anhydrous CH2CI2,and treated with a Lewis acid, e.g., TiCl4 at about -60°C to 0°C, preferably at about -25°Cf under a dry, inert atmosphere, e.g. argon. A tertiary amine base such as TMEDA is added and the mixture stirred at about -60°C to 0°C, 正在翻译,请等待...[...
摘要: The invention relates to highly active spherical metal support catalysts with a metal content of 10 to 70% by mass, and a process for their production with the use of a mixture of polysaccharides and at least one metal compound which is dropped into a metal salt solution....
The method for producing a mineral-rich mixture (1), which is made of a mixture carrier and a compound, comprises producing an aqueous suspension of a compound by adding water (5) and mixing with a dry compound that is formed from inorganic hydraulic binder (2), earth alkali smectites (...
Microglia are important immune cells in the central nervous system (CNS) that undergo turnover throughout the lifespan. If microglial debris is not removed in a timely manner, accumulated debris may influence CNS function. Clearance of microglial debris
