Abstract

The invention discloses a technology for preparing epoxy fatty acid isooctyl ester based on biodiesel. The technology comprises following steps: the biodiesel is taken as a raw material and subjectedto a transesterification reaction with isooctyl alcohol in the presence of a solid base catalyst, after the reaction, isooctyl alcohol is removed by evaporation, crude isooctyl ester is distilled, anddistilled isooctyl ester is obtained; isooctyl ester, formic acid and hydrogen peroxide are subjected to an epoxidation reaction, layering, washing and flash evaporation are performed after the reaction, and a high-quality epoxy fatty acid isooctyl ester product is obtained. The technology is efficient and environmentally friendly, conversion rate of oil and fat transesterification is high, the solid catalyst can be repeatedly used, heat is recycled, epoxy wastewater treatment is simple, and the technology is suitable for industrial production. High-quality epoxy fatty acid isooctyl ester canbe produced stably and serves as a green bio-based auxiliary to be widely applied to the fields of plastic processing and the like, additional value of the biodiesel can be increased, and rapid development of the biodiesel industry is promoted.

Description

technical field

[0001] The invention belongs to the technical field of biodiesel downstream product development, in particular to a process for preparing epoxy fatty acid isooctyl ester based on biodiesel. Background technique

[0002] With the vigorous development of the biodiesel industry, the development and synthesis of a series of high value-added chemical products using biodiesel as a platform compound has become a current hot spot. This will not only increase the added value of biodiesel, but also benefit the healthy and sustainable development of the domestic biodiesel industry. Among them, epoxy fatty acid isooctyl ester, as a green and environmentally friendly bio-based additive, has received extensive attention at home and abroad in recent years. It can be used as an environmentally friendly plasticizer, partially or completely replacing phthalate plasticizers (such as DOP, DBP, etc.), and used in the PVC industry; it can also be used as a stabilizer, admixture a...
