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.

标 题:Process for producing diphenylethers and esters
发明人：LOURENS GERHARDUS JOHANNES
权利人:DOW CHEMICAL CO
摘要:An improved synthesis of diphenylethers, and in particular, the bacteriostat 2,4,4'-trichloro-2'-hydroxydiphenylether, is described wherein 2'-acetyl-2,4,4'-trichlorodiphenylether is oxidised under Baeyer-Villiger conditions to produce 2'-acetoxy-2,4,4'-trichlorodiphenylether in near quantitative yield. Best oxidative conditions include the use of anhydrous permaleic acid produced in situ. The ester is purified readily by simple recrystallization, as no dibenzofurans and only minor amounts of byproducts are formed in the process. The ester is converted into the desired halogenated phenolic diphenylether, 2,4,4'-trichloro-2'-hydroxydiphenylether, by hydrolysis or transesterification. The final product is purified to a high degree by vacuum distillation and crystallization to meet current purity standards for approved applications.
