Synthesis of Bipolar Ion Exchange Resins Syntheses of weakly acid/strongly basic and weakly acid/weakly basic bipolar ion exchange resins with varying acid and basic capacities via subsequent introduction of the exchange active groups in suitable crosslinked skeletal polymers are described. Methylacrylate-styrene-divinylbenzene polymers of varying composition which can be quantitatively chloromethylated and subsequently fully aminated (trimethylamine) and partially saponified in one process step were used as starting polymers for weakly acid/strongly basic resins. The reverse route saponification of the ester groups first, followed by chloromethylation of the aromatic parts of the matrix and animation turned out to the possible, if at all, only for bipolar resins of strongly predominant basic character. The capacity parameters can be controlled through the composition of the matrix. Polymethylacrylates crosslinked with divinylbenzene served as polymer basis of the weakly acid/weakly basic bipolar ion exchange resins. The functionalization was achieved by partial aminolysis with polyamines (dimethylaminopropylamine, ethylenediamine, diethylenetriamine) and saponification with lyes. The number of basic and acid groups which can be introduced is governed primarily by the conditions of the aminolysis. The capacity parameters are controllable within a broad range by the procedures. 相似文献

氧化铝柱层析分离磷脂工艺的洗脱研究 总被引:1,自引:0,他引:1
开展了不同洗脱液组成对氧化铝柱上磷脂洗脱曲线影响的实验研究.分别用甲醇和甲醇-氨水体系做为洗脱剂进行洗脱,得到了最佳的洗脱液组成:甲醇:氨水=20:1(v/v).在此条件下,卵磷脂PC和脑磷脂PE的洗脱率分别达到了98.6%和32.3%.这为用氧化铝柱层析来同时制备卵磷脂和脑磷脂的工艺的工业化研究奠定了重要基础. 相似文献

The correlation between the ash composition of various incinerated waste residues and their melting temperatures was examined by using their chemical composition parameters. There was a low correlation between the melting temperatures and the acidic oxide content in the ashes. However, the composition parameters derived from the basic oxides showed a good correlation with the ash melting temperature. The composition parameter, P7, which is defined as the ratio of basic oxides (CaO+MgO+K2O+Na2O) to acidic oxides (SiO2+Al2O3+Fe2O3), showed a strong correlation with the ash melting temperature. By fitting the composition parameter to the experimental data, the correlation equation for the half fluid temperature (HFT) was found to be HFT=426.77P 7 2 ?736.76P7+1592.3 with a correlation coefficient of 0.91. The correlation equation could be used to predict the melting temperatures of various waste incineration residues. The relative error between the measured and predicted melting temperature was approximately 5%. Overall, these parameters and correlation equations can be used to predict and reduce the melting temperature of incineration residues. 相似文献
