How Is Chloropicrin Made?

In 1848, Scottish chemist J. Stenhouse prepared chloropicrin by treating picric acid

picric acid
It forms a colored complex that can be measured using spectroscopy. Picric acid forms red isopurpurate with hydrogen cyanide (HCN). By photometric measurement of the resulting dye picric acid can be used to quantify hydrogen cyanide. During the early 20th century, picric acid was used to measure blood glucose levels.

with sodium hypochlorite. ... Today, chloropicrin is manufactured by the reaction between nitromethane and sodium hypochlorite.

What is chloropicrin and how it is prepared?

Chloropicrin (Cl3CNO2), also called trichloronitromethane, toxic organic compound used alone or in combination with methyl bromide as a soil fumigant and fungicide. Chloropicrin has a boiling point of 112 °C (234 °F). ... Chloropicrin is typically prepared by chlorination of either picric acid or nitromethane.
