Ethyl cellulose was synthesized successfully in one - step based on reaction of cellulose with excess chloroethane and sodium hydroxide in toluene as diluent
摘要採用纖維素與過量的氯乙烷及氫氧化鈉反應，以甲苯為稀釋劑，用一步法成功地合成了乙基纖維素。 -
This method, however, involves using a large excess of diethyl carbonate ( for example, 4 - 8 mols. ) ; it also involves preparing sodium ethylate by dissolving sodium metal in ethanol, which process must be carried out very slowly and carefully if it is to be used on a manufacturing scale
但是這一方法涉及到使用大量過量的二乙基碳酸酯（例如， 4 - 8摩爾） ；同時也涉及到在乙醇中溶解納來制備乙醇納的反應，這個過程必須非常緩慢小心地進行，如果在工業生產級別上是用這一方法就比較麻煩了。 -
A series of near roundness cds nanoparticles with a particle diameter of 3 ~ 6nm have been prepared by controlling the concentration and proportion of reactants and adopting sodium hexametaphosphate as stabilizing agent. the studies demonstrate that these particles present obvious quantum size effect and an appropriate excess of cd2 + ion and hexametaphosphoric acid group polysnion are helpful to the dispersion and flame capability ' s improvement of particles. another series of near roundness monodisperse au nanoparticles with a diameter of 12. 3nm was prepared via sodium citric acid deoxidizing auric chloride acid
利用六偏磷酸鈉作為穩定劑，通過控制反應物的濃度及比例，制備了粒徑為3 6nm 、呈近似球形的cds納米顆粒，光譜測試結果表明，顆粒具有明顯的量子尺寸效應，適當過量的cd ~ （ 2 + ）離子以及六偏磷酸根聚陰離子有助於顆粒的分散並提高其發光性能；採用檸檬酸鈉還原氯金酸，制備了接近球形、平均粒徑約為12 . 3nm的單分散體系au納米顆粒；採用wessling的前驅聚合物法獲得導電聚合物ppv前驅體。
