UNIFAC模型在草酸二乙酯合成体系中的应用 总被引:1,自引:1,他引:0
利用原始UNIFAC模型对CO气相催化偶联合成草酸二乙酸产物中的各组分进行了基团划分,用实验测定的二元物系等温汽液平衡数据,关联了CH2O/HCOO基团相互作用参数,汽液平衡计算值性实验值比较偏差较大。为提高推算精度,对碳酸二忆是进行新的基团划分,提出了UNIFAC新基团OCOO,重新关联基团相互作用参数并进行了汽平稳推算,结果令人满意。 相似文献

A series of synthetic methods for synthesis of organic compounds containing naphthyloyl group have been explored via one-pot reactions catalyzed by zinc oxide nanowires (ZnO NWs). In the first reaction, new biscoumarins have been synthesized through the reaction of naphthyl glyoxals with 4-hydroxycoumarin. In the next one, new pyranocoumarins have been obtained from the one-pot, three component reaction of naphthyl glyoxals with malononitrile and 4-hydroxycoumarin. In the final study, the naphthyl glyoxals were also employed for the synthesis of new amidocoumarins in a three-component reaction with 4-hydroxycoumarin and benzamide. It is noteworthy to mention that the green chemistry principles have been considered in all strategies. The advantages of the present methods are good product yield in a short reaction time, avoidance of toxic and expensive organic solvents, use of safe and recoverable catalyst, and simple operation. 相似文献

Poly(vinyl alcohol) (PV-OH), prepared from poly(viny) acetate), is used widely in many industries. Various grades have been produced, with different degree of polymerization and degree of hydrolysis. Recently, novel modified (PV-OH)s with anion, cation, silanol or hydrophobic groups have been studied and developed. They have new properties in addition to those of ordinary PV-OH and have new applications. The methods of modification and the characteristics and some applications of the modified polymers are described. 相似文献
