説明DDD, 1,1-dichloro-2,2-bis-(4-chlorophenyl) ethane, also known as TDE, is a metabolite of DDT, which found use in agriculture. As with DDT, the p,p -isomer is insecticidal and the o,p -isomer is an impurity.
使用For determination of protein-bound sulfhydryl groups.
純化方法It crystallises as leaflets from AcOH and is slightly soluble in EtOH, and AcOH, but is soluble in *C6H6 and in alkalis to give a yellow solution. [Zincke & Dereser Chem Ber 51 352 1918.] The acetoxy derivative has m 198-200o (from AcOH or dioxane/MeOH), and the diacetyl derivative has m 167-168o (from AcOH). A small amount of impure disulfide can be purified by dissolving it in a small volume of Me2CO and adding a large volume of toluene, filter rapidly and concentrate to one-third of its volume. The hot toluene solution is filtered rapidly from any tarry residue, and crystals separate on cooling. Recrystallisation from hot acetic acid gives crystals with m 220-223o [Barrett & Seligman Science 116 323 1952]. [Beilstein 6 I 481.]
