ABSTRACT:
A process for manufacturing a highly concentrated sulfate solution or slurry which comprises neutralizing a sulfuric ester of higher alcohol or its ethoxylate with an aqueous caustic alkali solution, thereby preparing a crude neutralization product containing the sulfate in the range of from 45 wt. % to 55 wt. % and the caustic alkali in the range of from 1.5 wt. % to 3.5 wt. % and having a viscosity less than 50 poise; and commingling the resulting crude neutralization product with the sulfuric ester in the range of from 30 parts by weight to 100 parts by weight per 100 parts by weight of the crude neutralization product and a highly concentrated caustic alkali solution capable of sufficiently neutralizing the sulfuric ester, thereby reducing the quantity of sulfate contained in the resulting mixture in the range of from 60 wt. % to 75 wt. % and the quantity of caustic alkali contained therein less than 0.5 wt. % of the quantity of sulfate.
