Title: Improvements in or relating to purification of benzene hexachloride
Inventor: BISSINGER WILLIAM ELLIS
IPC: C07C17/38
Filed: 1953-10-31
Abstract: A method of purifying benzene hexachloride contaminated with impurities incident to the production thereof by additive chlorination of benzene with chlorine, comprises heating benzene hexachloride to vaporize impurities therefrom in the presence of phosphoryl chloride, or phosphorus pentachloride, or phosphorus oxides or hydrates thereof.  Phosphorus oxides used are phosphorus trioxide, phosphorus tetraoxide and phosphorus pentoxide, and hydrates of these oxides such as phosphorous acid and ortho-, meta-, and pyrophosphoric acids, are used.  The phosphorus compound may be added after the benzene has been chlorinated but before the reaction mixture is heated to vaporize impurities, but is preferably present when the benzene is chlorinated.  The phosphorus compound may be dispersed in benzene, which is then chlorinated by bubbling chlorine gas through it, or by adding liquid chlorine.  The benzene may be chlorinated by adding it to a solution of chlorine in an inert solvent, such as carbon tetrachloride, in which case the phosphorus compound may be in the chlorine solution or in the benzene.  The chlorination may be activated by actinic light; or by a catalyst such as peroxydicarbonate esters of ethyl alcohol, isopropyl alcohol, n-propyl alcohol, cyclohexyl alcohol, ethylene glycol, allyl alcohol, 2-nitropropanol, phenol, ethyl lactate, benzyl alcohol, cresol, toluol, or ethyl salicylate (such esters may be made by reacting sodium peroxide with a chloroformate ester); or by a catalyst such as benzoyl peroxide, acetyl peroxide and tertiary butyl peroxide.  The benzene hexachloride is heated at a temperature between 100 DEG  C. and 200 DEG  C. to remove the impurities.

Filed: 1957-09-26
Abstract: 866,190. Step-by-step conveyers. LAMINOIRS A FROID DE THIONVILLE. Sept. 26, 1957 [Nov. 13, 1956], No. 30204/57. Class 78 (1). In an automatic installation for advancing a plurality of independently movable workpiece carriers through a series of stations at which mechanical, chemical, electrochemical or other operations are carried out, automatic transfer means for the carriers is provided between each adjacent pair of stations, such means being actuated when a carrier reaches the discharge end of a station. The installation described is one for chrome plating. The articles 5, Fig. 1, to be plated are attached to vertical members depending from a cross-bar 8 which is connected at its ends to longitudinal members 6, 7. These members are provided with runners 9 which slide on rails 3, 4 of V-section. At the discharge end of the station, the cross-bar 8 is engaged by forks 55 at the ends of arms 54 connected by a cross-member 56. These arms when rotated by a motor transfer the cross-bar to the tank 12 and into the first notches of racks 36 and then return to their initial position. The racks rest freely on rollers 42, Fig. 6, carried by arms 40 which are pivoted at 41 in a box 37 and carry counterweights 43. Partial withdrawal of the racks into the box is thus permitted. Rails 23, 24 rest on rollers 22 mounted on the upper edges of the tank walls. Projections 25 on the rails are engaged by the forked ends 26 of arms 27 which are pivoted on the tank walls. The lower ends of the arms 27 are connected by a cross-member which is reciprocated by a connecting rod. As the rails reciprocate, each carrier 8 passes from notch to notch along the racks and during this movement depresses the racks into the box as shown in Fig. 7. At the end of the movement the racks return to the upper position and prevent the carriers from moving backwards with the rails. At the end each carrier enters notches in the bars 45 and is removed therefrom by the forks 55 of the adjacent transferring mechanism. When a carrier is removed from the last tank 35 of the series, its bar 8 is deposited on the rails 3, 4 of the first station where it is engaged by a pusher 60 attached to a nut 61 which is engaged by a screw housed in a tubular guide 63. A contactor 64 on the nut co-operates with a reversing switch 65.
