Abstract:
The invention relates to an extractive distillation composition for at least partially separating a mixture of hydrocarbon compounds comprising: a. at least on one organic sulfoxide of the formula R1nullSOnullR2, and b. at least on one organic sulfone of the formula R3nullSO2nullR4 nullwherein R1, R2, R3, and R4 have at least one carbon atom and can be the same or different, and to processes for extractive distillation employing the extractive distillation composition.
