Process for producing polyfluoroalkyl esters of unsaturated carboxylic acids in fluorinated solvents: Process for producing polyfluoroalkyl esters of unsaturated carboxylic acids in fluorinated solvents. Sato, Katsuyuki; Kokin, Keisuke; Ikeda, Sunao; Urata, Kimihiko ( Unimatec Co., Ltd., Japan). U.S. Pat. Appl. Publ. US 2006025625 A1 2 Feb 2006, 4 pp. (English). (United States of America). CODEN: USXXCO. APPLICATION: US 2005-191398 28 Jul 2005.There are some reagents like 356-86-5 is used in this study. PRIORITY: JP 2004-223054 30 Jul 2004. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Section cross-reference(s): 45 Polyfluoroalkyl esters of unsatd. carboxylic acids are produced in high yield in a more simple reactor and with much more redn. in the waste than the conventional process based on esterification reaction by subjecting a polyfluoroalkanol Rf-R-OH (Rf = C1-6 polyfluoroalkyl group; R = C1-6 alkylene group) and an unsatd. carboxylic acid to dehydration reaction in a fluorine-contg. solvent in the presence of an acid catalyst and a polymn. inhibitor. Thus, 300 g of 2,2,3,3,3-pentafluoropropanol, 130 g if itaconic acid, 1 g hydroquinone, and 470 mL of R-225 were charged into a 1 L glass reactor and 385 g concd. sulfuric acid added dropwise. The reaction was stirred for 1 h at room temp. then heated to 45° for 20 h to yield 77% bis(2,2,3,3,3-pentafluoropropyl)itaconate.Except for chemicals metioned above, 356-86-5 is also used. ..
