The present invention is related to a hydrocarbon oxidation process. The process comprises bringing one or more hydrocarbons into contact with a source of oxygen in the presence of a radical initiator and a catalyst. The catalyst comprises an organic metal complex located on a catalyst support, and is obtained by partial decomposition of the organic metal complex. For example, the process can be used to produce dimethyl carbonate from dimethoxy methane. The invention is also related to a partially decomposed catalyst that comprises a silica support and an organic metal complex, wherein at least 5% of the organic compound remains in the catalyst. The organic metal complex comprises an organic compound and a metal-based compound wherein the metal is selected from copper, nickel, and combinations thereof. The invention is also related to a process for manufacturing of a catalyst comprising mixing L-arginine, a Cu-based compound, water, and optionally another metal-based compound to form a solution; impregnating the solution onto a silica support to form a catalyst precursor; and partially decomposing the L-arginine to form the catalyst so that at least 5% of L-arginine remains in the catalyst.
本发明涉及一种烃氧化过程。该过程包括将一个或多个烃与氧源在自由基引发剂和催化剂存在下接触。催化剂包括位于催化剂支撑物上的有机金属配合物,通过部分分解有机金属配合物获得。例如,该过程可用于从二甲氧甲烷生产二甲基碳酸酯。该发明还涉及一种部分分解的催化剂,该催化剂包括硅支撑物和有机金属配合物,其中催化剂中至少有5%的有机化合物残留。有机金属配合物包括有机化合物和基于金属的化合物,其中金属选自铜、镍和它们的组合。该发明还涉及一种催化剂制造方法,包括混合L-精氨酸、一种基于铜的化合物、水,以及可选的另一种基于金属的化合物以形成溶液;将溶液浸渍到硅支撑物上以形成催化剂前驱体;并部分分解L-精氨酸以形成催化剂,使催化剂中至少有5%的L-精氨酸残留。
