- 1 -Abstract:CONTINUOS PROCESS FOR THE ALKYLATION OF CH-ACID COMPOUNDSWITH ALKYL CARBONATES IN GAS-LIQUID PHASE TRANSFERCATALYSIS CONDITIONSA continuos process for the alylation of CH-acidcompounds with dialkyl carbonates in gas-liquid phasetransfer catalysis conditions is described, consisting ofcontacting a mixture of a CH-acid compound (arylacetoni-trile or malonic diester) and of a dialkylcarbonte, op-tionally added with an inert carrier (constituted by apolar or aprotic polar liquid or by a gas), with a cataly-tic bed comprising alumina spheres carrying a base and aphase transfer catalyst.
