The reaction of intromolecular dehydration of crudehydroxyethyl-piperzine to synthesis triethylenediamine was studied in this paper. A series of catalysts were chosen,prepared and examined. Reaction parameters including influencing temperature,space velocity,and concentration were optimize. Thus,when SrHOP4 containing Ba2+ was empolyed as catalyst,the concentration of crude hydroxyethyl-piperazine was 60%,the space velocity of raw material gas was 2 000 h-1 and under 360℃,the conversation of the material reached up to 100% and the selectivity of triethylenediamine is above 90%. After distillation and recrystallization of the obtained reaction mixture the purity was over 99%.
