Isoamyl hexanoate could be synthesized using stannic chloride from caproic acid and isoamyl alcohol. 研究了用四氯化锡催化己酸和异戊醇合成己酸异戊酯的反应。
It has been de-termined by X-ray photoelectron spectroscopy ( XPS or ESCA) that the colou-ring material in pores of anodic coating on aluminum exists in the forms of tin metal and α-stannic acid. 用x光电子能谱法(XPS或ESCA)确定了着色物质是以金属锡和α锡酸的形式存在;
It is found out that the plasma treatment makes the stannic acid gel fill in the inner part of the silk fibers easily and improves the weighting ability of the silk fibers, which indicates that the microvoids appear in the silk fibers. 发现等离子处理有利于锡酸胶体填埋进真丝纤维内部,使真丝纤维的增重能力提高,证明真丝纤维内部生成了微孔穴。
Weighting properties of the mulberry silk fibers after the low temperature oxygen treatment are also studied. Stannic acid is used to characterize the microvoids in the silk fibers. 研究了低温氧等离子处理后真丝纤维的增重特性,并用锡酸法表征了等离子处理后真丝纤维的填埋能力。
The catalytic mechanism of stannic chloride/ strong carboxylic acid co-catalyst system in the cationic ring-opening/ polymerization of epichlorohydrin is present. 并提出了四氯化锡/强羧酸共催化体系催化环氧氯丙烷阳离子开环聚合的机理。
The aggregate structure of silk fiber treated with plasma changes and crystalline degree of it decrease after stannic acid weighting treatment. 经等离子体-锡酸增重处理后聚集态结构发生了改变,结晶度下降。
