    Abstract: 1. A PROCESS FOR THE PRODUCTION OF A CHLOROSTANNANE HAVING THE GENERAL FORMULA:

    Z-SN(-Y)(-CL)2

    WHEREIN Y IS A CHLORINE ATOM OR A SATURATED OR UNSATURATED ALIPHATIC, CYCLOALIPHATIC OR AROMATIC HYDROCARBON RADICAL, AND Z IS EITHER A GROUP Z1 HAVING THE GENERAL FORMULA:

    (R)N-PHENYLENE-

    IN WHICH R REPRESENTS A CHLORINE ATOM OR AN ALKYL RADICAL WITH 1 TO 4 CARBON ATOMS AND WHEREIN N IS 0, 1. OR 2, OR A GROUP Z2 HAVING THE GENERAL FORMULA:

    R1-C(-R2)=C(-R3)-

    IN WHICH R1, R2, AND R3 WHICH MAY BE IDENTICAL OR DIFFERENT, EACH REPRESENTS A HYDROGEN ATOM OR A SATURATED OR UNSATURATED ALIPHATIC, CYCLOALIPHATIC OR AROMATIC HYDROCARBON RADICAL, OR TWO RADICAL R1 AND R3 TOGETHER WITH THE TWO ETHYLENTIC CARBONS TO WHICH THEY AR BONDED, FORM AN UNSATURATED RING HAVING 5 OR 6 CARBON ATOMS IN THE RING, IN WHICH A TIN HALIDE OF THE GENERAL FORMULA:

    Y-SN-CL3 II

    IS REACTED IN THE PRESENCE OF ALUMINUM CHLORIDE, WITH AN ORGANOSILICON COMPOUND OF THE FORMULA:

    (Z)A-SI(-CL)B(-CH3)(4-(A+B))

    WHEREIN Y AND Z ARE AS DEFINED ABOVE, A IS 1, 2, 3 OR 5, B IS 0, 1, 2 2 OR 3, THE SUM (A+B) IS NOT GREATER THAN 4, B BEING 0 WHEN Z IS Z2.

    Abstract: 1,181,187. Acetic acid. RHONE-POULENC S.A. 25 Sept., 1968 [26 Sept., 1967], No. 45588/68. Heading C2C. Acetic acid is prepared by contacting but-2- ene with nitric acid in the presence of a vanadium compound as a catalyst. The nitric acid may be in aqueous solution (40-90% nitric acid) at a temperature of 20 to 100‹ C. Vanadium compounds mentioned are vanadium pentoxide, vanadium halide, VF 5 , vanadium oxyhalides, VOF 3 , VOBr 3 and VOCl 3 , vanadic sulphate, nitrate or phosphate, alkali metal or ammonium orthovanadates, metavanadates, hypovanadates and hexavanadates, vanadyl sulphate, nitrate and phosphate and vanadium sulphates. The nitrous vapours may be reoxidized to nitric acid either in the oxidation medium or in an external zone by oxygen or air.
