As a common heterocyclic compound, it belongs to benzoxazole compound, name is 2-Benzoxazolinone, and cas is 59-49-4, its synthesis route is as follows.
In a reactor equipped with exhaust gas absorption, 27.0 g of benzoxazolone (molecular weight 135.1, 0.20 mol) was added, 245.3 g of phosphorus oxychloride (molecular weight 153.3, 1.6 mol), After stirring at room temperature for 30 minutes, Cool down to around 0 C, The chlorine gas is reacted, and the chlorine gas flow rate is about 20.0g per hour. The access time is about 3h (molecular weight 71, 0.21mol), The benzoxazolone content is detected during the chlorine process, When the benzoxazolone content is less than 1%, it is considered to be the end of chlorine.
59-49-4, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,59-49-4 ,2-Benzoxazolinone, other downstream synthetic routes, hurry up and to see
