Embodiment 1

[0028] (1) Isomerization etherification ring-opening reaction: Weigh 90.0g of methanol and 9g of D001 resin supported by cerium sulfate as a solid catalyst (D001(Ce 4+ )) placed in a four-necked flask with a condenser, agitator and a thermometer, stirred, refluxed, and temperature controlled at 35°C, then added 300g of epoxy biodiesel, the epoxy value of which was 5.48, and opened at this temperature Ring reaction, the ultrasonic frequency of the auxiliary ultrasonic equipment is 40KHZ, and the ultrasonic power is 500W. During the reaction process, samples were taken from the four-necked flask every 10 minutes, and the epoxy value was measured. When the epoxy value was less than 0.1, it was the end of the reaction. When the reaction reaches the end point, stop the reaction, cool the reaction mixture to room temperature, wash with distilled water at 40°C, separate the lower aqueous phase and solid catalyst and recover the solid catalyst; then wash the upper organic phase with a...

Abstract

The invention aims at solving the defects of long reaction time and high reaction temperature of a heterogeneous etherification ring-opening reaction of epoxy biodiesel of prior arts, and provides a method for preparing biological lubricating oil base oil by using epoxy biodiesel. The method comprises the steps that: (1) under a condition of ultrasonic-assisted heat and mass transfer, the heterogeneous etherification ring-opening reaction is carried out, wherein long-chain fatty alcohol and a metal-ion-load-type cation exchange resin solid catalyst are mixed and heated to a reaction temperature; epoxy biodiesel is added for carrying out the ring-opening reaction; when an epoxy value is smaller than 0.1, the reaction is stopped; the reaction mixture is cooled to room temperature, and is washed by using distilled water; a lower-layer aqueous phase and the solid catalyst are separated, and the solid catalyst is recovered; an upper-layer organic phase is washed to neutral; and vacuum dehydration and light component removing are carried out, such that isomerized fatty alcohol ether is obtained; and (2) the product obtained in the step (1) is subjected to clay discoloration, such that clear and transparent biological lubricating oil base oil is obtained. According to the adopted catalyst, the catalytic active agent has high selectivity.

Description

technical field [0001] The invention belongs to the field of bio-lubricating oil preparation, in particular to a method for preparing bio-lubricating oil base oil from epoxy biodiesel. Background technique [0002] With the improvement of people's awareness of environmental protection and the emphasis on the development of renewable energy technology, the environmental problems caused by lubricating oil have also attracted widespread attention. It has become an important issue to find a green and environmentally friendly lubricating oil base oil that can replace mineral oil. Vegetable oil has good degradability and strong renewability, and is currently the main researched environment-friendly lubricating oil. However, vegetable oil has poor thermal oxidation stability and low temperature fluidity. In order to solve these two problems, vegetable oil can be chemically modified. The most economical and effective modification method is epoxidation-ring-opening series modificatio...
