    摘要: As antifoulants in the processing of crude oil to minimize deposition of condensates and polymeric deposits on heat exchangers, compounds of the following structure have been utilized: ##STR1## X = OH, NH.sub.2, NHR, NHCH.sub.2 CHOHR (R = straight or branched chain alkyl containing 2 to 20, preferably 6 to 16, carbon atoms.)Y = h, ch.sub.2M = ammonia, amine containing 1-54 carbons where the total number of carbon atoms in X and M is .gtoreq. 8 but .ltoreq. 54.n .gtoreq. 1As preferred compounds, sulfanilic acid amine salts are preferred in the above formula where X = NH.sub.2, NHR, NHCH.sub.2 CHOHR.Also preferred are phenolic compounds which are sulfonated and subsequently partially or completely neutralized with amines as in the above formula where X = OH.The compounds show an effective dosage range from about 40 ppm to 300 ppm and the effective percent reduction in fouling in crude oils ranging from 42-94%.
