Yield:187737-37-7 99%

Reaction Conditions:

with tungsten(VI) oxide;silica gel in water at 350; under 16501.7 Torr;

Steps:

2

A metathesis catalyst was obtained by physically mixing 9 wt% WO₃ on a support containing 95 wt% of silica and 5 wt% of Y-zeolite with Mg~Al-CO₃ layered double hydroxide in the ratio of 10: 1 by weight. 2.2 g of white clay (binder) and 110 mL of demineralized water was added to 110 g of the metathesis catalyst and. the powder and water are immediately threshed to activate the binder and get homogeneous wet pre-extruded catalyst. Next, the wet catalyst is fed into an extruder. Then, the catalyst extrudate, getting from the extruder, is dried at 150°C for 3-4 hr in an oven. The obtained catalyst was subjected to a reaction test where ethene and 2-butene are reacted to form propene over the catalyst at 350°C and 22 bar gauge with 3 options of the upstream system zone as follow for comparison
