Abstract
A dispersant for vinyl acetate process streams has been found, which dispersant acts as an antifoulant, preventing formation of fouling tars, polymers, debris, and the like, in the process streams involved in the manufacture of vinyl acetate monomer. The antifoulant/dispersant is primarily composed of hydrocarbonaceous sulfonic acids which may optionally be admixed organic polar solvents and tall oil fatty acids.
