Abstract: Lactams alone or in combination with terephthalic acid are prepared in a sequence of steps from the carbonyl halide reaction product of a cycloparaffin and phosgene and ultimately, where desired, carbon monoxide and chlorine, by acylation of benzene or an alkyl-substituted benzene with the carbonyl chloride derivative of the cycloparaffin; and reduction and nitrosation of the resulting ketone; or, nitrosation alone, in the event the benzene nucleus is alkyl-substituted, to yield the desired lactam and aromatic acid which latter compound may be oxidized to the desired phthalic acid.
