Properties and Chemistry
DDT is similar in structure to the insecticide methoxychlor and the acaricide dicofol. It is a highly hydrophobic, nearly insoluble in water but has a good solubility in most organic solvents, fats, and oils. DDT does not occur naturally, but is produced by the reaction of chloral (CCl3CHO) with chlorobenzene (C6H5Cl) in the presence of sulfuric acid, which acts as a catalyst. Trade names that DDT has been marketed under include Anofex (Geigy Chemical Corp.), Cezarex, Chlorophenothane, Clofenotane, Dicophane, Dinocide, Gesarol (Syngenta Crop.), Guesapon, Guesarol, Gyron (Ciba-Geigy Corp. - now Novartis), Ixodex, Neocid (Reckitt & Colman, Ltd), Neocidol (Ciba-Geigy Corp. - now Novartis), and Zerdane.

Famous quotes containing the words properties and/or chemistry:
“A drop of water has the properties of the sea, but cannot exhibit a storm. There is beauty of a concert, as well as of a flute; strength of a host, as well as of a hero.”
—Ralph Waldo Emerson (1803–1882)
“...some sort of false logic has crept into our schools, for the people whom I have seen doing housework or cooking know nothing of botany or chemistry, and the people who know botany and chemistry do not cook or sweep. The conclusion seems to be, if one knows chemistry she must not cook or do housework.”
—Ellen Henrietta Swallow Richards (1842–1911)
