New discoveries in chemical research and development in 2021. The transformation of simple hydrocarbons into more complex and valuable products has revolutionised modern synthetic chemistry. In an article, author is Han, So Hee, once mentioned the application of 307-24-4, Reference of 307-24-4, Name is Undecafluorohexanoic acid, molecular formula is C6HF11O2, molecular weight is 314.0534, category is benzoxazole. Now introduce a scientific discovery about this category.
A series of poly(hyroxyamide)s (PHAs) was prepared by direct polycondensation reaction of 4,4′-(2,3-pyridinedioxy)dibenzoic acid and/or isophthalic acid with 3,3′-dihydroxybenzidine. The yield percentages of the products were high, and the inherent viscosities of the polymer in DMAc solution at 35 degrees C were 0.31-0.59 dL/g. All PHA polymers were found to be soluble in polar aprotic solvents such as DMAc, DMSO, NMP, and DMF. On the other hand, LiCl was required to dissolve IPHA-1 in aprotic solvents. Poly(benzoxazole)s (PBOs) were partially soluble in conc-H2SO4; IPBO-4, -5, and -6 were partially soluble in NMP only when LiCl was added to the solution, and the solution was heated. The PBO polymers showed a maximum weight loss in the temperature range of 654-680 degrees C, and the char yields at 900 degrees C under nitrogen atmosphere exceeded 63%.
Reference of 307-24-4, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 307-24-4 is helpful to your research.
