Yield:-

Reaction Conditions:

at 210;Molecular sieve;Temperature;

Steps:

15 Example 10 Preparation of Product II
General procedure: Weigh 7.50 g of 13X molecular sieve (2 to 3 mm in diameter).Filled in a quartz reaction tube, the reaction tube inlet is connected to the constant pressure dropping funnel through a curved tube.The reaction tube outlet was connected to a condenser tube, a tail tube and a round bottom flask; 7.50 g of Example 9 was weighed.The obtained dehydrogenation material is added to a constant pressure funnel;Heat the quartz reaction tube to 230 ° C,Control the material drop acceleration to ensure the reaction mass airspeed is 3h-1 (all materials are added at a constant rate within 18min)The effluent product II was collected for gas phase analysis and the results were:Carvacrol 26.94%,3-isopropyl-5-cresol62.82%.
