Abstract: 1357071 Modified phyllosilicates GERDEC GROUPEMENT & D'ETUDES DE RECHERCHES ET DE DEVELOPPEMENT EMCCFE 11 July 1972 [13 July 1971] 32389/72 Heading C1A [Also in Division C3] A phyllosilicate mineral is treated in a process comprising, as a first step, acid hydrolysis of the mineral, and as a second step, chlorination of the hydrolysed mineral whereby chlorine atoms are fixed on the mineral. The hydrolysis may be achieved by reacting the mineral with HCl, H 2 SO 4 , HNO 3  or CH 3 .COOH, preferably dissolved in a mixture of water with methanol, ethanol, isopropanol, acetone or MEK. The chlorination may be achieved using thionyl chloride or phosgene; the thionyl chloride may be dissolved in benzene, toluene, xylene, heptane or octane. As a third step the mineral may be grafted with organic radicals to form precursors for polymerization, e.g. by treatment with organo-metallic compounds or alcohols. Minerals specified are chrysotile, sepiolite, mica and vermiculite.

Title: Production of halogens
Inventor: DIJK CHRISTIAAN PIETER VAN
IPC: C01B7/04
Filed: 1964-08-12
Abstract: In an oxidation reaction of hydrogen halide, the effluent gases containing water, halogen and hydrogen halide are dried under adiabatic conditions with hygroscopic solution of a metal halide (e.g. CaCl2) or H2SO4.  The hygroscopic solution increases in temperature and is subsequently dehydrated by flashing under reduced pressure and adiabatic conditions; it is recycled to the drying zone. The dried effluent gas is condensed to obtain substantially pure halogen; if this is chlorine the effluent gases should be dried to a water dew point of less than - 30 DEG  F. in the drying zone.  A portion of the flashed hygroscopic solution (e.g. 20%) may be recycled to the drying zone at a temperature below that at which the dried effluent is removed. A two-stage drying zone may be employed, the hygroscopic solution is supplied to the first stage at the temperature at which it leaves the flashing zone and at least 85% of the moisture may be removed in this zone, the remainder being removed by the cooled hygroscopic solution which is supplied to the second portion of the zone.  The drying zone is constructed of acid resistant material and the H2SO4 supplied countercurrent to the effluent gas flow in a zone packed, e.g., with raschig rings.
