润滑油添加剂的中试研究是实现实验室成果向工业化转化的重要过程，中试研究目的是验证和完善实验室确定的反应条件，为工业化设计提供数据。完善中试装置，提高自动控制技术，建立中试基地是润滑油添加剂中试研究的发展方向。

浩瀚色谱（山东）应用技术开发有限公司采用气相色谱法检测硫化烷基酚钙中的乙二醇含量,并利用外标法,建立了乙二醇质量浓度与平均峰面积的标准曲线,结果表明,乙二醇质量浓度与相应的峰面积有很好的线性关系,由此可以定量定性分析硫化烷基酚钙等润滑油添加剂中乙二醇的含量,从而有效避免在使用过程中因乙二醇含量过多而积累形成的沉淀对发动机造成不同程度的磨损。

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.
