WebbA procedure was developed for the simultaneous determination of phthalic acid isomers; the procedure includes the preparation of diisoamyl esters by reaction with isoamyl alcohol in a benzene solution in the presence of sulfuric acid with the distillation of an azeotrope mixture of benzene with water, the neutralization of acid with triethylamine, and the … WebbThe exothermic nitration of phthalic acid or phthalic anhydride by fuming nitric acid-sulfuric acid may give mixtures of the potentially explosive phthaloyl nitrates or nitrites …
WebbWhat is Phthalimide? Phthalimide is acidic, since its conjugate base is resonance stabilised. Bromine is an electrophile, since it is electronegative and bromide is a good leaving group. Sodium hydroxide is a good base. The Phthalimide group is the most acidic site and hydroxide is the strongest base. Bromine is the only electrophile. Webb28 apr. 2003 · The nitration of 1-methylindole-3-aldehyde, 2-methylindole-3-aldehyde and 1,2-dimethylindole-3-aldehyde in sulphuric acid gives in ca. 92% yield mixtures of the corresponding 5- and 6-nitro ...
Webb2. Secondly, you will titrate a weak acid, Potassium Hydrogen Phthalate (abbreviated KHP), with a strong base. Phthalic acid is a weak, diprotic acid. On the other hand, KHP is the potassium salt of phthalic acid. Hence, KHP is a weak monoprotic acid. From the results of this titration you will be able to calculate the K a for KHP. The equation ...
