摘要：
The invention relates to the use of one or more N-substituted 2-pyrrolidone-4-carbonic acid esters of formula (1), where R1 and R2 independently represent linear, branched, or cyclic C1-C6 alkyl, as (a) solvent(s). Said compounds can be used as solvents in industrial applications, e.g. for the production of varnishes and paints, in chemical syntheses, for cleaning or degreasing, in petrochemical processes, in the electronics and photovoltaic industries, or in pesticide preparations, for example.
