标题:芳烃的选择性电化学氧化及单/多羰基化合物的制备
摘要:在温和条件下开发了选择性电化学氧化.凭借这种电化学氧化,可以从不同的芳烃以中等至优异的收率和选择性制备各种单羰基和多羰基化合物.生成的羰基化合物可以在一锅反应中进一步转化为α-酮酰胺,高烯丙醇和肟.特别是,在单锅连续电解中制备了一系列 α-酮酰胺.机理研究表明,2,2,2-Trifluoroethan-1-Ol (Tfe) 可以与催化剂物种相互作用并生成相应的氢键配合物,以提高电化学氧化性能.

摘要:Methods for preparing alkenylphenone corrosion inhibiting compositions may include providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Corrosion inhibiting compositions may include an alkenylphenone, which may be prepared by a method including providing an arylacetone and reacting the arylacetone with formaldehyde in the presence of a strong base catalyst. Methods of inhibiting corrosion of a steel surface of an oilfield equipment component may include contacting the steel surface with an aqueous solution comprising a corrosion inhibitor. The corrosion inhibitor may include a composition containing an alkenylphenone prepared by reacting an arylacetone with formaldehyde in the presence of a strong base catalyst.

摘要:The present disclosure provides for the synthesis of branched polyamines. In embodiments, branched polyamines may be formed by reacting a branched polyol with a nitroaryl carboxylic acid to form a nitrobenzoyl ester which, in turn, may then be subjected to a hydrogenating step to form the branched polyamine. The resulting branched polyamine may then be reacted with another hydrogel precursor to form a hydrogel.
