| titleOfInvention | Process for sulphonating organic compounds |
| abstract | 1,146,127. Sulphonating organic compounds. ALLIED CHEMICAL CORP. 5 Oct., 1967 [11 Oct., 1966], No. 45564/67. Heading C2C. Process for the sulphonation (sulphation) of a sulphonatable organic liquid which comprises contacting the organic compound with a mixture of SO 3 and an inert diluent gas, separating contaminated inert diluent gas from the liquid sulphonated product, scrubbing the contaminated gas with more of the said organic compounds in an amount which in batch operation is at least 15À2 g/m.<SP>3</SP> of said contaminated gas and in continuous operation is at least 760 g/m.<SP>3</SP> per hour of said contaminated gas, and reusing the scrubbed gas in the first step adding fresh SO 3 thereto at or near the beginning of the reaction zone. The scrubbing liquid may be utilized as part or all of the compound to be sulphonated provided that said scrubbing liquid and any fresh sulphonated compound added together contain not more than 95% by weight of the sulphonated product. The feed pipe to the scrubber may be flushed with a small amount of scrubbing liquid to prevent deposition of residue. Examples use a branched chain dodecylbenzene, a linear dodecylbenzene, a linear alkyl benzene of mol. wt. 238, and ethoxylated lauryl alcohol. In batch examples the SO 3 feed and the recycled gas are fed through concentric pipes dipping below the surface of the liquid reactant, the outer pipe carrying the recycled gas extending slightly beyond the inner pipe. Continuous operation is also described. |
