NICKEL/TITANIUM OXIDE-SILICON OXIDE CATALYST FOR SYNTHESIZING TERPINENE-4-OL, PREPARATION METHOD THEREOF, AND METHOD OF SYNTHESIZING TERPINENE-4-OL USING THE SAME
NICKEL/TITANIUM OXIDE-SILICON OXIDE CATALYST FOR SYNTHESIZING TERPINENE-4-OL, PREPARATION METHOD THEREOF, AND METHOD OF SYNTHESIZING TERPINENE-4-OL USING THE SAME
The present invention discloses a nickel/titanium oxide-silicon oxide catalyst for synthesizing terpinene-4-ol as well as a preparation method and method of synthesizing terpinene-4-ol using the same. The preparation method includes the steps of catalyst preparation, terpinene-4-ol synthesis and the like are disclosed in the present invention. The preparation method includes the following steps: firstly, preparing a mixed colloid of TiO2 and SiO2 by using a sol-gel method, and then centrifuging, washing, drying and roasting is performed to prepare a TiO2—SiO2 binary oxide; then, preparing Ni/TiO2-SiO2 by dipping in a nickel nitrate solution, and preparing a supported catalyst by drying and roasting; and finally, adopting a terpinolene-4, 8-epoxide a raw material, carrying out isomerization under the dual catalytic action of TiO2-SiO2 and Ni of the supported catalyst, and carrying out hydrogenation to prepare terpinene-4-ol. The preparation method can combine isomerization and hydrogenation reaction on the same catalyst, has good selectivity on terpinene-4-ol, and is simple to operate and high in product yield.
