摘要（英）：

The invention belongs to the technical field of preparation of a cyclohexanes plasticizer by liquid phase hydrogenation of a phthalates plasticizer, and particularly discloses a using method for a catalyst for preparation of a cyclohexanes plasticizer by liquid phase hydrogenation of a phthalates plasticizer. The catalyst is non-load type bi-metal nano microcrystal consisting of an active component and an auxiliary, wherein the active component is one of Ru, Rh, Pt, Pd and Ni; the auxiliary is one of Zn, La, Co, Mn and Ce; and the mass ratio of the auxiliary and the active component is 1-10%. In the using method, the mass ratio of the catalyst and the phthalates plasticizer is 0.25-1.0%, the reaction temperature is 80-120 DEG C, the hydrogen pressure is 2.0-5.0 MPa, and the reaction time is 20-60 min. When the catalyst is used for liquid phase hydrogenation, reaction conditions are mild, the conversion ratio of the phthalates plasticizer is high (99% or above), the selectivity of the cyclohexanes plasticizer is good, industrialization is implemented easily, the economic benefit and the social benefit are good, and the using method has not been reported publically.
