| titleOfInvention | Method of sulfonating mixtures of olefin and aromatic hydrocarbons |
| abstract | Improved processes for obtaining biodegradable detergents of good color using less sulfonating agents and minimizing or abolishing the requirement for decoloring; in which a mixture including ortho-dialkyl benzenes having linear alkyl radicals and linear olefin hydrocarbons (prepared by cyclization dehydration of normal paraffin stock having 14 to 24 carbon atoms) is sulfonated and neutralized twice with the organic phase from the first sulfonation forming the charge for the second. The efflux from at least the second neutralization is saponified and the aqueous phase of such saponification efflux yields the desired detergent. The first sulfonation is effected in the presence of a deficit of the sulfonating agent with respect to the sulfonatable hydrocarbons and the second with an excess. |
