chlorpicrin

England received 900 tons of our chlorpicrin and 368 tons of American phosgene.

A violent reaction is set up and the chlorpicrin distils over, generally without the necessity for any external heating.

When pure, chlorpicrin is a colorless liquid which boils at a temperature approximately of 112° C.

With the exception of chlorine, chlorpicrin was the first war gas to be manufactured on a large scale in this country.

Chlorpicrin is made by the reaction between picric acid and chlorine.
