Synthesis of new fireproofing agents for fibers. 1 was written by Sumi, Koichi. And the article was included in Osaka-furitsu Sen’i Gijutsu Kenkyusho Kenkyu Hokoku in 1978.Electric Literature of C8HBr4NO2 This article mentions the following:
2,4-Bis(tetrahalophthalimido)-6-chloro-s-triazines I, where R is Cl or Br, were prepared and were useful as fireproofing agents for textiles. For example, 1.78 mol formamide [75-12-7] was treated with 0.07 mol tetrachlorophthalic anhydride [117-08-8], 0.035 mol of the resulting tetrachlorophthalimide [1571-13-7] was treated with 0.035 mol KOH, and 0.0334 mol of the K salt [59653-19-9] was treated with 0.0167 mol. cyanuric chloride [108-77-0] to give I (R = Cl) [73341-50-1]. In the experiment, the researchers used many compounds, for example, 4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7Electric Literature of C8HBr4NO2).
4,5,6,7-Tetrabromoisoindoline-1,3-dione (cas: 24407-32-7) belongs to indole derivatives. Indole produced by Proteus, Pseudomonas, Escherichia and other species was shown to be a growth promoting factor in Arabidopsis thaliana. Indole plays a fundamental role for QS in E. coli, being one of the signal molecules responsible for the transcription of a variety of genes (gabT, and tnaB ASTD). Electric Literature of C8HBr4NO2
