A facile synthesis of hexa- and octaethylene glycols

A facile synthesis of hexa- and octaethylene glycols. Nakatsuji, Yohji; Kameda, Nobuko; Okahara, Mitsuo (Fac. Eng., Osaka Univ., Osaka 565, Japan). Synthesis, (3), 280-1 (English) 1987. CODEN: SYNTBF. ISSN: 0039-7881. 121-44-8 and 110-86-1 are also in the experiment. DOCUMENT TYPE: Journal CA Section: 45 (Industrial Organic Chemicals, Leather, Fats, and Waxes) Section cross-reference(s): 23 Triethylene glycol (I) [112-27-6] is converted to hexaethylene glycol [2615-15-8] in ￡80% yield on a preparative scale by monotosylation and condensing 1 mol of tosylate with 1 mol of I. Tetraethylene glycol [112-60-7] is similarly treated to give octaethylene glycol [5117-19-1]. Et3N [121-44-8] gave the best results as the tosylation catalyst, while NaOH was used for condensation. .
