The present invention provides an amphiphilic molecular sieve containing a hydrophilic group on the outside and a lipophilic group on the inside and a production method thereof. The production method comprises: dispersing the ZSM-5 spherical nano-molecular sieve into toluene, adding thereto an organosilane containing a hydrophilic group and reacting at 40-80&#xb0; C. for 2-16 h, to obtain a molecular sieve containing a hydrophilic group; placing the molecular sieve containing a hydrophilic group in an aqueous solution of sodium hydroxide and reacting at 50-90&#xb0; C. for 10-50 min, to obtain a molecular sieve containing a hydrophilic group on the outside; dispersing the molecular sieve containing a hydrophilic group on the outside into toluene, adding thereto an organosilane containing a lipophilic group and reacting at 40-80&#xb0; C. for 2-12 h, to obtain the amphiphilic molecular sieve containing a hydrophilic group on the outside and a lipophilic group on the inside. The present invention also provides an amphiphilic molecular sieve obtained by the above production method, which contains a hydrophilic group on the outside and a lipophilic group on the inside.

The present invention provides a nano-silica dispersion having amphiphilic properties and a double-particle structure and its production method. The production method comprises: producing a lipophilically modified nano-silica alcosol which is denoted as a first reaction solution by adding a silane coupling agent containing a lipophilic group to a nano-silica alcosol as a raw material; producing a hydrophilically modified nano-silica alcosol which is denoted as a second reaction solution by adding a silane coupling agent containing a hydrophilic group into a nano-silica alcosol as a raw material; producing the nano-silica dispersion having amphiphilic properties and a double-particle structure by adding 3-aminopropyltriethoxysilane to the first reaction solution, stirring, then mixing the resultant with the second reaction solution. The present invention further provides a nano-silica dispersion having amphiphilic properties and a double-particle structure produced by the above production method. It has both hydrophilic and lipophilic properties, and has the double-particle structure, with a particle size of less than 100 nm. The production process is simple and low in cost.
