Decanedioyl dichloride is the bis- carboxylic acid chloride of decanedioic acid ( sebacic acid ).
properties
Decanedioyl dichloride is a colorless liquid with a pungent odor and soluble in hydrocarbons and diethyl ether . Decanedioyl dichloride is corrosive; like all carboxylic acid chlorides , it hydrolyzes in water with the release of hydrogen chloride . However, it is less sensitive to hydrolysis than shorter-chain aliphatic carboxylic acid chlorides.
Decanedioyl dichloride has a flash point of 113 ° C.
Manufacturing
Decanedioyl dichloride can be prepared by reacting decanedioic acid in an excess of thionyl chloride . Remaining thionyl chloride can be removed by distillation after the reaction .
use
Decandioyldichlorid can with hexamethylene diamine to nylon 6,10 polycondensed be.
