  • In this study, to obtain isoindoline compounds with the high thermal resistance and reddish yellow color using an environmental friendly method without the use of any surfactants, isoindoline derivatives with different structures were added at various reaction temperatures for the synthesis and the product was then crystallized by controlling temperatures and times in autoclave. Chemical structures, particle sizes, color differences, and optical properties were evaluated by the means of FT-IR, FE-SEM, UV-Vis spectroscopy, PSA (particle size analyzer) and Zeta potential analyzer. The samples with an enhanced dispersibility, highly thermal resistance, uniform particle sizes were achieved possibly due to the addition of isoindoline derivatives into the crystallization processing mixtures. The color change trend was also observed depending upon synthesis conditions.
