ABSTRACT:
A method for chlorinating a clay mineral starting composition to produce reactive chloride intermediates, comprising: reacting said composition in substantially dry particulate form with gaseous SiCl.sub.4 to activate the surface of said composition, thereby forming said reactive chloride intermediate, said reaction being conducted at temperatures below that at which volatilization or dehydration of the starting composition will occur. The resulting compounds are highly reactive intermediates, which can then be functionalized by reaction with a large group of organics, or organic derivatives.
