    • 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.
    • 本发明涉及烃氧化方法。 该方法包括在自由基引发剂和催化剂的存在下使一种或多种烃与氧源接触。 催化剂包含位于催化剂载体上的有机金属络合物,并通过有机金属络合物的部分分解获得。 例如,该方法可用于从二甲氧基甲烷生产碳酸二甲酯。 本发明还涉及包含二氧化硅载体和有机金属络合物的部分分解的催化剂,其中至少5%的有机化合物保留在催化剂中。 有机金属络合物包括有机化合物和金属基化合物,其中金属选自铜,镍及其组合。 本发明还涉及制造催化剂的方法,其包括将L-精氨酸,Cu基化合物,水和任选的其它金属类化合物混合以形成溶液; 将溶液浸渍到二氧化硅载体上以形成催化剂前体; 并部分分解L-精氨酸以形成催化剂,使得至少5%的L-精氨酸保留在催化剂中。
