Aldol polymer fouling in petrochemical plant is an undesirable, which need to remove for increases the efficiency of downstream process. In this paper, investigated inhibition and dissolution efficiency of the aminopropyl trimethoxy silane (APTMS), aminopropyl triethoxy silane (APTES), sodium salt of aminopropyl trimethoxy silane (SS-APTMS), sodium salt aminopropyl triethoxy silane (SS-APTES) were studied at different molar ratio of Vinyl acetate (VA): amino alkoxy silane (antipolymerant). The sodium salt of 6-Aminohexanoic acid (SS-AHA) and ethanolamine (EA) was used as reference for comparison. The efficiency of antipolymerant for inhibition and dissolution was measured as % T by UV spectrophotometry. Solium salt of amino alkoxy silane showed good efficiency for inhibition and dissolution process. Furthermore, the presence of alkoxy group with amino group facilitates inhibition as well as dissolution of aldol polymer in alkaline media, while compounds with amino group acts as inhibitor for aldol condensation only.

Keywords: Aldol condensation, fouling, inhibition, dissolution, amino alkoxy silane, % transmission
