There is provided a process for preparing a carbamate compound, which is easy and commercially advantageous in that a carbamate compound can be produced with high yield from an amine compound and a carbonate compound. A process for preparing a carbamate compound which comprises the step of reacting an amine compound which has at least one amino group per molecule wherein the amine compound is selected from the group consisting of an aliphatic amine which may be substituted by an alicyclic group or an aromatic group or which may be interrupted by an alicyclic group or an aromatic group, and an alicyclic amine which may be substituted by an aliphatic group, with a carbonate compound in the presence of at least one organic solvent selected from the group consisting of a saturated cyclic hydrocarbon, an unsaturated cyclic hydrocarbon, and a non-cyclic ether by using a hydrolase.
提供了一种制备碳酸酯化合物的过程,该过程简单且具有商业优势,因为碳酸酯化合物可以从胺化合物和碳酸酯化合物高产率地生产出来。制备碳酸酯化合物的过程包括以下步骤:在至少每分子含有一个氨基团的胺化合物中选择一种胺化合物,所述胺化合物选自以下组合:可能被脂环族或芳香族取代的脂肪族胺或可能被脂环族或芳香族中断的脂肪族胺,以及可能被脂肪族取代的脂环族胺;将所述胺化合物与碳酸酯化合物在至少选择自饱和环烃、不饱和环烃和非环氧化物的有机溶剂中,在水解酶的作用下反应。
