Fluorine-containing (meth)acrylic esters

Fluorine-containing (meth)acrylic esters. (Mitsubishi Rayon Co., Ltd., Japan). Jpn. Kokai Tokkyo Koho JP 59181239 A2 15 Oct 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: C07C069-653; C07C067-08. APPLICATION: JP 83-54511 30 Mar 1983. DOCUMENT TYPE: Patent CA Section: 35 (Chemistry of Synthetic High Polymers) Section cross-reference(s): 74 The esters are prepd. by the reaction of (CnH2n+1-mFm)CH2OH (n = 1-3; m = 1-2n + 1) with (meth)acrylic acid in the presence of concd. H2SO4 followed by distn. The esters esp. useful in manuf. of electron-beam resists and sheaths for plastic optical fibers are prepd. in high yield with little by-products. Thus, methacrylic acid [79-41-4], 2,2,2-trifluoroethanol [75-89-8], 95% H2SO4, and hydroquinone monomethyl ether were agitated, heated 5 h at 75°, and then distd. 7 h at 70-88°/40-160 torr to give a product which was washed with NaOH and then with H2O and distd. at 50°/100 torr to give 82.0% 2,2,2-trifluoroethyl methacrylate [422-05-9].

DOCUMENT TYPE: Journal CA Section: 46 (Surface Active Agents and Detergents) Surfactants such as CF3CF2CH2O(C2H4O)3H (I) [63693-17-4] and CF3CH2OCH2CH2OH [2358-54-5] were prepd. A mixt. of 10 g CF3CF2CH2OH [422-05-9], 11.9 g ethylene oxide [75-21-8], and 0.3 mL 50% aq. NaOH was heated at 80-5.degree. for 2 h to prep. 32.8% I. .
