Description
Summary:<p>This work aimed to evaluate the influence of Cu<sup>2+</sup> salts counterions (acetate and chloride) and the synthesis conditions on the reaction yield of MOF-199, a well-known metalorganic framework. Therefore, a factorial design was performed for this purpose in which three reaction parameters were analyzed: temperature, time and metal concentration, varying in two levels (minimum and maximum), resulting in a combinatorial analysis, where each experiment consisted in a different configuration of the factors at their respective levels, which led to a batch of 23 = 8 experiments, for each Cu<sup>2+</sup> salt. Syntheses with average values of each parameter were also performed, totalizing 9 experiments for each counterion. Reaction yield was the factorial design response variable and the products were characterized by infrared vibrational spectroscopy, thermogravimetric analysis and powder X-ray diffraction. Analytical techniques confirmed the production of MOF-199 and the proposed statistic model of the response variable showed good agreement with the experimental values. In addition, the temperature parameter was the only significant variable on the reaction yields for the syntheses with Cu<sup>2+</sup> chloride. The syntheses carried out with Cu<sup>2+</sup> acetate provided higher yields compared to Cu<sup>2+</sup> chloride, however the evaluated synthesis conditions were not significant.</p><p> </p><p>DOI: <a href="http://dx.doi.org/10.17807/orbital.v10i7.1213">http://dx.doi.org/10.17807/orbital.v10i7.1213</a></p> <p><strong> </strong></p><p> </p>
