John Stenhouse FRS FRSE FIC FCS (21 October 1809 – 31 December 1880) was a British chemist. In 1854, he invented one of the first practical respirators . He was a co-founder of the Chemical Society in 1841.
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

In 1840, the Scottish chemist John Stenhouse found that the same chemical could be produced by distilling a wide variety of crop materials, including corn, oats, bran, and sawdust, with aqueous sulfuric acid; he also determined furfural's empirical formula (C 5 H 4 O 2). [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.
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 ]

Erythritol tetranitrate (ETN) is an explosive compound chemically similar to PETN, [1] though it is thought to be slightly more sensitive to friction and impact.. Like many nitrate esters, ETN acts as a vasodilator, and was the active ingredient in the original "sustained release" tablets, made under a process patent in the early 1950s, called "nitroglyn".
