Embodiment 1
[0031] Example 1 Preparation of Organic Rare Earth A
[0032] In a 1.5L flask equipped with a stirrer, add 200ml of water, 335.5g (3.05mol) of thiophenol and 171g (3.05mol) of potassium hydroxide, stir and heat up to 90-95°C for 0.5 hours of constant temperature reaction, then Add 354.4 g (1 mole) of rare earth chloride and react at a constant temperature of 90-95°C for 1.5 hours. Cool to room temperature, filter, wash the solid with water until neutral, and then dry it in a constant temperature oven at 80-90°C to obtain an organic rare earth A compound.
Embodiment 2
[0033] Example 2 Preparation of Organic Rare Earth B
[0034] In a 1.5L flask equipped with a stirrer, add 200ml of water, 379.4g (3.05mol) of p-cresol and 171g (3.05mol) of potassium hydroxide, stir and heat up to 90-95°C for constant temperature reaction 1 Hours, then add 354.4 g (1 mole) of rare earth chloride and react at a constant temperature of 90-95°C for 2 hours. Cool to room temperature, filter, wash the solid with water until neutral, and then dry it in a constant temperature oven at 80-90°C to obtain the organic rare earth B compound.
Embodiment 3-5
[0036] Prepared for synthetic ultra-high temperature chain oils. Examples 3-5 are prepared in the same way except that the composition of raw materials is different. The preparation method is: add base oil, organic rare earth, high-temperature antioxidant, extreme pressure anti-wear additive, rust inhibitor, metal deactivator and detergent dispersant into the mixing container, stir and heat up to 120-130°C, constant temperature stirring and dehydration After 1-1.5 hours, stop heating, stir and cool to 70-80°C, and filter to obtain the product. The composition of each embodiment is shown in Table 1, and the performance analysis results are shown in Table 2.
