摘要綜述了磺酸、無機鹽、固體超強酸、雜多酸、酶催化體系等對合成丁酸丁酯的催化作用及研究進展。Abstract : the mixed salts of diethanolamine and sodium of lauramidoethylene sulfosuccinate is prepared to modify the products with the mixture of the diethanolamine and hydrogen sulfite of sodium as sulphonating agent. the transparency problem of the product is solved. the result of investigation illustrates the major physocochemical properities of the products after the modifying are basically corresponding to the one before the modifying, and the products have a strong containing salt ability, it is fit to compound the products of the high salt content
文摘:採用亞硫酸氫鈉與二乙醇胺的混合物作磺化劑,對琥珀酸月桂酰胺基乙酯磺酸鈉進行改性,制得了鈉與二乙醇胺的混合鹽,改善了產品的透明度.性能分析表明:改性前後其主要表面物理性能基本相當,且改性后該產品具有較強的抗鹽能力,適用於含鹽量較高的製品The membrane properties were found to be dependent upon the content of styrene. the membrane physic - chemical properties compare to nafion 117 except that their chemical stability has to be further improved to make them acceptable for practical use in the proton exchange membrane fuel cell. the proton transport through the membrane follows the " liquid - like " proton conductivity mechanism y and the water balance is important for the working condition of the fuel cell
對磺化膜的研究分析表明:膜的性能參數如離子交換容量、吸水率、水合系數、形體穩定性、導電性能、化學與熱穩定性等依賴于膜中苯乙烯含量,且接枝苯乙烯相互間的位阻效應對膜性能影響很大;膜的性能可與nafion膜相比較;質子在膜中的傳導遵循「似液體」質子傳導機理;電滲析與擴散作用使膜保持水平衡。For example, the sulfonated and sulfomethlated materials and their derivatives have satisfactorily undergone tests as drilling mud thinners, and the results are comparable to those obtained with commercial mud thinners
比如,將磺化物質、磺甲基化物質及其衍生物作為鉆井泥漿稀料進行測試,效果令人滿意,其應用效果可以同商業泥漿稀料相媲美。For example, the suffocated and sulfomethlated materials and their derivatives have satisfactorily undergone tests as drilling mud thinners, and the results are comparable to those obtained with commercial mud thinners
比如,將磺化物質、磺甲基化物質及其衍生物作為鉆井泥漿稀料進行測試,效果令人滿意,其應用效果可以同商業泥漿稀料相媲美。The grafted membranes were capable of rejecting an anionic dyestuff. in common with other polyelectrolytes, the conformation of grafted ampsa polymeric chains is sensitive to environmental factors such as ph and ionic strength ( i )
聚丙烯酰胺基甲基丙磺酸為高分子電解質,接枝在膜表面后高分子鏈與溶質分子相互作用,可使接枝鏈構象發生變化,從而改變膜孔徑的大小,使膜具有環境響應。It is known that astrocytes take a key role in the response to hypoosmotic stimulation : astrocytes can perceive the change of osmotic pressure and release taurine which then activates glycine receptors on the neurons, and inhibits the release of vp from the neurons in son
現已發現星形膠質細胞在對低滲刺激的反應中起關鍵性的作用:星形膠質細胞感受滲透壓的變化,通過大量釋放牛磺酸( taurine ) ,作用於神經元上的甘氨酸( glycine )受體,從而抑制神經元釋放血管加壓素( vasopressin , vp ) 。This article aims at summarizing the development of research on synthesis of tributyl citrate and the catalysis of sulfonic acid, inorganic salt, solid superacid, heteropoly acid, rare earth compound
