摘要:为了理解在式类型rosime的α-硅烷中的si-oc键的增强的反应性方面的硅α-效果2 Ch 2 X相比类似的γ-硅烷rosime 2(ch 2)3 X(r =我等; X =官能团),一个系统的实验和动力学和这样的化合物的水解的机制的计算研究进行.为了这个目的,一系列合适的模型化合物的合成和在cd研究了它们的水解动力学3 Cn / D 2 O在碱性和酸性条件下,使用1H NMR光谱作为分析工具.为了获得有关反应机理的更多信息,实验研究得到了计算研究的补充.这些研究表明,硅α效应不能通过特殊的单一效应来合理化.观测到的反应性实际上是由不同成分的总和产生的,例如电子和空间效应,Pd依赖性以及官能团(甚至是质子化的官能团)与烷氧基离去基团之间的氢键.因此,不应再使用术语"硅α-效应"来解释在有机基的α-或γ-位带有官能团的烷氧基有机基硅烷在硅原子上的水解反应性(所谓的α-或γ-硅烷).

摘要:Embodiments of the present invention provide users with a system and method for manufacturing water-based hydrophobic aerogels and aerogel composites. The system and method can be carried out in a manner which is more rapid than typical ways and can be readily scalable. The method of manufacture is useful for producing water based hydrophobic aerogels and aerogel composites on a large scale with good homogeneity and consistency. Advantageously, the method of manufacture also has the benefit of a shorter processing time due to the vacuum homogenizing and mixing processes, the use of microwave assisted vacuum freeze drying for ease of synthesis of water-based hydrophobic aerogels.
