4,4'-Dichlorobenzophenone Chemical Properties,Uses,Production

Chemical Properties

faintly yellow crystalline powder

Uses

4,4'-Dichlorobenzophenone is used as pharmaceutical intermediates. It is an important raw material and intermediate used in Organic Synthesis, Pharmaceuticals, Agrochemicals and dyestuffs. Bisaminonitrile was polymerized with 4,4'-dichlorobenzophenone using NaH as base.

Application

4,4'-Dichlorobenzophenone can be used to synthesize polyether-polyketones, as well as reduce polymer costs. Furthermore, it is a metabolic product resulting from the degredation of DDT.

Preparation

4,4'-Dichlorobenzophenone is prepared by the acylation of chlorobenzene with 4-chlorobenzoyl chloride. The conversion is typically conducted in the presence of an aluminium chloride catalyst in a petroleum ether solvent.
ClC6H5C(O)Cl + C6H5Cl → (ClC6H4)2CO + HCl

General Description

4,4′-Dichlorobenzophenone (DBP) is a metabolite obtained when one strain of ectomycorrhizal fungi, Xerocomus chrysenteron, degrades 1,1,1-trichloro-2,2-bis(4-chlorophe-nyl) ethane (DDT).

Purification Methods

Recrystallise it from EtOH [Wagner et al. J Am Chem Soc 108 7727 1986]. The semicarbazone has m 192-193o (from H2O). [Beilstein 7 H 420, 7 I 228, 7 II 359, 7 III 2076, 7 IV 1376.]
