SIMPLE ETHERS PRODUCTION METHOD Russian patent published in 2018 - IPC C07C41/09 C07C43/04 B01J37/00 B01J29/04 

FIELD: technological processes.

SUBSTANCE: present invention relates to the ethers preparation process, which can be used as the motor fuels additives, and also as the diesel fuels cetane-enhancing additives. Method consists in the C₆-C₉ secondary alcohols intermolecular dehydration in the presence of catalyst, a wide porous zeolite with a ratio of SiO₂/Al₂O₃=15–30, in the production of which by the sol-gel method as the structure forming component trimethyl-auryl ammonium bromide is used, with deposited by the impregnation method sulfated zirconium oxide, at a temperature of 110–230 °C, overpressure of 10–70 kPa, and during the synthesis, the resulting olefins and water continuous distillation is carried out, after the synthesis stage the reaction mass is subjected to rectification to isolate the target product.

EFFECT: proposed method enables to obtain an end product with high selectivity.
