METHOD OF SYNTHESIS OF ALKYLAROMATIC COMPOUNDS Russian patent published in 1998 - IPC

FIELD: organic chemistry. SUBSTANCE: alkylaromatic compounds were synthesized by alkylation of aromatic compounds with olefins and/or C₅-C₄₀-alcohols in the presence of alumosilicate containing 25% silicon oxide, not less, and 2-55 wt.-% zeolite phase that contains 50% rare-earth element oxides, not above. Reaction is carried out at 110-280 C under pressure 1-30 ata. The yield of alkylaromatic compounds is up to 90%. The synthesized compounds were used as high-temperature organic heat carriers. EFFECT: improved method of synthesis, increased yield.
