It was obtained from ethylenediamine,ethenesulfonic sodium and decanoic acid as primary materials through addition and acylation.
采用乙二胺、乙烯磺酸钠和癸酸等为主要原料,在低温常压下,经过加成、酰化等反应,合成了一种新的Gem in i(双子)表面活性剂——N,N’-双癸酰基乙二胺二乙磺酸钠,以1H NMR和IR进行结构表征,考察了原料的物料比、反应温度、反应时间等工艺条件对产物收率的影响。
Effects of pH and temperature on inhibition of capric acid to anaerobic granular sludge;
pH、温度和癸酸对厌氧颗粒污泥产甲烷毒性关系的研究
The eutectic mixtures of capric acid(CA) and stearic acid(SA) were prepared by ultrasonic method.
用差示扫描量热仪(DSC)分析研究了癸酸(CA)/硬脂酸(SA)二元混合物的热性能,结果表明,CA-SA合金没有一个确定的低共熔点,只有一个配比范围,并用IR和DSC对81%CA-SA二元混合物经180次加速冷热循环前后的分子结构和热性能进行对比研究,分析表明,此共熔物的分子结构没有发生变化,相变温度和相变焓变化较小,热性能稳定,适合作为相变储能材料。
The result showed that capric acid was sealed effectively in between the layers of montmorillonite and the composite materials were a new type of nano-composite materials for energy storage having obvious energy storage and shape-stabilized characteristics during .
