METHOD OF SYNTHESIS OF DIETHYLENE GLYCOL DIALKYL ETHERS Russian patent published in 1997 - IPC

Abstract RU 2085553 C1

FIELD: chemical technology and organic chemistry. SUBSTANCE: product: diethylene glycol dialkyl ethers of the general formula (ROCH2CH2)O, where: R - alkyl-(C1-C4) were synthesized from diethylene glycol and the corresponding alkyl halogenides in ether medium. Process is carried in two-phase system: organic solvent - 50% aqueous solution of MeOH where: Me - Li, K, Na in the presence of quaternary ammonium salt of the formula R4N+X- where: R - alkyl-(C1-C12), benzyl; X - Cl, Br, J, OH, ClO at mole ratio diethylene glycol : alkyl halogenide : quaternary salt = 1:(2-3):(0.04-0.06), at 40-60 C. Method can be used for synthesis of catalyst for diene hydrocarbons polymerization and in synthetic rubber industry. EFFECT: simplified technology, increased yield of the end product. 1 tbl
