    摘要: Disclosed are compositions and methods for preventing or reducing polymer formation and polymer deposition in equipment used in petrochemical processes. An antifoulant composition includes a combination of one or more antioxidants; one or more antipolymerants; one or more dispersants; and one or more solvents. A method of preventing or reducing fouling of process equipment used in an industrial process is also described. The method includes introducing into the process equipment an antifoulant composition, the antifoulant composition comprising a combination of one or more antioxidants; one or more antipolymerants; one or more dispersants; and one or more solvents.

    摘要: A polymerization inhibitor for a silane enables purification of the silane to a high degree because a polymer is not formed even when heating to distill the silane, even when a cyclic silane monomer is present. A high-purity cyclic silane composition is obtained, in particular high-purity cyclopentasilane, that can be polymerized and applied onto a substrate as a coating-type polysilane composition and fired to produce a good silicon thin film with high conductivity. The polymerization inhibitor includes a secondary or tertiary aromatic amine. The aromatic group is a phenyl group or a naphthyl group. The polymerization inhibitor is present in a proportion of 0.01 to 10 mol % per mole of the silane. In the polymerization inhibitor, a boiling point of the aromatic amine is 196° C. or higher.
