专利号:US-5538618-A 优先权日:1993-06-17 标 题:Process for the electrochemical synthesis of organosilicon compounds, and an appliance for carrying out the process, and use thereof for preparing organosilicon compounds 发明人:HENGGE EDWIN; JAMMEGG CHRISTA; KALCHAUER WILFRIED 权利人:WACKER CHEMIE GMBH 摘要:A process is described for the electrochemical preparation of organosilicon compounds having at least one SiC-bound organic radical, a solution which contains at least one halosilane being subjected to an electrochemical reaction, an anode which contains a noble metal or an alloy consisting essentially of one or more noble metals having a halogen scavenger flowing around said anode.
专利号:US-2022355262-A1 优先权日:2019-07-22 标题 :System and method for manufacturing water-based hydrophobic aerogels and aerogel composites 发明人:SACHITHANADAM MAHESH; KHORASGANI SOGHRATI ELMIRA; NATARAJAN GAYATHRI 权利人:KROSSLINKER PTE LTD 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.

参考标题:Synthesis, Structure, And Chemistry Of New, Mixed Group 14 And 16 Heterocycles: Nucleophile-Induced Ring Contraction Of Mesocyclic Dications 作者:Eric Block,Evgeny V. Dikarev,Richard S. Glass,Jin,Bo Li,Xiaojie Li,Shao-Zhong Zhang |发布日期:2006.11.1 摘要:More Than 40 New 4- To 12-Membered Ring Heterocycles Containing Various Combinations Of Group 14 And 16 Elements Si, Sn, S, Se, And Te Have Been Synthesized And Fully Characterized. Synthesis Of These Small-Ring As Well As Medium-Ring (Mesocyclic) Heterocycles From Alpha,Omega-Dihalides Is Facilitated By The Presence Of Gem-Dialkylsilyl And Gem-Dialkylstannyl Groups In The Precursors.
