Let's … WebSep 1, 1998 · The presence of these peaks suggests the formation of some oxidative decomposition products of polyaniline and/or by-products from oxidized aniline which has not been polymerized. The appearance of a peak near 1650 cm −1 on a longer exposure time indicates that the formation and decomposition of polyaniline compete with each …
WebBenzene is prepared from ethyne by the process of cyclic polymerization. In this process, Ethyne is passed through a red-hot iron tube at 873 K. The ethyne molecule then undergoes cyclic polymerization to form benzene. Preparation of benzene from aromatic acids Benzene can be prepared from aromatic acids through decarboxylation reaction. WebAniline structural formula is shown below-. Structure of aniline- If you take out one hydrogen from ammonia and attach a benzene group with it, it gives us the structure of aniline. Aniline molecular formula is C 6 H 7 N and chemical formula is C 6 H 5 -NH 2. The molecular weight of aniline is 93 g/mol (12×6 Carbons+7×1Hydrogens+14×1Nitrogen)
