chlorpicrin

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

A similar method was used for filling shell with chlorpicrin, except that refrigeration was unnecessary.

This plant was rated at 12½ tons of chlorpicrin a day, but reached a production as high as 31 tons on one day.

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