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

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

• a) producing a nano-ZSM-5 molecular sieve with a diameter of 50-200 nm;
• b) dispersing the nano-ZSM-5 molecular sieve into toluene, adding an organosilane containing a lipophilic group and reacting at 60-100° C. for 4-16 h, followed by centrifugation, washing and drying, to obtain a molecular sieve containing a lipophilic group;
• wherein the amount of substance of the toluene is 60-100 times that of the nano-ZSM-5 molecular sieve, and the amount of substance of the organosilane containing a lipophilic group is 6-10 times that of the nano-ZSM-5 molecular sieve;
• c) placing the molecular sieve containing a lipophilic group in a mixed solution of sodium hydroxide solution and ethanol and reacting at 60-95° C. for 20-60 min, followed by centrifugation, washing and drying, to obtain a molecular sieve containing a lipophilic group on the outside;
• and
• d) dispersing the molecular sieve containing a lipophilic group on the outside into toluene, adding an organosilane containing a hydrophilic group and reacting at 60-100° C. for 4-16 h, followed by centrifugation, washing and drying, to obtain the amphiphilic molecular sieve containing a lipophilic group on the outside and a hydrophilic group on the inside;
• wherein the amount of substance of the toluene is 60-100 times that of the molecular sieve containing a lipophilic group on the outside, and the amount of substance of the organosilane containing a hydrophilic group is 6-10 times that of the molecular sieve containing a lipophilic group on the outside.
