ABSTRACT:
A process of manufacturing C.sub.10 -C.sub.20 .alpha.-olefin sulfonate solution of high concentration, which comprises subjecting .alpha.-olefin sulfonates having 10-20 carbon atoms to neutralization and hydrolysis in the presence of (a) an alkaline material equivalent to the sum (A+B) of an amount of alkali (A) necessary for performing neutralization and hydrolysis of said sulfonates stoichiometrically and an amount of alkali (B) equivalent to 0.2-1.5 times as much as said amount of alkali (A) by weight, (b) an alkylene oxide derivative and/or a polyvinyl alcohol equivalent to 0.2-2 times as much as said amount of alkali (B) by weight, and (c) water necessary for making the water content of the neutralization-hydrolysis product less than 50%.
