The present invention relates to a process for the oxidation of hydrocarbons, in particular of branched or unbranched saturated aliphatic hydrocarbons or of cycloaliphatic or alkylaromatic hydrocarbons, to alcohol, ketone and/or acid or polyacid compounds.
It relates more particularly to the oxidation, by an oxidizing agent comprising molecular oxygen, of cyclohexane to cyclohexanonol, cyclohexanone and/or adipic acid. The oxidation is carried out in the presence of a catalytic system comprising a catalyst based on at least one metal compound and a cocatalyst comprising an imide functional group, such as N-bromosuccinimide, N-bromomaleimide, N-bromohexahydrophthalimide, N,N′-dibromocyclohexane-tetracarboximide, N-bromophthalimide, N-bromotrimellitimide or N,N′-dibromopyromellitimide.
本发明涉及一种氧化烃的过程,特别是支链或直链饱和脂肪烃或环脂肪烃或烷基芳烃氧化为醇、酮和/或酸或多酸化合物。它更具体地涉及使用含有分子氧的氧化剂对环己烷氧化为环己烷醇、环己酮和/或己二酸的氧化反应。氧化反应在存在基于至少一种金属化合物的催化剂和包含亚胺官能团的协同催化剂的催化系统下进行,例如N-溴代琥珀酰亚胺、N-溴代马来酰亚胺、N-溴代六氢邻苯二酰亚胺、N,N'-二溴环己烷四羧亚胺、N-溴邻苯二酰亚胺、N-溴三苯酰亚胺或N,N'-二溴吡罗酰亚胺。
