| description | The invention provides an alkyl germanium compound, a preparation method and application, and the method comprises the following steps: mixing an organic germanium compound and an organic magnesium compound in tetrahydrofuran, carrying out a reflux reaction, adding water and ethyl acetate after the reaction is finished, extracting, combining organic phases, drying with anhydrous sodium sulfate, and concentrating to remove ethyl acetate. A series of high-purity organic germane products are obtained, and the series of organic germane reagents are distilled and purified, so that the purified alkyl germanium compound is obtained. The alkyl germanium provided by the invention can be well dispersed in PAO-10 as an oil-based lubricating additive, and shows excellent friction reduction and wear resistance when being tested on a steel/steel friction pair. Wherein Bu3GeC8 shows the best antifriction and antiwear performance, and meanwhile, the extreme pressure bearing capacity of PAO-10 on a steel/steel friction pair c |
