| Several detergent range alcohols were reacted with sulfur trioxide (SO3) within a novel bench-scale falling-film sulfation apparatus. Products were produced in 100 ml to 4 L quantities. The quality of the final product was determined by measuring conversion, color, and inorganic sulfate content. At this small scale, conversions still approached 98-99 % with low color and salt formation, but as the SO3-to-feed mole ratio increased above 1.06, yellowing of the anionic surfactants was evident. The investigated organic feeds were various commercial alcohols produced by OXO or modified-OXO reactions with alkenes. |
