| titleOfInvention | Method for producing surfactant composition |
| abstract | An object of the present invention is to provide a method for producing a surfactant composition containing a sulfonated product and having a low odor. A method for producing a surfactant composition comprising a polyhydric alcohol (A), water (B) and a sulfonated product (E), comprising 4 carbon atoms in the presence of (A) and (B). Step of converting esterified product (C) of ˜22 unsaturated dicarboxylic acid (c1) and C 1-22 aliphatic monoalcohol (c2) to sulfonated product (E) with sulfonating agent (D) (1) And the sulfonating agent (D) is at least one selected from the group consisting of sulfurous acid, hydrogensulfite, disulfurous acid and salts thereof, and the step (1) is a conversion from (C) to (E) Sulfonating at 90-115 ° C. until the rate reaches 75-95%, and further sulfonation at 116-135 ° C. until the conversion rate from (C) to (E) reaches 96% or more. The manufacturing method of surfactant composition which has a process (1-2) to do. [Selection figure] None |
