1,4- dichlorobutane is an organic chemical compound consisting of the group of the chloroalkanes.

Production

1,4- dichlorobutane formed during the heating of tetrahydrofuran with hydrochloric acid (HCl). The cyclic ether is tetrahydrofuran (THF) is thereby transferred to a first substitution reaction in the aliphatic 4 - chlorobutanol.

This intermediate is reacted in a further substitution reaction of 1,4- dichlorobutane.

Properties

1,4- dichlorobutane is an inflammatory colorless liquid with an aromatic odor, which is sparingly soluble in water. It has a dynamic viscosity of 1.46 mPas at 20 ° C.

Use

1,4- dichlorobutane is a starting material for nylon synthesis.

Safety

The vapors of 1,4- dichlorobutane can form (52 ° C, ignition temperature 220 ​​° C flash point) with air to form an explosive mixture.
