“…Schiff bases have found wide applications in the field of coordination chemistry (Sallam, 2006), biological processes (Snatos et al, 2005), several enzymes (Clarkson and Basolo, 1973), microcalorimetry (Li-Xia et al, 2006), cytotoxic (Tarafder et al, 2002), insulin mimetic agents (McNeill et al, 1992), anticonvulsant (Panchagnula et al, 2004), antiproliterative (Vicini et al, 2003), antifungal activities (Pignatello et al, 1974), transport of oxygen in mammalian and other respiratory systems (Singh et al, 2010). Few Schiff's bases are prepared, characterized and determined the kinetic parameters of chitosan with salicylaldehyde (Guinesi and Cavalheiro, 2006), trans 1,2-cyclohexadiamine with salicylaldehyde (Aranha et al, 2007) and 4-aminoantipyridine with 2-aminophenol (Mohamed et al, 2009). Literature data show that no work has been reported on thermal decomposition of anil at different heating rates (10, 15 and 20 K min À1 ) under non-isothermal condition in nitrogen atmosphere.…”

“…O grau de acetilação de quitosana e quitina podem ser determinados pelas técnicas baseadas em titulação condutimétrica (RAYMOND et al, 1993;SANTOS, 2004), em espectroscopia no infravermelho, (BRUGNEROTTO et al, 2001), espectroscopia de ressonância magnética de 1 H ou de 13 C, (HIRAI et al, 1991;RAYMOND et al, 1993), espectroscopia no ultravioleta (TOLAIMATE et al, 2000), em análise elementar (NIOLA, 1993), cromatografia líquida de alta eficiência (ROBERTS, 1992), potenciometria (KE; CHEN, 1990), dicroísmo circular, cromatografia de permeação em gel, e técnicas termogravimétricas, tais como TG (ALONSO et al, 1983;NIETO et al, 1991), DSC (GUINESI; CAVALHEIRO, 2006a;KITTUR et al, 2002;NIETO et al, 1991;RATO;HATAKEYAMA, 1995) e DTA também podem ser usadas (TOLAIMATE et al, 2000;HORN, 2008).…”

“…O grau de substituição nada mais é que o número médio de grupos que podem ser inseridos no interior de uma estrutura por unidade biopolimérica e essa substituição pode se dar de forma parcial, completa ou simplesmente pode não acontecer (ENCYCLOPEDIA, 2011;CAVALHEIRO, 2006a;). O rendimento das reações destas iminas é dependente do substituinte e calculado a partir da análise elementar de géis secos.…”
