本文建立了反相高效液相色谱-荧光检测方法分析水基金属加工液中壬基酚聚氧乙烯醚的方法。高效液相色谱采用ZORBAX Eclipse XDBC-18色谱柱,甲醇-水-乙腈(75+20+5,体积比)为流动相,荧光检测器激发波长为230 nm,发射波长为296 nm,水基金属加工液样品经甲醇超声萃取处理后进入色谱分析。结果表明,壬基酚聚氧乙烯醚在5~200 mg/L浓度范围内呈良好线性,线性相关系数为0.9997,水基金属加工液样品加标回收率为95.6%~108.6%,相对标准偏差小于3.00%,壬基酚聚氧乙烯醚检测限可达0.58 mg/L。该方法适合用于水基金属加工液中的壬基酚聚氧乙烯醚的定量分析。 相似文献

由纳米TiN颗粒、水基液以及分散剂可制备得一种水基纳米TiN流体的溶液,并针对不同制备条件下溶液中纳米颗粒在水基液中的分散稳定性进行了研究.通过改变实验制备过程中机械搅拌和超声波分散时间、分散介质水基液的种类、分散剂的质量分数,制备出不同分散程度的溶液,然后采用沉降稳定性分析和流变特性分析对得到的溶液进行分散稳定性的评价分析.结果表明,上述因素均会对溶液的分散稳定性有一定程度的影响.过短的搅拌分散时间不利于纳米TiN流体介质中颗粒的分散;在不同分散介质中分散时,去离子水的分散效果最佳;适量质量分数的分散剂可以改善纳米流体的分散稳定性.基于上述分析提出了纳米TiN颗粒在水基液中的分散理论. 相似文献

A number of esters were prepared from the reaction of acid chlorides with ricinoleic acid polymers and screened for anti-rust
properties and antimicrobial activity in spent coolants of water-based cutting fluids. Aqueous solutions of triethanolamine
salts with decanoic acid, undecanoic acid and oleic acid esters of ricinoleic acid dimer, trimer, tetramer and hexamer showed
good anti-rust properties for water-based cutting fluids. Dehydrates of ricinoleic acid polymers also showed good anti-rust
properties for water-based cutting fluids. 相似文献

A number of half esters were prepared from the reaction of alcohols with dimer acids and screened for anti-rust properties
and antimicrobial activity in spent coolants of water-based cutting fluids. Aqueous solutions of triethanolamine salts with
lower-alcohol half esters of dimer acid showed good anti-rust properties for water-based cutting fluids. 相似文献

A number of N,N′-diacylalkyldiamines were prepared from the reaction of acid chlorides with 1,8-diaminooctane and 1,12-diaminododecane
and screened for anti-rust properties and antimicrobial activity in spent coolants of water-based cutting fluids. Aqueous
solutions of N,N′-dihexanoyl-1,8-diaminooctane and N,N′-isobutyroyl-1,12-diaminododecane showed good anti-rust properties
for water-based cutting fluids. Aqueous emulsions of N,N′-dibutyroyl-, dipentanoyl-, dihexanoyl- and dioctanoyl-1,12-diaminododecane
showed good lubricities and antimicrobial activity for water-based cutting fluids. 相似文献

According to the conventional evaluation methods of drilling fluids, the inhibitive property of polyoxyalkyleneamine (POAM), which was prepared in the laboratory, to sodium montmorillonite (Na-MMT) was investigated, and the shale cuttings recovery ratio and the rheological properties of drilling fluids were measured before and after adding POAM in several water-based drilling fluids. The results showed that POAM was completely water-soluble, exhibited the superior performance to inhibit the hydration of Na-MMT and reduced the swelling or hydration of shale cuttings effectively. In addition, the determination of the biological toxicity and compatibility of POAM indicated that POAM was low toxic and compatible with other common drilling fluid additives. 相似文献
