Inventors in Europe included John Stenhouse, a Scottish chemist, who investigated the power of charcoal in its various forms, to capture and hold large volumes of gas. He built one of the first respirators able to remove toxic gases from the air, paving the way for activated charcoal to become the most widely used filter for respirators. [ 8 ]
Lead styphnate (or, as it was then called, trinitro-orcinate) was discovered along with many other thrinitroresorcinate salts by British chemist John Stenhouse in 1871, the synthesis route involving action of trinitroresorcinol on lead acetate.
Chloropicrin was discovered in 1848 by Scottish chemist John Stenhouse. He prepared it by the reaction of sodium hypochlorite with picric acid : HOC 6 H 2 (NO 2 ) 3 + 11 NaOCl → 3 Cl 3 CNO 2 + 3 Na 2 CO 3 + 3 NaOH + 2 NaCl
