BrCHi CHjBr. A colourless liquid with a sweet odour, m.p. 10°C, b.p. 132°C. Manufactured by passing ethene through bromine or bromine and water at about 20 C. Chemical properties similar to those of 1,2-dichloroethane when heated with alkali hydroxides, vinyl bromide is formed. Used extensively in petrols to combine with the lead formed by the decomposition of lead tetraethyl, as a fumigant for stored products and as a nematocide. 

T. Cairns and J. Sherma, eds.. Comprehensive Analytical Profiles of Important Pesticides, CRC Press, Boca Raton, Fla., 1992, 304 pp. From the series ModemMethods for Pesticide Analysis, provides detailed information on properties and analytical methodology for nine prominent pesticides, pyrethroids, and fumigants in food. Includes formulations and uses, chemical and physical properties, toxicity data, and tolerances on various foods and feeds. Analytical information may be given in enough detail for methods to be carried out without having to consult additional Hterature sources. 

Isobutjiene—isoprene elastomer (Butyl) has high resistance to oxidation, resists chemical attack, and is the elastomer most impervious to air. Because of these properties it is often used for protective garments, inflated air stmctures, cold air balloons, and fumigation covers.

Chemical disinfectants are limited in their use as air sterilants because of their irritant properties when sprayed. However, some success has been achieved with atomized propylene glycol at a concentration of 0.05-0.5 mgH and quaternary ammonium compounds (QACs) at 0.075% m be used. For areas which can be effectively sealed off for fumigation purposes, formaldehyde gas at a concentration of 1-2 mg H of air at a relative humidity of 80-90% is effective.
