study is made of the synergistic effect of inhibitor of two compositions on the HSAB principle. Experiment results show that the synergistic effect of some complex inhibitors is due to the fairly satisfactory matched relation between the organic inhibitors and the protected metals from the HSAB point of view. To repeat, the better the matched relation, the higher the inhibiting efficiency of the inhibitor. This is what we call "hard-soft matched synergistic effect" whic... 本文應(yīng)用軟硬酸堿原則研究了雙組份有機(jī)緩蝕劑的協(xié)同效應(yīng).實驗表明:某些復(fù)合緩蝕劑的協(xié)同效應(yīng),從軟硬酸堿原則看是由于有機(jī)緩蝕劑與被保護(hù)金屬之間有較好的酸堿軟硬度的匹配關(guān)系.復(fù)合緩蝕劑的軟硬度與被保護(hù)金屬的軟硬度匹配好的則有較好的協(xié)同效應(yīng);反之,則無協(xié)同效應(yīng).這種“軟硬匹配的協(xié)同效應(yīng)”,目前還未見文獻(xiàn)報導(dǎo)過. The mechanism of chelate and synergistic extraction of Pb++,Ni++,Mn++,Co++ Cd+++,Ca++, Mg++ and La+++ ions with l-phenyl-3-methyl-4-benzoyl-pyrazolone-5(HPZL)-benzene and HPZL-TBP-benzene solution were investigated by the two-phase titration method. The composition of the extracted chelates and synergistic complexes and their stability constants have been determined. The experimental results showed that for the metal ions which are extracted strongly the synergistic effects are weake... 本文報導(dǎo)用兩相滴定法研究HPZL和TBP的苯溶液對Pb~(++)、Ni~(++)、Mn~(++)、Co~(++)、Ca~(++)、Mg~(++)、Cd~(++)、La~(+++)諸離子的萃取和協(xié)同萃取機(jī)理得到的結(jié)果。 1.確定了有關(guān)萃合物和協(xié)萃絡(luò)合物的組成和相應(yīng)的平衡常數(shù)。 2.實驗表明,萃取作用比較強(qiáng)的金屬離子,協(xié)萃效應(yīng)比較弱;而萃取作用比較弱的金屬離子協(xié)萃作用則較強(qiáng)。所以,萃取性能比協(xié)萃性能更反映出金屬離子之間的差異。 3.發(fā)現(xiàn)配位數(shù)和配位鍵的共價性之間有以下關(guān)系:若配位鍵的共價性較強(qiáng),則配位數(shù)傾向于取較小的值,協(xié)同效應(yīng)較弱;若配位鍵的離子性較強(qiáng),則配位數(shù)傾向于取較大的值,協(xié)萃效應(yīng)較強(qiáng)。 The effect of UV stabilizers on plastics is introduced. Emphasis is laid on the discussion about the machanisms of hindered amine light stabilizer and benzotriazole UV absorber and the synergistic effect of combination of them as well. A comparison of the weather stability of polystyrene and ABS with/without UV stabilizer, and with hindered amine and benzotriazole combined also has been made. In the polystyrene composition, the Synergistic effect of the two stabilizers improves... 介紹了光穩(wěn)定劑在塑料中的作用,著重討論了受阻胺光穩(wěn)定劑與苯并三唑UV吸收劑的作用機(jī)理及其并用時的協(xié)同效應(yīng)。以聚苯乙烯和ABS為例,比較了不使用光穩(wěn)定劑、單獨(dú)使用一種光穩(wěn)定劑以及受阻胺與苯并三唑并用時的耐候性變化。結(jié)果表明,對聚苯乙烯,并用使光穩(wěn)定效果提高30多倍;對ABS,并用使抗沖強(qiáng)度保留時間延長20倍。此外,還介紹了其他類型光穩(wěn)定劑的一些較有意義的發(fā)展動向。 符合以上情景的話用synergistic effect,翻譯很多的,不知具體用法,不太好確定是哪一個! |
