On November 30, 1989, Porwisiak, Jacek; Dmowski, Wojciech published an article.Related Products of 41819-13-0 The title of the article was An improved synthesis of dihalopyromellitic acids. And the article contained the following:
Durene (I, R = H) is halogenated to give I (R = Cl, Br), followed by oxidation with HNO3 and a catalytic amount of NH4VO3 to obtain a mixture of polycarboxylic acids. Subsequent oxidation with KMnO4 gives the title compounds II (R = Cl, Br) in 50-52% yield. The experimental process involved the reaction of 3,6-Dibromobenzene-1,2,4,5-tetracarboxylic acid(cas: 41819-13-0).Related Products of 41819-13-0
