5. On some Derivatives from the Olefines

Abstract

This paper is supplementary to, and forms the sequel of, a series of papers which have been published in the “Quarterly Journal of the Chemical Society of London.”In continuing the examination of the behaviour of the olefines towards compound halogens, certain compounds previously described have been submitted to a test of homogeneity, of which the following is the principle:—“If a body be partly dissolved in a solvent, and if the dissolved part and the undissolved part, or the dissolved part and the whole, or the undissolved part and the whole, have the same composition, then the body is a simple one.”

Final report : multicomponent forensic signature development : interactions with common textiles; mustard precursors and simulants.

Veterans at risk: the health effects of mustard gas and Lewisite

“…An 1860product was identified as a compound [(C 2 H 4 ) 2 S 2 CI 2 1 different from sulfur mustard; however, the observed severe skin blistering, latent period of several hours, and subsequent slow healing are all typical of skin exposure to sulfur mustard. At about the same time, Guthrie (1859Guthrie ( , 1860 published investigations describing yet another variant compound (thought to be C 4 H 4 S 2 C1 2 ), also produced from sulfur chloride in reaction with ethylene. The odor was "pungent," resembling that of "oil of mustard."…”
