Embodiment 1
[0018] A preparation method of a high-temperature lubricant, comprising the following steps: 1. Synthesis of 1-chloroacetone: successively add 5 g of calcium carbonate and 15 ml of acetone in a 250 ml three-necked flask, and fully shake it at a heating temperature of 60° C. Mix evenly, install a condenser tube on the top of the three-necked flask, the other side of the condenser tube is connected to a device for absorbing chlorine gas, the chlorine gas is absorbed with 5% sodium hydroxide, and the center of the device is connected with a gas collecting bottle for concentrated sulfuric acid for drying. The other end of the gas collecting bottle is connected to a round bottom flask filled with manganese dioxide, and the upper end of the round bottom flask is connected to a separatory funnel filled with concentrated hydrochloric acid, which decomposes chlorine gas at a high temperature of 80°C, and passes chlorine gas into the three-necked flask three times. After one hour, collec...
Embodiment 2
[0021] A kind of preparation method of high-temperature lubricant, it is characterized in that: comprise the following steps: 1, the synthesis of 1-chloroacetone: add 10g calcium carbonate and 20ml acetone successively in the three-neck flask of 250ml, under heating temperature 60 ℃, fully After shaking, make it mix evenly, install a condenser tube above the three-necked flask, and connect the other side of the condenser tube with a device for absorbing chlorine gas. The chlorine gas is absorbed by sodium hydroxide with a capacity of 5%. Gas collecting bottle, the other end of the gas collecting bottle is connected with a round bottom flask filled with manganese dioxide, and the upper end of the round bottom flask is connected with a separatory funnel filled with concentrated hydrochloric acid, which decomposes chlorine gas at a high temperature of 80°C and sends it to the three-necked flask After 3 hours of passing through the chlorine gas, collect the finished product, filter...
