研究了磷钨酸 (H3PW12 O4 0 ,简记为PW12 )及其钠盐 (NaxH3-xPW12 O4 0 ,简记为NaxH3-x,x =1～ 3)催化苯酚与苯乙烯的烷基化反应 .NH3 TPD及吡啶热脱附结果表明 :随着钠含量的增加 ,催化剂的酸性及催化活性皆依次降低 :PW12 >Na1H2 >Na1.5H1.5>Na2 H1>Na2 .5H0 .5>Na3.
The alkylation of phenol with styrene catalyzed by H3PW12 O4 0 (abbreviated as PW12) and its sodium salt (NaxH3-xPW12 O4 0, abbreviated as NaxH3-x, x = 1 ~ 3) The results of thermal desorption of NH3TPD and pyridine show that the acidity and catalytic activity of the catalyst decrease with the increase of sodium content: PW12> Na1H2> Na1.5H1.5> Na2 H1> Na2 .5H0.5> Na3.
