影響十二烷基多糖苷的合成因素研究 |
| 姜煒; 李鳳生(南京理工大學(xué)國家特種超細粉體工程技術(shù)研究中心; 江蘇南京) |
| 摘 要：采用交換法合成十二烷基葡萄糖苷,考察了催化劑、醇糖比、反應時(shí)間、反應溫度及脫醇工藝等對反應結果的影響。結果表明,優(yōu)惠工藝條件是:反應溫度為110℃左右催化劑/葡萄糖摩爾比為0 01∶1、正丁醇/葡萄糖摩爾比為5∶1、十二醇/葡萄糖摩爾比為6∶1的條件下反應,經(jīng)柱層析去除殘留正十二醇,十二烷基多糖甙收率為85 5%,并測定了產(chǎn)品的表面張力和起泡性能。 |

| Study on the Synthesis of Dodecyl Polyglucoside |
| JIANG Wei; LI Feng-sheng （National Special Superfine Powder Engineering Research Center; Nanjing University of Science & Technology; Nanjing 210094; China） |
| Abstract：Synthesis of dodecyl polyglucoside by means of exchange method was studied.Influence factors of reaction result,for example,catalyst,mole ratio of alcohol to glucose,reaction time,reaction temperature and refining process,etc,were investigated,and the optimal conditions of synthesis process had been obtained,i.e.,reaction temperature 110?℃,mole ratio of catalyst,butanol and doecand to glucose 0.01∶1,5∶1 and 6∶1,respectiviely.The refining process was carried out by the method of column chromatography,and the... |
