The results in-dicate that the loss of aβ-hydrogen from 2-hydroxyethyl radical to yield vinyl alcohol and that a 1,3-hydrogen shift to form ethoxy radical have close A factors and rate constants.
用量子化学结果和Eyring过渡态理论计算了200-1200K温度范围内,标题反应的A因子和速度常数,结果表明,2-羟乙基脱去β-H生成乙烯醇与其经[1,3]重排生成乙氧基有相近的A因子和速度常数,且常温下速度较慢,反应难以进行。
It was discussed that the main factors having effect on the vulcanization time of RTV block methyl silicone rubber, such as the mol ratio of ethoxyl and silicone hydroxyl, the pH value of methyltriethoxysilane, and the content of iron ions impurity in methyltriethoxysilane, temperature, moisture, and the quantity of catalyst.
讨论了影响甲基嵌段室温硫化硅橡胶硫化时间的主要因素,如:乙氧基与硅羟基的量之比,甲基三乙氧基硅烷低聚物的pH值、铁离子的含量,以及温度、湿度和催化剂的用量等;并介绍了预防和控制这些影响因素的方法。
