Method for the producing of mesoporous materials was developed among the intermediate process in the synthesis of smectites. The product made from a Si-Mg hydrous oxide by hydrothermal treatment at relatively low temperature has the properties of porous materials with micro and mesopores. This material can be transformed into a mesoporous material having sharp pore size distribution about 40Å by the intercalation of large organic ions and by heating to remove the organic substances. The mesoporous material is, therefore, expected to be applied in various industrial fields such as separation of organic molecules like methyl derivatives of tocol.
