潤滑油添加劑的中試研究是實現(xiàn)實驗室成果向工業(yè)化轉(zhuǎn)化的重要過程，中試研究目的是驗證和完善實驗室確定的反應(yīng)條件，為工業(yè)化設(shè)計提供數(shù)據(jù)。完善中試裝置，提高自動控制技術(shù)，建立中試基地是潤滑油添加劑中試研究的發(fā)展方向。

浩瀚色譜（山東）應(yīng)用技術(shù)開發(fā)有限公司采用氣相色譜法檢測硫化烷基酚鈣中的乙二醇含量,并利用外標(biāo)法,建立了乙二醇質(zhì)量濃度與平均峰面積的標(biāo)準(zhǔn)曲線,結(jié)果表明,乙二醇質(zhì)量濃度與相應(yīng)的峰面積有很好的線性關(guān)系,由此可以定量定性分析硫化烷基酚鈣等潤滑油添加劑中乙二醇的含量,從而有效避免在使用過程中因乙二醇含量過多而積累形成的沉淀對發(fā)動機(jī)造成不同程度的磨損。

The pilot-scale research of lubricant additives is an important process to realize the transformation of laboratory results to industrialization. The purpose of the pilot-scale research is to verify and improve the reaction conditions determined by the laboratory and provide data for industrialized design. To improve the pilot plant, improve the automatic control technology, and establish a pilot base is the development direction of the pilot study of lubricant additives.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. used gas chromatography to detect the content of ethylene glycol in calcium sulfide alkylphenol, and established a standard curve of ethylene glycol mass concentration and average peak area using external standard method. , The mass concentration of ethylene glycol has a good linear relationship with the corresponding peak area, which can quantitatively and qualitatively analyze the content of ethylene glycol in lubricating oil additives such as calcium sulfide alkylphenate, so as to effectively avoid the use of ethylene glycol during use. Excessive alcohol content and accumulation of precipitates cause varying degrees of wear on the engine.
