摘要

ABSTRACT OF THE INVENTIONLactams alone or in combination with terephthalicacid are prepared in a sequence of steps from the carbonylhalide reaction product of a cycloparaffin and phosgeneand ultimately, where desired, carbon monoxide and chlorine,by acylation of benzene or an alkyl-substituted benzenewith the carbonyl chloride derivative of the cycloparaffin;and reduction and nitrosation of the resulting ketone; or,nitrosation alone, in the event the benzene nucleus isalkyl-substituted, to yield the desired lactam and aromaticacid which latter compound may be oxidized to the desiredphthalic acid.I
