(POLY)ALKYLENE GLYCOL DIALKYL ETHER PRODUCTION METHOD
PROBLEM TO BE SOLVED: To provide a (poly)alkylene glycol dialkyl ether production method that can produce (poly)alkylene glycol dialkyl ether at lower cost and in particular that can enhance the reaction conversion of PO-based (poly)propylene glycol dialkyl ether. SOLUTION: Provided is a (poly)alkylene glycol dialkyl ether production method characterized in reacting, in the presence of tertiary amine, (poly)alkylene glycol and alkyl halide.

Carbon-13 NMR chemical shifts of dimeric model compounds of poly(propylene oxide): A proof of existence of the (C-H)-O attraction
Conformational energies of poly(propylene oxide) (PPO) have been determined from 13C NMR chemical shifts of its six dimeric model compounds. The model compounds were prepared and fractionated by supercritical fluid chromatography into three com
