标题 :Process for the synthesis of diaminopyridine and related compounds
发明人：RITTER JOACHIM C
权利人:DU PONT; RITTER JOACHIM C
摘要:A process is provided for the synthesis of a diaminopyridine, such as 2,6-diaminopyridine and related compounds, which are used industrially as compounds and as components in the synthesis of a variety of useful materials. The synthesis proceeds by means of a chlorine-ammonia displacement in the presence of a copper source.

权利人:MILLIKEN & CO
摘要:This invention relates to the in-situ synthesis of multi-core electroconductive powders. The multi-core ECPs of the present invention are made using an in-situ synthesis method which eliminates the need for combining mixtures of various types of single-core ECPs in order to achieve the desired end-use product. The multi-core ECPs described herein exhibit very little coloration. They also exhibit low electrical resistivity and contain reduced amounts of antimony.

标题 :A method for synthesis of carbon-silica-metal composite and combination thereof
发明人：P R RAMKUMAR
权利人:P R RAMKUMAR; ANNA UNIV CHENNAI
摘要:The present invention is a facile and template based synthesis method for carbon-5 silica xerogel or carbon-silica aerogel type composites with uniformly distributed metal or metal oxide nanoparticles embedded inside their structure. The method gives high yield with almost all the synthesized metal or metal oxide nanoparticles loaded into the carbon-silica xerogel or carbon-silica aerogel composite structure by in-situ one-pot synthesis procedure. Embedded metal or metal-oxide 10 nanoparticles are three dimensionally covered by carbon coating. This method can also be used to produce carbon-silica xerogel or carbon-silica aerogel composite template based novel hollow granular shell carbon xerogel or hollow granular shell carbon aerogel with highest specific surface area. This method can also be scaled to large amount for various products through one line of synthesis process, 15 showing the potential for industrial scale prospects.
