“…The C-12 alkylated benzene fraction ("dodecylbenzene detergent alkylate") is of major commercial interest for making sulfonates widely used as surface-active agents. Sulfur trioxide vapor has been employed in the laboratory (207, 280), in the pilot plant (1,114,187), and on a commercial scale. The same procedure has been employed to sulfonate the high-boiling alkylate benzene fraction ("polydodecylbenzene") (203), and dodecyltoluene (182).…”

“…It is therefore somewhat surprising that a strong reagent like S03, which favors sulfone formation, can be used at all. Observance of the following conditions (394) makes this possible, using S03 either as vapor or liquid: (1) use of solvents (liquid SOs for the S03; carbon tetrachloride for the polymer, which is poorly soluble in S02) (393); (2) low dilutions (1 to 10%);…”

A primary limitation to alkylbenzene sulfonation processes has been the lack of a rapid method to sense the quality of sulfonation. This is especially true for a process using sulfur trioxide where both the level of sulfonating agent and time are critical: too little reagent results in high oils; too much reagent degrades product color; and a delay in the process also degrades color. Although steam distillation of oils from the neutralized sulfonate can be conducted in about one and one-half hours for commercial dodecylbenzene derivatives, far greater time is required for higher molecular weight homologs. Extraction of oils requires about one hour and more operator time than distillation.
