Abstract:
1. A process for attaching a modifying agent to a substrate surface, the process comprising the steps of: A. Contacting in an open contact zone and under a flow of inert gas a substrate that has a BET surface area of less than one square meter per gram (m B. Closing the contact zone and stopping the flow of inert gas to the contact zone; C. Agitating the substrate mixture under the inert gas in the closed contact zone to commence evaporation of the liquid mixing agent; D. Reducing the temperature and pressure of the closed contact zone while continuing to agitate the substrate mixture; and E. Completing the substantial evaporation of the mixing agent from the substrate mixture by opening the contact zone and initiating an inert gas flow while continuing agitation of the substrate mixture and maintaining a reduced pressure.
