The optimum preparation conditions were determined as follows: mass ratio of natural graphite to sulfuric acid, nitric acid and decanol 1 ∶ 3 ∶ 2 ∶ 0.1, reaction time 40 min, and reaction temperature 60 ℃. 确定了可膨胀石墨的最佳制备条件:石墨与硫酸、硝酸、癸醇的质量比为1∶3∶2∶01,反应时间为40min,反应温度60℃。
Abstarct: Menthol and Eucalyptus oil in confection products were determined simultaneously by gas liquid chromatography, with columns packed with 10% carbowax ( polyethyleneglycols) on 80/ 100 mesh diatomite with decanol as internal standard. 利用气相色谱法(GC),以聚乙二醇(10%)涂布的高纯硅藻土(80/100目)为色谱柱载体,采用癸醇为内标,可同步测定糖果中薄荷醇、桉叶油的含量。
The liquid crystal structure between system sds/ decanol/ glycerol and sds/ decanol/ formamide SDS/正癸醇/甘油与SDS/正癸醇/甲酰胺液晶结构
This paper hos studied the synthetic conditions of disodium sulfosuccinate decanol monoester by optimum formulations. Analysed its surfactancy and discussed its applied prospects. 本文用正交试验法对癸醇琥珀酸酯磺酸钠的合成条件进行了优化研究,对其表面化学性能进行了分析测定,并探讨了其应用前景。
The results are as follows: 1. The percolation phenomenon was apparently resisted by toluene in the water/ AOT/ decanol system, while no effect in the water/ AOT/ heptanol system. 结果如下:1.甲苯对水/AOT/癸醇反相微乳液体系电导渗滤有明显的抑制作用,而对水/AOT/庚醇体系没有影响。
