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.
Step 3,Add 1.5 eq of TCCA to the suspension of dichloroethane containing the 2-benzoxazolone obtained in Step 1,Stir at room temperature for 10 min, after extraction,After rotary evaporation, 6-chlorobenzoxazolone was obtained.The yield is over 90%, no catalyst is needed, no by-products,The reaction rate is fast and there is no requirement for temperature.The method of step 3 is simple to operate,Low equipment requirements, no harm to the environment, suitable for large-scale production.
The chemical industry reduces the impact on the environment during synthesis,59-49-4,2-Benzoxazolinone,I believe this compound will play a more active role in future production and life.
