Chemical engineers ensure the efficiency and safety of chemical processes, adapt the chemical make-up of products to meet environmental or economic needs, and apply new technologies to improve existing processes. 10541-83-0, Name is 4-(Methylamino)benzoic acid, molecular formula is C8H9NO2, Category: isothiazole, belongs to isothiazole compound, is a common compound. In a patnet, author is Hutchings, MG, once mentioned the new application about 10541-83-0.
Pronounced solvatochromic shifts are observed in the visible spectra of two series of heteroarylazobenzene derivatives based on m-acetylamino- and m-methyl-N,N-diethylaniline, measured in various solvents. The heteroaryl azo component of these dyes can be viewed as a thiophene ring substituted by cyano, nitro, alkoxycarbonyl, or ring aza (to give thiazole and isothiazole derivatives). Free-Wilson analysis has shown that the influence of each of the substituents is constant across all molecules within the two series for a given solvent. However, the substituent increments vary between different solvents and correlate with the Kamlet-Taft dipolarity/polarisability parameter pi* of the solvents. There appears to be no intuitive explanation for the relative solvent variation of different substituents, but Onsager theory suggests sensitivity to the relative size and shape of the dyes. Visible absorption maxima are predicted for unknown heteroarylazo compounds related to those studied. (C) 2000 Elsevier Science Ltd. All rights reserved.
Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step. If you are hungry for even more, make sure to check my other article about 10541-83-0, Category: isothiazole.
