[0034] The synthesis of embodiment 1TS-1 molecular sieve
[0035] 1. Take 15 grams of ethyl orthosilicate (according to SiO 2 0.07mol) was added to 17 grams of tetrapropylammonium hydroxide (concentration is 25%, 0.02mol by TPAOH), stirred for 30 minutes to obtain the silicon source hydrolyzate, and 1.62 grams of butyl titanate (by TiO 2 0.00466mol) was added to 9.28 grams of isopropanol (0.155mol), stirred for 5 minutes, added to the above-mentioned silicon source hydrolyzate, stirred for 60 minutes, added 39.3 grams of water (2.18mol), stirred for 30 minutes, and the initial gel;
[0036] 2. Put the initial gel into the reactor and crystallize at 100 degrees Celsius for 7 hours, and cool to room temperature after crystallization;
[0037] 3. Take 15 grams of ethyl orthosilicate (according to SiO 2 0.07mol) was added to the product obtained in step 2, stirred for 30 minutes, heated and stirred in a water bath at 60 degrees Celsius for 150 minutes to remove isopropanol to o...
