The vesicles are shown to be effective as delivery agents for chemical and biological agents. They are also shown to be useful in methods of treatment and as components of an immunogenic composition.
专利号:US-6172251-B1 优先权日:1998-07-24 标题:Solid/liquid phase transfer system 发明人:PARKER DANE KENTON 权利人:GOODYEAR TIRE & RUBBER 摘要:The present invention discloses a technique for reacting a first liquid chemical compound with a second liquid chemical compound which comprises (1) supporting the first liquid chemical compound on a solid support; (2) subsequently bringing the solid support into contact with the second liquid chemical compound; and (3) allowing the first chemical compound to react with the second chemical compound in the presence of a phase transfer catalyst to produce a reaction product. This technique is particularly useful in the synthesis of sulfur containing organosilicon compounds of the formula Z-Alk-Sn-Alk-Z wherein Z is selected from the group consisting ofwherein R1 is an alkyl group of 1 to 4 carbon atoms, cyclohexyl or phenyl; wherein R2 is alkoxy group of 1 to 8 carbon atoms, cycloalkoxy group of 5 to 8 carbon atoms or an alkylmercapto group of 1 to 8 carbon atoms; wherein Alk is a divalent hydrocarbon of 1 to 18 carbon atoms; and wherein n is an integer of 2 to 8. For instance, such sulfur containing organosilicon compounds can be made by reacting aqueous solutions of various polysulfidic anions in saturated sodium chloride brine solutions with chloropropyltriethoxysilane (CPTES) supported on carbon black in the presence of a phase transfer catalyst.

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.
