Dimethyl phthlate

Another extremely important military characteristic is effectiveness against many different species of insects without the development of resistant strains. Every insecticide that must be added to the military list of supplies geometrically increases the difficulties of procurement and distribution. At the present time, nineteen different insecticides and insect repellents and four different rodenticides are issued by the Army Quartermaster. These figures do not include the different formulations of insect repellents issued under the same stock number. The three basic insect repellents are dimethyl phthlate, Indalone, and Rutgers 612. These repellents are issued either alone or in various combinations, further complicating the supply situation because of the variation in efficiency of these substances against different species of mosquitoes in different parts of the world.

Terephthalic acid (TPA) and dimethyl tere-phthlate (DMT) are precursors for polyethylene terephthalate, which in turn is used in the production of polyester fibers and film, PET bottles, and other polyester thermoplastic resins. In 1988 the total U.S. production was more than 7 billion lb. Current capacity is about evenly split between TPA and DMT. In the past, the relative ease of producing high-quality DMT gave it the largest share of the terephthalate market. The trend is now toward TPA, however, as the result of technological advances that permit better purification of TPA and the use of the acid directly in polymer formation.
