The paper presents the sol-gel synthesis of porous silica monolith in the presence of cetyltrimethylammonium bromide and polyethylene glycol. Parameters of the porous structure and mechanical properties of silica monolith are varied by the reaction mixture composition and reprecipitation and thermal treatment conditions. Mechanical properties and permeability of obtained material are investigated and optimal parameters are identified for the synthesis of porous silica monolith for flow reactors.
