Embodiment
[0200] Hereinafter, although an Example demonstrates this invention more concretely, this invention is not limited to each Example. In addition, in the figure, for the sake of simplicity, "weight%" is marked as "wt%", and only the serial number and symbol of the lubricant composition are indicated.
[0201] [Measurement of properties of lubricant composition]
[0202] Various properties of the lubricant composition were measured by the following methods.
[0203]
[0204] Evaporation loss was measured by an evaporation test at 180°C. Specifically, put 2 g of the lubricant composition into a cylindrical test container made of SUS304, with an inner diameter of 20 mm and a height of 35 mm, and place the cylindrical test container in a constant temperature tank with a rotating disk at 180 ° C. After standing in the medium for a specified time, the weight of the lubricant composition is measured. The evaporation loss was obtained by the following formula. And, the average val...
manufacture example 1
[0220] [Production Example 1: Production of Compound 1]
[0221] Put 1046g of 2-ethylhexyloxyethylethanol, 230g of 1,6-dichlorohexane, and 219g of potassium hydroxide into a 2-liter glass flask, and stir at 180°C for 1 hour to make them react . Thereafter, the reaction solution was cooled to room temperature, and hydrochloric acid was added to neutralize excess alkali. After washing the reaction solution with 2 liters of water, the organic layer was separated and taken out using a separatory funnel, and Compound 1 was isolated from the organic layer by vacuum distillation. The obtained compound 1 1 H-NMR table as Figure 8 shown.

[0222] [Production Example 2: Production of Compound 2]
[0223] 1310 g of 2-(2-ethylhexyloxy) ethyl ethanol, 3048 g of 1,4-dichlorobutane, and 438 g of potassium hydroxide were charged into a 10-liter glass flask, stirred at 90° C. for 16 hours, make it react. Thereafter, the reaction solution was cooled to room temperature, and hydrochloric acid was added to neutralize excess alkali. After washing the reaction solution with 3 liters of water, the organic layer was separated and taken out using a separatory funnel, and 4-[2-(2-ethylhexyloxy)ethoxy] was separated from the organic layer by vacuum distillation. -Butyl chloride. Then, 2158 g of 2-butyl octanol, 1185 g of 4-[2-(2-ethylhexyloxy)ethoxy]-butyl chloride, 282 g of potassium hydroxide were charged into a 5-liter glass flask , stirred at 180°C for 5 hours to make it react. Thereafter, the reaction solution was cooled to room temperature, and hydrochloric acid was added to neutralize excess alkali. After washing the ...
