Product Name:2-Allyloxy-1,3,5-tribromobenzene
CAS Number:3278-89-5
Molecular formula:C9H7Br3O
Molecular Weight:370.86

To the ethanol solution of the sodium tribromophenolate salt prepared in the step 1), the dispersing agent sodium stearate 2.5 g is added.And catalyst II phenyl triethyl ammonium chloride 5.6g,The temperature is raised to 75 ° C to reflux the reaction.Further, 1000 ml of an ethanol solution of chloropropene having a volume ratio of chloropropene to ethanol of 1:5 was slowly added thereto, and then the reaction was kept at 75 ° C for 6.5 h until the end.Then, the temperature is lowered to 7 ° C in sequence, and then suction filtration is performed to recover the ethanol solution.After washing the filter cake with water, the filter cake was dried at 60 ° C.2,4,6-Tribromophenyl allyl ether was obtained as a white powdery solid in a yield of 96.2%.
