Patent ID: 7002024

Claim:
A process for preparing a cleaning composition, the process comprising the steps of: i) preparing N-cycloalkyl-2-lactam (IV) using a process comprising the step of contacting a lactone (I) with an aryl amine (II) in the presence of hydrogen gas and a metal catalyst, the metal catalyst being optionally supported, and, optionally, in the presence of a solvent; wherein: (a) n=0–11; (b) R 1 , R 2 , R 3 , R 4 , R 5 and R 6 taken independently are hydrogen, hydrocarbyl or substituted hydrocarbyl, C 1 to C 18 unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted cycloalkyl, unsubstituted or substituted cycloalkyl containing at least one heteroatom, unsubstituted or substituted aryl, or and unsubstituted or substituted heteroaryl; (c) R 7 is an aromatic group having from 6 to 30 carbons, and R 8 is a fully or partially reduced derivative of R 7 ; and ii) contacting N-cycloalkyl-2-lactam (IV) with a compound selected from the group consisting of anionic surfactants, nonionic surfactants, cationic surfactants, amphoteric surfactants, glycols, glycol ethers, aliphatic alcohols, alkanolamines, pyrrolidones, water, and mixtures thereof.
