| titleOfInvention | Process for the continuous reaction of organic compounds with sulfur trioxide |
| abstract | Diluted gaseous sulfur trioxide is reacted with a liquid sulfonatable or sulfatable compound or mixtures thereof, e.g. an alkyl benzene or fatty alcohol, by: (a) diluting said SO3 with a gas relatively inert with respect to the sulfonation reaction within a volume ratio of SO3:inert gas of from 1:5 to 1:50, (b) forming a reactant liquid comprising said sulfonatable organic compound or mixtures thereof and its sulfonation derivative which has been recycled, (c) passing said reactant liquid through a shear-producing means to establish a zone of turbulent flow, the temperature of said reactant liquid in said zone of turbulent flow being from 90 DEG F (32.2 DEG C) to 130 DEG F (54.4 DEG C). (d) introducing said diluted SO3 gas into said zone of turbulent flow at a temperature of from 80 DEG F (26.7 DEG C) to 130 DEG F (54.4 DEG C) to form a dispersion of said diluted SO3 gas in said reactant liquid at a gas to liquid volume ratio of from 5:1 to 30:1, (e) maintaining contact of said reactant liquid and said diluted SO3 gas for a period of at least 1.5x10<-3> seconds to form a reaction liquid and a gas phase containing essentially no SO3, (f) separating a major portion of said gas phase from the reaction liquid, (g) removing a portion of the reaction liquid as sulfonated product, the weight ratio of sulfonated product removed to the remainder of the reaction liquid being in the range of from 1:25 to 1:500, (h) recycling said remainder of said reaction liquid and adding said sulfonatable organic compounds or mixtures thereof at a rate of from 100% to 105% of the stoichiometric equivalent of the rate of SO3 addition in step (d) to form monosulfonates of the sulfonatable organic compound or mixtures thereof. f |
