| 摘 要： | 直链烷基苯是生产阴离子表面活性剂直链烷基苯磺酸盐的重要原料。2000年以美国环球油品公司(UOP)的脱氢法工艺生产的直链烷基苯占世界直链烷基苯产量的88％。脱氢法以液体氢氟酸为催化剂由正构烯烃与苯进行烷基化反应生产直链烷基苯。由于液体氢氟酸催化剂具有较强的腐蚀

| Abstract: | A continuous mixed flow reactor, in which the supported heteropolyacid catalyst HRP-12 was suspended, was adopted in the experiment. Experimental data were used in parameters estimation for kinetics equation of benzene alkylation with linear olefin. Parameters, including reaction rate constant, activation energy and reaction order in olefin molar concentration, were determined as 13 530 s－1, 48743Jmol－1 and 1 respectively. The kinetic equation for benzene alkylation with linear olefin was thus established. Statistics test and model prediction have shown that the kinetics equation is highly credible under the condition α=0.05 and well corresponds with reaction principle. |
