US08835691B2 Process for homogeneously catalyzed, highly selective direct amination of primary alcohols with ammonia to primary amines with a high volume ratio of liquid phase to gas phase and/or high pressures 有权
将具有氨的伯醇与氨的均相催化，高选择性直接胺化的方法具有液体相与气相和/或高压的高体积比

Process for homogeneously catalyzed, highly selective direct amination of primary alcohols with ammonia to primary amines with a high volume ratio of liquid phase to gas phase and/or high pressures
摘要：
The present invention relates to a process for preparing primary amines comprising the process steps A) provision of a solution of a primary alcohol in a fluid, nongaseous phase, B) contacting of the phase with free ammonia and/or at least one ammonia-releasing compound and a homogeneous catalyst and optionally C) isolation of the primary amine formed in process step B), characterized in that the volume ratio of the volume of the liquid phase to the volume of the gas phase in process step B is greater than 0.05 and/or in that process step B is carried out at pressures greater than 10 bar.
摘要（中）：

本发明涉及一种制备伯胺的方法，包括以下工艺步骤：A）将伯醇在流体，非气相中提供，B）使相与游离氨和/或至少一种氨释放的相接触 化合物和均相催化剂，并任选地C）分离方法步骤B）中形成的伯胺，其特征在于在方法步骤B中液相体积与气相体积的体积比大于0.05， /或在该方法中，步骤B在大于10巴的压力下进行。
