Catalytic dehydration of 1-octanol over H₃PO₄/ZrO₂–TiO₂–surfactant (H₃PO₄/ZTS) mixed oxides at 350 °C for production of 1-octene was investigated. ZrO₂–TiO₂ (ZT) with Zr:Ti molar ratio = 1:1 was prepared with and without cetylpyridinium bromide surfactant and modified by different concentration of H₃PO₄. These catalysts were characterized by several methods such as XRD, BET, pyridine adsorption, and NH₃-TPD. The prepared catalysts with surfactant showed better selectivity and activity than the prepared catalysts without surfactant for 1-octene synthesis. Maximum selectivity to 1-octene in 1-octanol dehydration was attained over 15 wt% H₃PO₄/ZTS, while maximum conversion of 1-octanol with lower selectivity to 1-octene was achieved over 35 wt% H₃PO₄/ZTS. At 350 °C and with WHSV 1.978 h⁻¹, the maximum conversion of 1-octanol over 15 wt% H₃PO₄/ZTS was 68.8%, with 48.3% selectivity to 1-octene.

研究了H ₃ PO ₄ / ZrO ₂ -TiO _2-表面活性剂（H ₃ PO ₄ / ZTS）混合氧化物在350°C下催化1-辛醇脱水制备1-辛烯的过程。在有和没有十六烷基溴化吡啶表面活性剂的情况下，制备Zr：Ti摩尔比= 1：1的ZrO ₂ -TiO ₂（ZT），并通过不同浓度的H ₃ PO _4进行改性。这些催化剂通过XRD，BET，吡啶吸附和NH ₃等几种方法进行了表征。-TPD。所制备的具有表面活性剂的催化剂显示出比未制备用于1-辛烯合成的表面活性剂的催化剂更好的选择性和活性。在15 wt％H ₃ PO ₄ / ZTS中达到了对1-辛醇脱水的1-辛烯的最大选择性，而在35 wt％H ₃ PO ₄ / ZTS中实现了具有较低选择性的1-辛醇向1-辛烯的最大转化率。。在350°C且WHSV为1.978 h ^-1时，相对于15 wt％H ₃ PO ₄ / ZTS的1-辛醇最大转化率为68.8％，对1-辛烯的选择性为48.3％。
