    Abstract: 1,153,584. Sulphonic acids. FARBWERKE HOECHST A.G. 13 June, 1966 [11 June, 1965], No. 26185/66. Heading C2C. In the sulphonation of straight-chain paraffin containing 10-30 carbon atoms by SO 2 and oxygen, the hydrocarbon is first purified by a molecular sieve process or the urea process and further purified by intimately mixing the hydrocarbon with a solution of sulphur trioxide in H 2 SO 4 and by subsequently separating the hydrocarbon layer from the H 2 SO 4 layer and the sulphonation is initiated by high-energy ionizing radiation, UV radiation, ozone or a peroxy compound and is continued without further irradiation and without the introduction of any further substance suitable for initiating a free-radical chain reaction. The initiation of the reaction may be by γ, # or W radiation, X- rays, electrons rich in energy from accelerators, ozone, ozone containing oxygen or peroxy compounds for example peracetic acid, cyclohexyl persulphonic acid or acetyl cyclohexansulphonyl peroxide. The sulphonation may be carried out using a mixture of SO 2 and air. The acids formed may be converted into salts.
