    摘要： Dimethyl carbonate is obtained pure, from its solutions in methanol, by extractive distillation carried out with a temperature of from 60.degree. C. at the top to 250.degree. C. at the bottom of the column and employing, as the extractant, an aprotic organic liquid which is substantially inert toward dimethyl carbonate, boils at above 100.degree. C. at standard pressure, is miscible with dimethyl carbonate in all proportions and has a dielectric constant .epsilon. of from 4 to 90 and a dipole moment .mu. of from 1.5 to 5 Debye.

    摘要： Method of producing .gamma.-butyrolactams by reacting .gamma.-butyrolactones with ammonia in the presence or absence of water at elevated temperatures and pressures. The reaction is carried out continuously at temperatures ranging from 180.degree. to 340.degree.C whilst maintaining pressures which are at least 10 percent higher than the pressure equal to the sum of the partial pressures of the reactants at the temperature used. .gamma.-Butyrolactams are valuable intermediates, for example in the manufacture of polymers, pharmaceuticals and solvents.
