Title: Process for the production of fluorinated carbonyl compounds
Inventor: MOORE EARL PHILLIP
IPC: C07C45/58
Filed: 1964-10-28
Abstract: Fluorinated carbonyl compounds are obtained by isomerizing a compound <FORM:1019788/C2/1> where Rf1, Rf2 and Rf3 are fluorine atoms or C1- 8 perfluoroalkyl or omega-hydroperfluoroalkyl radicals, or two together make up a C2- 8 perfluoroalkylene radical, by contact with a catalyst consisting of an acidic metal oxide, a chloride, bromide, iodide, oxychloride or oxybromide of a polyvalent metal having a valency less than its maximum co-ordination number, a transition metal carbonyl, a compound producing fluoride ions in the presence of the epoxide, a tertiary amine, a tertiary amine oxide or a tertiary amide. Depending on whether an acidic or a basic catalyst is used, the following type of reaction may occur: <FORM:1019788/C2/2> where the Rf radicals are C1- 8 perfluoroalkyl or omega-hydroperfluoroalkyl.  Specified catalysts are Al2O3, TiO2, WO2; AlCl3, AlBr3, SnCl4, VOCl3, TiCl4, FeCl3, CuCl2, ZrOCl2; tungsten carbonyl, iron carbonyl; KF, KHF2, C5F, PF5, SF4, BF3 etherate, alkali metal carbonates, alkali and alkaline earth metal hydroxides, reduced transition metal oxides; trimethylamine, triethylamine, dimethylaniline, pyridine; pyridine N-oxide, trimethylamine N-oxide; dimethylformamide, dimethylacetamide and diethylbenzamide. Solvents may be used.  In examples, hexafluoropropylene oxide gives hexafluoroacetone, with or without pentafluoropropionyl fluoride; perfluorocyclopentene oxide gives perfluorocyclopentanone; omega-hydro-perfluorohept-1-ene oxide gives H(CF2)6COF or H(CF2)5COCF3; tetrafluoroethylene oxide gives perfluoroacetyl fluoride; perfluoroisobutylene oxide gives perfluoroisobutyryl fluoride and (CF3)2CFCF2OC(CF3)2COF; and perfluorocyclohexene oxide gives perfluorocyclohexanone.  Perfluorocyclopentene and perfluorocyclohexene (from KF and hexafluorodichlorocyclopentene, or 1,2-dichloroperfluorocyclohex-1-ene or 1,2,4,4,5,5 - hexachloro - 3,3,6,6 - tetrafluorocyclohex-1-ene respectively, in the presence of N-methylpyrrolidone) are converted to the epoxides with methanolic alkaline H2O2, and unreacted olefin removed.

In examples, such polymer compositions comprise dispersions of: (1) poly (hexamethylene adipamide)/caprolactam copolymer in poly (ethylene glycol); (2) poly (ethylene terephthalate) in poly (ethylene glycol); (3) poly - caprolactam in poly (ethylene glycol); (4) N,N1-di-isobutyl hexamethylene diamine/caprolactam copolymer in polystyrene; (5) a polyester urethane (see Specification 1,040,365) in polystyrene or poly (ethylene glycol).ALSO:Fibrils for paper-making are obtained by disintegrating by mechanical means a fibrillatable structure made by forming a dispersion of one synthetic polymer on another, the dispersion medium polymer comprising 1-48% by weight of the total polymer weight, extruding the dispersion, and removing from the extrudate the dispersion medium polymer, which may be polylethylene glycol. "Extrusion" includes spinning through a nozzle, casting, spraying on to a surface or withdrawing from a reaction medium. The extrudate is not subjected to an extension of more than 25% of its length.  In Example 3, an aqueous slurry of poly (hexamethylene adipamide)/caprolactan copolymer fibrils is mixed with poly(hexamethylene adipamide) staple fibre and a hand sheet is formed therefrom.  The sheet is then heated under pressure between aluminium sheets to cause melting and bonding of the fibrils.  In Example 4, fibrils of poly (epsilon caprolactam) are similarly processed, and in Example 11, a waterleaf consisting entirely of poly (epsilon caprolactam) fibrils is made.

Title: Treatment of solutions of olefin polymers
IPC: C08C2/04
Filed: 1962-11-29
Abstract: Catalyst residues are removed from olefin polymers by dissolving the polymer in an inert organic solvent, treating the solution with a water-soluble monohydric alcohol containing dissolved therein an acid which yields water soluble reaction products with the catalyst residues, thereby forming a two-phase liquid system in which the inert organic solvent phase contains dissolved olefin polymer, and the alcohol phase contains catalyst residues, and washing the two-phase system with an agent consisting predominantly of water, e.g. steam plus a small proportion of ethylene diamine tetraacetic acid.  The polymer may be recovered from the organic solvent phase by conventional techniques.  The alcohol may be methanol or isopropanol. The acid is generally hydrochloric, hydrobromic, hydriodic, nitric, acetic, propionic, butyric, or benzoic.  The catalyst residues removed are of the Zeigler-type.  The polymers recovered, in the examples are poly-butadiene, and copolymers of ethylene and propylene.

[Also in Division E1] A face conveyer 2 of the scraper type discharges the coal on to a similar stage conveyer 1 disposed at substantially the same level and transverse thereto. The coal is transported along the lower runs 10, 23 of the conveyers 2, 1 and is transferred therebetween through an aperture 16 in the side wall of the trough of the stage conveyer 1, which aperture is substantially equal in length to the width of the face conveyer.
