  • Continuous process for the alkylation of CH-acid compounds with alkyl carbonates in gas-liquid phase transfer catalysis-conditions
    Patent number: 4894471
    Abstract: A continuous process for the alkylation of CH-acid compounds with dialkyl carbonates in gas-liquid phase transfer catalysis conditions is described, consisting of contacting a mixture of a CH-acid compound (arylacetonitrile or malonic diester) and of a dialkylcarbonate, optionally added with an inert carrier (constituted by a polar or aprotic polar liquid or by a gas), with a catalytic bed comprising alumina spheres carrying a base and a phase transfer catalyst.
