Taking hydrothermal crystallization as its method ,trithylene tetramine ( TETA) as the template agent ,and cupric sulphate as copper source ,this study synthesizes a new kind of molecular sieve — Cu-SAPO-102 .It observes the effects of all elements on the synthesis and puts forwards the optimized crystal-lization conditions for CuSAPO-102 with high crystallinity and good yield .Then it probes into the physi-cochemical properties of products by means of XRD ,SEM,DTA-TG and physical adsorption .The results show that the synthetic products belong to a new molecular sieve with good purity and favorable crystal -lized state;the mean grain size is about 50 .0μm;the framework collapses at about 700℃;it is a micro-porous molecular sieve with median pore width of 4 .721 ?.
