Title: Process of polymerisation and catalysts for use therein
IPC: C08F210/12
Filed: 1959-04-24
Abstract: The invention comprises aluminium chlorofluorides having a fluoride content of 9,7 to 72,8% by weight based on the total halogens present, the balance of the halogen being chloride, containing crystallites having radii of 500 Angstrom units or less.  Aluminium chlorofluorides mentioned have the empirical formulae AlCl2F, AlClF2, Al2Cl5F, Al2Cl3F3 and Al2ClF5.  The aluminium chlorofluorides are prepared by reacting stoichiometric proportions of anhydrous aluminium chloride dissolved in an inert solvent with hydrogen fluoride, boron trifluoride, benzotrifluoride or ethylidene fluoride, or by fusing mixtures of aluminium chloride and aluminium trifluoride.  In examples aluminium chlorofluorides are prepared by reacting aluminium chloride with boron trifluoride and with ethylidene fluoride, in ethyl chloride.ALSO:Olefinic or diolefinic hydrocarbons or halohydrocarbons are polymerized by contacting them with a catalyst comprising an aluminium chlorofluoride having a fluoride content of 9,7 to 72,8% by weight based on the total halogens present, the balance of the halogen being chloride, containing crystallites having radii of 500 Angstrom units or less. Aluminium chlorofluorides mentioned have the empirical formulae AlCl2F, AlClF2, Al2Cl5F, Al2Cl3F3 and Al2ClF5.  The monomers may be contacted with the aluminium chlorofluoride at -100 DEG C. to 250 DEG C. at atmospheric or superatmospheric pressure, with or without an inert diluent present.  One part by weight aluminium chlorofluoride may be mixed with 0,1 to 20 parts by weight of a co-catalyst, e.g. antimony pentachloride, antimony trichloride, tin tetrachloride, titanium tetrachloride, titanium trichloride, silicon tetrachloride, ferric chloride, aluminium bromide, chromium trichloride, zirconium tetrachloride and zinc chloride.  In examples aluminium chlorofluorides are used as catalysts, in some examples in conjunction with titanium tetrachloride, to form polymers of ethylene, cyclopentene, styrene, dicycloheptadiene, isobutylene and isoprene, and copolymers of isobutylene with isoprene, isobutylene with styrene, dicycloheptadiene with isoprene, and propylene with isoprene.  Other monomers mentioned are butene-1, pentene-1, hexene-1, heptene-1, octene-1, nonene-1, decene-1, dodecene-1, vinyl fluoride, chlorprene, methylstyrenes, ethylstyrenes, isopropylstyrenes, butylstyrenes, chloro-styrenes, chloromethylstyrenes and chloroisopropylstyrene.

Abstract: A continuous process for the production of substantially pure monosilane comprises (1) heating together in an invert or reducing gaseous atmosphere elementary Si and Mg so as to produce Mg2Si; (2) mixing the Mg2Si with NH4X (where X is a halogen, preferably Cl); (3) allowing reaction to occur in the presence of liquid NH3 and in the absence of air to produce SiH4; and (4) distilling the SiH4 gas.  The process may be effected in an entirely metallic apparatus comprising a reaction vessel containing a screw conveyer or being an inclined rotary kiln, an external furnace thereto, there being also provided exhaust means for removing air from the vessel and flushing means for introducing hydrogen or inert gas, an externally cooled heat-insulated reaction vessel for producing SiH4 equipped with an inlet for NH4X having means for exhausting air therefrom and for flushing with hydrogen or inert gas, means for washing the SiH4 with liquid NH3, a reflux cooler for the condensation of ammonia and associated therewith, a distillation apparatus. Subsequently, the silane may be thermally decomposed to yield highly pure silicon having B, P and As present as less than 1 part per billion.ALSO:Substantially pure monsilane prepared by reacting Mg2Si with NH4X (where X is a halogen) in the presence of liquid NH3 (see Division C1) is thermally decomposed and made in the form of a single crystal using the floating zone method.  By measurement of resistivity, the ratio of the boron to silicon content has been found to be less than 0,2 part per billion while the combined phosphorus and arsenic to silicon is below 0,5 part per billion.
