Ultrasonic Study of Binary Liquid Mixtures of Triethyl Amine With Primary Alcohols at 303.15 K
Abstract: Most of the physical properties change whenever there is a change in the composition and structure of the liquid mixture. Then non-linear dependence of the physical–chemical properties with composition has been attributed to the size, shape, and polarity of the molecules. Ultrasonic velocity is one such property which is very important for the study of molecular interactions in solution. It gives information about the extent of interaction and some other …

Elucidation of Synthetic Mechanism Involved in the Conversion of Zwitterionic Clonixin to Carboxamide Side-Product
Abstract: N-(3-Chloro-2-methylphenyl)-2-oxo-1,2-dihydropyridine-3-carboxamide is obtained as a by-product during the synthesis and crystallization of Clonixin (2-(3-chloro-2-methylanilino)nicotinic acid) and its polymorphs, respectively. This conversion was unexpected and it changed the usual investigation path way enabling the formation of neutral and zwitterionic polymorphs in our study on Clonixin in contrary to studies of 2-(p-tolylamino) nicotinic acid investigation. The same conversion is checked in the other synthesized analogs such as 2-(phenylamino)nicotinic acid (PNA), 2-(methyl(phenyl)amino)nicotinic acid …
