was removed, the 85-140 °c fraction was collected, and the fraction was treated with ammonium chloride to separate it into two layers, and the upper liquid was fractionated again, and the 138-141 °c fraction was collected as the finished product.
It is used as a raw material for organic synthesis and also for the extraction of benzene from mixtures of benzene and cyclohexane.
