Amphiphilic molecular sieve containing hydrophilic group on the outside and lipophilic group on the inside and production method threof

A method of producing an amphiphilic molecular sieve containing a hydrophilic group on the outside and a lipophilic group on the inside, comprising:

• a) producing a ZSM-5 spherical nano-molecular sieve with a diameter of 50-200 nm;
• b) dispersing the ZSM-5 spherical nano-molecular sieve into toluene, adding thereto an organosilane containing a hydrophilic group and reacting at 40-80° C. for 2-16 h, followed by centrifugation, washing and drying, to obtain a molecular sieve containing a hydrophilic group;
• wherein the amount of substance of the toluene is 40-80 times that of the ZSM-5 spherical nano-molecular sieve, and the amount of substance of the organosilane containing a hydrophilic group is 4-8 times that of the ZSM-5 spherical nano-molecular sieve;
• c) placing the molecular sieve containing a hydrophilic group in an aqueous solution of sodium hydroxide and reacting at 50-90° C. for 10-50 min, followed by centrifugation, washing and drying, to obtain a molecular sieve containing a hydrophilic group on the outside;
• and
• d) 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° C. for 2-12 h, followed by centrifugation, washing and drying, to obtain the amphiphilic molecular sieve containing a hydrophilic group on the outside and a lipophilic group on the inside;
• wherein the amount of substance of the toluene is 40-80 times that of the molecular sieve containing a hydrophilic group on the outside, and the amount of substance of the organosilane containing a lipophilic group is 4-8 times that of the molecular sieve containing a hydrophilic group on the outside.
