59-49-4, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 2-Benzoxazolinone, cas is 59-49-4,the benzoxazole compound, it is a common compound, a new synthetic route is introduced below.
135.1 kg of 99.3% pure 2-benzoxazolone (VI) obtained by the procedure of Example 1 was mixed with 533.3 kg of liquid base (15%), stirred, and heated to 95-105 C,The pressure is from 0 to 0.15 MPa until the reaction is complete, and the hydrochloric acid is acidified to a pH of 7,Solid-liquid separation, 100.7 kg of o-aminophenol (VII) with a purity of 99.0%,The yield was 96.5%; the residual in the filtrate was extracted by extraction with dichloroethane.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 2-Benzoxazolinone, 59-49-4
