    Abstract: Hexahydrophthalic acids are produced by a process of catalytic hydrogenation of the salts of the corresponding phthalic acids at a temperature between 120 DEG and 350 DEG C. wherein the hydrogenation of a salt of a phthalic acid or a partial hydrogenation product thereof is carried out in the presence of a salt of the isomer of hexahydrophthalic acid which is not desired. The mixture thus obtained can be separated into the isomers in the form of salts or of free acids after the addition of acid. The conditions for the hydrogenation are conventional. The addition of the undesired isomer is preferably made in an amount approximately corresponding to the calculated amount of the undesired isomer expected in a conventional hydrogenation.

    Abstract: Carbonyl sulphide contained in gas mixtures obtained, e.g. from oil gasification processes, is hydrolysed to hydrogen sulphide at a temperature in the range of 100-120 DEG C. in the presence of a catalyst comprising a basic magnesium carbonate in which the molar ratio MgO : CO2 is from 1 :0.65 to 1 :0.80. The catalyst may be supported on a carrier.ALSO:Carbonyl sulphide contained in gas mixtures is hydrolysed to hydrogen sulphide at a temperature in the range 100-120 DEG C. in the presence of a catalyst comprising a basic magnesium carbonate in which the molar ratio MgO : CO2 is from 1 : 0.65 to 1 : 0.80. The catalyst may be supported on a carrier and may contain 10-20% wt. of the basic carbonate. The basic carbonate may be prepared by reacting an aqueous solution of a magnesium salt with a carbonate at 20-90 DEG C., drying at 100-120 DEG C., and then if desired heating for 5-15 hours at 130-160 DEG C.
