1-Phenyl-2,5,8,11,14,17,20,23,26,29-decaoxatriacontane → Nonaethylene Glycol Monomethyl Ether

Participants

Reaction Steps

A solution of nonaethylene glycol benzyl methyl ether from above (38 g) in methanol (200 ml) was shaken with 10% palladium on activated charcal (Aldrich, 1.0 g) under hydrogen 344.7 kPa (50 psi) on a Parr apparatus overnight. The catalyst was filtered off (Celite™), and the filtrate was concentrated in vacuo to provide nonaethylene glycol monomethyl ether as an oil (23 g, 74%), 1H-NMR (CDCl3) δ: 3.67-3.47 (m, 36, 18 OCH2), 3.32 (s, 3, CH3).
