聚三醇在合成金属加工液中的作用

近年来，合成金属加工液或冷却剂的发展都很快，其所含的组分都可以溶解于水，不仅具有比较长的使用寿命和比较高的冷却效果，而且具有比许多乳化的金属加工液或油溶的金属加工液更强的去垢力。聚二醇在合成金属加工液中通常被用作润滑添加剂，它是环氧乙烷(简称EO)和氧化丙烯(简称PO)的共聚物。聚二醇具有很好的润滑性能，这在齿轮油、液压油以及压缩机等领域中均已得到证明。在合成金属加工液中，聚二醇表现出可逆的溶解性，即在常温下是水溶性的，而升高温度后它又可以变成非水溶性的。聚二醇的逆溶解性的重要性及其与阴离子极压添加剂之间的协同效应将从成型和机加工过程的数据中得到解释和证实。

Synthetic lubricants based on sebacic complex esters

This paper presents the results of a study carried out in order to produce synthetic ester oils of a mixed structure based on sebacic acid with beneficial tribological properties. These series of unsymmetrical diesters were synthesized using superior aliphatic alcohols such as 2‐ethyl‐hexanol, isodecanol and isotridecanol, along with special alcohols of a complex alkyl‐aryl structure, namely 2‐phenoxy‐ethanol, 2‐[(o‐sec butyl) phenoxy] ethanol and 2‐[(p‐nonyl) phenoxy] ethanol. Also synthesized were symmetric esters based on the complex aliphatic‐aromatic alcohols with pendant aliphatic chain. The variation in the principal properties as a function of both the length of the aliphatic chain introduced by the aliphatic alcohol, and the length and position of the aliphatic pendant chain on the aromatic nucleus of the complex alkyl‐aryl alcohol was assessed. Based on this, it has been possible to obtain fluid products with variable properties. The introduction of the aromatic function in the structure of these diesters led to interesting features, and the superior values recorded for the main tribological characteristics demonstrated their versatility.

阴离子交换色谱中色谱柱温度对C1～C5脂肪酸保留的影响

研究了直接电导检测阴离子交换色谱中柱温对C1～C5脂肪酸保留的影响。实验采用Shim—packIC—A3阴离子交换柱,分别以邻苯二甲酸氢钾和对羟基苯甲酸-Tris-硼酸为流动相,柱温控制在25～50℃。在两种流动相下,脂肪酸的保留行为均表现为吸热行为．即随温度升高,保留增强。两种流动相相比,以对羟基苯甲酸-Tris-硼酸为流动相时,温度对脂肪酸保留的影响更明显。C1-C5脂肪酸的范特霍夫曲线具有良好的线性关系。通过改变柱温可以改善脂肪酸的色谱峰形和分离。     

A High-Performance Multifunctional Lubricant Additive for Water–Glycol Hydraulic Fluid

A water-soluble boron (B)-containing thiophosphite derivative (BTP) was synthesized, and its tribological, anticorrosion, and antirust properties as an additive for the base liquid of water–glycol hydraulic fluid were evaluated in detail. The results of tests demonstrated that BTP is indeed a high-performance and multifunctional water-soluble lubricant additive that was able to remarkably improve the extreme pressure, friction-reducing, antiwear, anticorrosion, and rust-inhibiting properties of the base liquid when added at a low adding concentration (<3 wt%). Based on a performance comparison of BTP and thiophosphite (TP), whose chemical structure is similar to that of BTP but without B, a number of primary conclusions were drawn. The B element existing as alkanolamine borate group could greatly improve the extreme pressure, antiwear, and antirust performance of BTP, especially the antirust performance, but had only a small effect on the friction-reducing and anticorrosion properties. Based on characterizations and analyses of the worn surfaces, we propose that the antiwear mechanism consists of the prepared compound BTP reacting with the steel surface during the friction process to generate a protective film mainly composed of phosphate, sulfide, sulfate, organic amine, and B₂O₃.
