Abstract: Prepn. of aromatic ketones is by acylation of suitable aromatic cpds. with acid chlorides or anhydrides opt. under pressure, using as catalyst a mono- or bi-cyclic aromatic sulphonic acid carrying is not 2 NO2 pgs. and cpds. of formula (I): R1-C(O)-R2 (where R1 is aryl or aliphatic and R2 is aromatic or heterocyclic carrying 2-4 gps. 1, 2 or 3 of which are NO2. Nitrobenzophenones are inters for plasticisers and dyes.
