Oil in the use, storage and transportation and other processes will be due to leakage, splash, evaporation, packaging supplies, residual, and other reasons to abandon the cause of the environment into the environment. According to incomplete statistics, around the world each year about 500 ~ 1 000 million tons of petroleum based chemicals into the biosphere, even in the lubricant recycling utilization rate is high (greater than 60%) of countries, there are still 4% ~ 10% of the lubricating oil into the environment, only the EU each year about 60 million tons
Tengzhou City Xiangying Analysis Technology Co., Ltd. was established XiangyingGC7990plus high temperature gas phase chromatography rapid analysis of palm oil fatty acid methyl ester (fatty acid methyl ester, fame) ester exchange reaction in the sample trimethylolpropane fatty acid esters (trimethylolpropane fatty acid has been found. TFATE) method. The Using capillary column (15 m x 250 m x 0.1 M), column temperature conditions: initial temperature of 50 DEG and 50 DEG C / min rose to 220 DEG C, to 30 DEG C / min rose to 290 DEG C, to 40 DEG C / min rose to 330 DEG C for 2 min retention, to 30 DEG C / min rose to 370 DEG C retained 3 min; carrier gas for high purity nitrogen, inlet 380 DEG C, FID detector 400 DEG C, shunt ratio of 20: 1, the sample size for 1 U L. The standard sample of TFATE was prepared, and the purity of the standard sample was verified. The standard curve of TFATE was established. The peak area of the mg/mL in the range of mass concentration was 0.5 ~ 20 and the linear relationship between the peak area and the mass concentration was good. The recovery test showed that the average recovery rate was between 98.06% and 96.64%, and RSD was between 0.45% and 0.20%. The method had good precision and repeatability.
润滑油在使用、储存和运输等过程中会因泄露、飞溅、蒸发、包装用品中的残留、抛弃不当等原因进入环境。据不完全统计,全世界每年约有500～1 000万吨石油基化学品进入生物圈,即使在润滑剂回收利用率较高(大于60%)的国家,仍有4%～10%的润滑油进入环境,仅欧盟每年约有60万吨
滕州市翔鹰分析技术有限公司建立了XiangyingGC7990plus高温气相色谱快速分析棕榈油脂肪酸甲酯(fatty acid methyl ester,FAME)酯交换反应样品中三羟甲基丙烷脂肪酸三酯(trimethylolpropane fatty acid trimester,TFATE)的方法。采用毛细管柱(15 m×250μm×0.1μm),柱温条件为:起始温度50℃,以50℃/min升至220℃,以30℃/min升至290℃,以40℃/min升至330℃保留2 min,以30℃/min升至370℃保留3 min;载气为高纯氮气,进样口380℃,FID检测器400℃,分流比20∶1,进样量为1μL。制备了TFATE的标准样品,并验证了标准样品的纯度,建立了TFATE的标准曲线,在质量浓度范围0.5～20.0 mg/mL内峰面积与被测物质量浓度线性关系良好。加样回收试验表明,平均加样回收率在96.64%～98.06%之间,RSD在0.20%～0.45%之间,该方法有较好的精密度和重复性。
