- isopropenyl carborane 异丙烯基碳硼烷
- As a result, carborane acids can add hydrogen ions to weakly basic molecules without destroying the often delicate positively charged molecules that are formed. 而由于超强酸的酸性和腐蚀性强的出奇,所以过去一些极难或根本无法实现的化学反应,在超强酸的条件下便能顺利进行。
- Improvement of synthesis process of methyl isopropenyl ketone was introduced,and the yields in different temperature was compared. 对甲基异丙烯基酮的合成工艺进行了改进,比较了在不同温度下,对醇酮中间体和脱水反应收率的影响。
- The strong-yet-gentle carborane acids overcome this difficulty, allowing chemists to take a closer look at important molecules whose existence was typically fleeting, Reed said. 这种化合物酸性强度是浓硫酸的100万倍,令人惊奇的是,尽管酸性很强,但其腐蚀性却很低,可以在玻璃容器中保存。
- Isopropenyl acetate was synthesized from ketene and acetone by direct esterification using strong acidic cation-exchange resin to substitute H2SO4 as catalyst. 以乙烯酮和丙酮为原料,用强酸性离子交换树脂代替浓硫酸作为催化剂,直接酯化合成乙酰丙酮的中间体乙酸异丙烯酯。
