The present invention relates to a process for preparing amines by reacting glycerol with hydrogen and an aminating agent from the group of ammonia and primary and secondary amines in the presence of a catalyst at a temperature of from 100° C. to 400° C. and a pressure of from 0.01 to 40 MPa (from 0.1 to 400 bar). Preference is given to using glycerol based on renewable raw materials. The catalyst preferably comprises one metal or a plurality of metals or one or more oxygen compounds of the metals of groups 8 and/or 9 and/or 10 and/or 11 of the Periodic Table of the Elements. The invention further relates to the use of the reaction products as an additive in cement or concrete production and in other fields of use. This invention further provides the compounds 1,2,3-triaminopropane, 2-aminomethyl-6-methylpiperazine, 2,5-bis(aminomethyl)piperazine and 2,6-bis(aminomethyl)piperazine.
本发明涉及一种通过在催化剂存在下,将甘油与氢气和来自氨和一次和二次胺组的氨化剂反应,在温度从100°C至400°C和压力从0.01至40兆帕(从0.1至400巴)条件下制备胺的方法。优选使用基于可再生原料的甘油。催化剂优选包括元素周期表第8和/或9和/或10和/或11族金属或多种金属或这些金属的一个或多个氧化物。该发明还涉及将反应产物用作水泥或混凝土生产中的添加剂以及其他用途领域。该发明还提供了化合物1,2,3-三胺丙烷,2-氨基甲基-6-甲基哌嗪,2,5-双(氨基甲基)哌嗪和2,6-双(氨基甲基)哌嗪。
