摘要

: CONTINUOS PROCESS FOR THE ALKYLATION OF CH-ACID COMPOUNDS WITH ALKYL CARBONATES IN GAS-LIQUID PHASE TRANSFER CATALYSIS CONDITIONS A continuos process for the alylation 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 dialkylcarbonte, 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.
