DEVELOPMENT OF THE CATALYSTS FOR INDUSTRIAL PRODUCTION OF N,N-DIMETYLI ALKYL(DODECYL)AMINE

Dong Guoxing;Yan Tingfang;Wang Yan  
bstractAbstract:The catalysts for the indnstrial production of N-dimethyl alkyl(dodecyl)amine,which are of high conversion activity of dodeecyl alcohol(99%)andhigh triamine yield(94-95%),have been developed by us.It is discovered that theSio_2/Al_2O_3 of the supports has obvious influence on the activity and selectivity ofthe catalysts,and the amount of metals supported.The most appropriate percentageis 25-30%.It is proposed that the particles of Cu-Ni with certain Cu/Ni on thesurface of the catalysts may be the catalytic reaction centers.
