Abstract:
Sulphonation and sulphated products, i n the form of solutions of their
sodium salts, are main components in the world-wide manufacture of detergents.
These products have found application also in many of the processes
of the textile and leather industries. But the use of detergents, in solid
and liquid form, has been the main reason for production capacity growth in
sulphonation alkylbenzenes. Sulphonation of linear or branched alkylbenzenes
may be achieved through application of sulphuric acid, chlorosulphonic acid or
sulphur trioxide. The last-mentioned process is widely used because there are
no problems in disposing of residual acids; moreover, the product I s sodium
sulphate content is low.
