Antifoulant for acrylic acid purification

摘要: The invention comprises a method of dispersing foulants, residues, gums, precipitates, polymeric tars and other highly oxidized carbonaceous which can be formed in the process manufacture recovery acrylic acid. comprises adding to liquid or gaseous phases passing through, stored acid process equipment, an effective antifouling amount dispersant is stable the environment within compatible with equipment used for the acid, said antifoulant having structure: R(SO 3 ) n M wherein R hydrocarbonaceous group from 1-34 carbon atoms chosen linear branched alkyl groups, aromatic, cyclic, alkaryl, aralkyl, or alkenyl diphenyl ether dialkyl naphthalene groups, mixtures thereof; M chosen consisting of hydrogen, alkali metal, alkatine earth ammonium cation, alkyl ammonium ranges 1 about 6.
