  • Publication number: 20130251623
    Abstract: The present invention refers to a continuous process for in secco nanomaterial synthesis from the emulsification and detonation of an emulsion. The said process combines the simultaneous emulsification and detonation operations of the emulsion, thus assuring a production yield superior to 100 kg/h. When guaranteeing that the sensitization of the emulsion occurs mainly upon its feeding into the reactor, it is possible to avoid the accumulation of any class-1 substances along the entire synthesis process, thus turning it into an intrinsically safe process. Afterwards, dry collection of the nanomaterial avoids the production of liquid effluents, which are very difficult to process. Given that there's neither accumulation nor resort to explosive substances along the respective stages, the process of the present invention becomes a safe way of obtaining nanomaterial, thus allowing it to be implemented in areas wherein processes with hazardous substance aid are not allowed.

  • Patent number: 8435480
    Abstract: Disclosed herein are a method for synthesizing one-dimensional helical mesoporous structure, in which a self-assembled structure of a glycine-derived surfactant is used as a template at room temperature to synthesize the one-dimensional helical mesoporous silica structures having a uniform pore size and a method for synthesizing a glycine-derived surfactant for synthesizing the helical nanoporous structures, in which relatively expensive surfactant can be easily recovered using an organic solvent and reused, which provides economical and environment friendly effects and the glycine-derived surfactant is synthesized by homogeneously heating a reaction product of glycine and phthalic anhydride by dielectric heating with irradiation of microwave, whereby it is possible to realize high yield of the glycine-derived surfactant, shortened synthesis time and increase in energy efficiency, leading to improvement in productivity and reduction in production cost.
