【正文】 hese were thus some of the initial examples of anometallic chemistry (one of the most studied branches of inanic chemistry today). Cp*2Mg (Cp*Na?THF)? 主族金屬有機(jī)化學(xué) This process is still operated today with only minor modifications and is called Rochow Process or Direct Process. The silicones are made by hydrolysis of R2SiCl2 The by product HCl is recovered, and, after oxidation to Cl2, used to make the chlorinated starting materials of the process. Among industrial processes, the Rochow Process has now one of the highest recovery rates of products ( %). ? When Rochow added the water, he made his methyl silicone: ? n(9) + nH2O n[(CH3)2SiO]n + nHCl ? In 1940, Eugene Rochow demonstrated a one step method to make silicone polymers. Much more would need to be done to make Rochow39。最典型的例子就是固態(tài)甲基鋰。并加以評論。因此與 MeLi不同，t?BuLi可溶于非極性溶劑中，并且在70?C/1mbar的條件下升華。 H2(g) Group 2: M(s) + 2 H2O(l) ? M+2(aq) + 2 (OH)(aq) + H2(g) These reactions are very exothermic and increase in violenc
