Description

technical field

[0001] The invention relates to the technical field of catalysts, in particular to a Ni catalyst for the production of cyclohexane-1,2-dioctyl 2 The preparation method of P / NC catalyst, Ni 2 P / NC catalyst and its application. Background technique

[0002] Dioctyl phthalate is a colorless or light yellow oily transparent liquid, soluble in most organic solvents and hydrocarbons, slightly soluble in glycerin and ethylene glycol, and has good compatibility with most industrial resins , is a common industrial raw material. Dioctyl cyclohexane-1,2-dicarboxylate is an environmentally friendly non-phthalate plasticizer, it has a structure similar to dioctyl phthalate, and has the The performance of ester, and the function is more excellent. The specific performance is: Dioctyl cyclohexane-1,2-dicarboxylate has little mobility, is colorless and transparent, and is completely environmentally friendly. It can be miscible with common organic solvents and common plas...
