Abstract

Disclosed are processes for preparing sol-gel resins from phenolic compounds and aldehydes. The process includes reacting an hydroxylated benzene and a catalyst with an aldehyde to form a liquid storage stable intermediate. The storage stable intermediate may then be stored for a period of time before being utilized in a process to prepare the sol-gel resin, in either monolith or particle form, by subsequently reacting the intermediate with an hydroxylated benzene and a catalyst.
