Anwendungen & Verwendung
Verwenden
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.
Herstellung & Synthese
synthetische
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
