Title: Improvements in or relating to methods of separating the isomers of polychlorocyclohexanes
IPC: C07C17/38
Filed: 1951-09-10
Abstract: The gamma or delta isomer of benzene hexachloride is separated from mixtures containing other isomers of benzene hexachloride and which may also contain other benzene polychlorides having more than six chlorine atoms in the molecule, by treating the mixture with a solvent, separating the undissolved substances from the solution obtained, which solution is so controlled that it contains less than 20 per cent by weight of dissolved isomers of hexachlorocyclohexane other than alpha and beta isomers and the isomer to be isolated, rapidly cooling the solution with agitation for not more than 10 hours to obtain crystallization of the desired gamma or delta isomer and separating the product before the crystallization ratio, i.e. the ratio of the weight of the deposited crystals of the desired isomer to the total weight of said isomer originally in solution, reaches 70 per cent. Preferred features include treating the benzene hexachloride mixture at a temperature T1 and effecting crystallization by cooling to a temperature T2, the difference T1-T2 being between 5 DEG  and 50 DEG  C., and the recovery of the mother liquor which is used again for treating a further quantity of the mixture of isomers.  The process may suitably be used for the extraction of a product rich in gamma isomer from benzene hexachloride obtained by the photo-chemical chlorination of benzene. The process is also used for the separation of delta isomers and for the separation of products containing benzene heptachloride.  The process is described with reference to diagrammatic flow sheets illustrating the separation of gamma and delta isomers from crude benzene hexachloride by successive crystallization cycles.  Detailed examples of the crystallization of benzene hexachloride isomers using as solvents carbon tetrachloride, methanol, petroleum ether, isobutyl alcohol, tetrachlorethane and ethanol, are given.  Specifications 573,693, 586,439 and 586,442, [all in Group IV], are referred to.

Title: Improvements in or relating to the preparation of solid polymers of alpha-olefins
Inventor: MERTES THOMAS SHANE
IPC: C08F10/00
Filed: 1960-06-22
Abstract: Solid polymers of alpha-olefins are made by polymerizing the olefin in the presence of a catalyst system of which all, or a component thereof, has been subjected, as a dispersion in an inert liquid, to ultrasonic waves of such an intensity that the particles are broken down into very fine particles, e.g. 0,1 to 5,0 microns in size.  By "ultrasonic waves" is meant the vibratory waves of a frequency above the limits of the human ear. The olefin may be ethylene, propylene, isobutylene, or 3-methylbutene-1.  The catalyst may consist of a halide of titanium, zirconium, hafnium, vanadium, niobium, molybdenum or tungsten, and a metal alkyl, metal hydride, metal borohydride, or alkyl metal halide.  The polymerization and dispersing medium generally consists of a saturated liquid hydrocarbon.  Specified catalyst components are titanium trichloride, titanium dichloride, titanium tribromide or triiodide, zirconium trifluoride, vanadium trichloride, chromium trichloride, aluminium triethyl, triisopropyl or triisobutyl, and the corresponding magnesium and zinc compounds, n-butyl lithium, methyl sodium, butyl sodium, lithium hydride, lithium aluminium hydride, sodium hydride, sodium borohydride, potassium borohydride, methyl, ethyl, or phenyl magnesium bromide, diethyl aluminium chloride, and ethyl aluminium dichloride.  The polymerization may be effected in a continuous manner.  The polymer is recovered from the polymerization medium by conventional techniques, e.g. alcohol, water, or acid treatments.
