    Abstract: 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.

    Abstract: The present invention relates to a process for preparing amines by reacting sugar alcohols with hydrogen and an aminating agent selected 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 1 to 40 MPa (from 10 to 400 bar). 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 sugar alcohol is preferably obtained by hydrogenating the corresponding sugars. 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.
