[DE] KATALYTISCHES VERFAHREN ZUR HERSTELLUNG VON CARBONYL-VERBINDUNGEN [EN] CATALYTIC METHOD FOR THE PRODUCTION OF CARBONYL COMPOUNDS [FR] PROCÉDÉ CATALYTIQUE POUR LA PRODUCTION DE COMPOSÉS CARBONYLE
摘要:
该发明涉及一种催化方法,用于制备至少具有一个醛基或酮基的脂肪族和芳香族羰基化合物,这些化合物也可以同时具有醛基和酮基。一种具有至少一个脂肪族和/或芳香族功能基团的起始物质,其具有以下式(I)中的R1为氢、烷基或芳基,X为氢或在催化反应期间可被亚砜基取代的基团,n为1至8之间的整数值,与亚砜和/或硫化物在铁盐或铁/铜或银/铜盐的氧化还原对的存在下,在氧化剂的作用下被氧化,其中氧化剂的氧化还原电位为Eo > +2 V vs. NHE,亚砜和/或硫化物被用作催化剂。该方法允许高选择性地制备羰基化合物,特别是(多)醛和(多)酮,减少或基本上阻止了醇和羧酸、二甲基化产物和其他副产物的生成。所得到的终产物在化工行业中被广泛用作重要的中间体和终端产品。
