METHOD FOR PRODUCING ETHYLENEDIAMINE |
摘要 |
<p>The invention relates to a process for preparing ethylenediamine by hydrogenation of aminoacetonitrile over a catalyst, wherein the hydrogenation is carried out in a solution comprising aminoacetonitrile, water in a proportion of from 0 to 60% by weight and a solvent and the aminoacetonitrile comprised in the solution is fed into the reaction vessel at a rate which is not greater than the rate at which the aminoacetonitrile reacts with hydrogen in the hydrogenation.</p> |
