Method and application for synthesis of methanol by hydrogenation of unsubstituted carbamate

The invention discloses a method and application for the synthesis of methanol by hydrogenation of unsubstituted carbamate. The method uses the unsubstituted carbamate as a substrate, a solvent is added, and the methanol is synthesized by hydrogenation under the action of a catalyst and an alkaline auxiliary agent. The method provided by the invention has the advantages that the raw materials areeasy to obtain, the costs are low, the reaction conditions are mild, negative factors of low selectivity, harsh conditions and the like of methanol preparation by direct hydrogenation of CO2 can be overcome, CO2 can be indirectly utilized, and the method can directly link with the ammonia synthesis industry, and is friendly to the environment. At the same time, raw materials for a source reactiononly involve NH3, CO2 and an alcohol, and the method can directly link with the ammonia synthesis industry and has good practical application prospects. 种非取代氨基甲酸酯加氢合成甲醇的方法及应用，该方法以非取代氨基甲酸酯为底物，加入溶剂，在催化剂和碱性助剂作用下加氢合成甲醇。该方法原料易得，成本低
