英文
heptane insoluble matter-
Pentane insolubles by membrane filtration
薄膜過濾法測定戊烷不溶物Standard test method for pentane insolubles by membrane filtration
薄膜過濾法測定戊烷不溶物的標準試驗方法No probe leakage was found when the sensor dipped in ethanol and n - hexane for 15 days. this technique is limited for its prolix procession and request of special active function in the structure of molecular probe, sol - gel : the development of sol - gel technique provides a convenient way to incorporate molecular probe in porous inorganic material
化學鍵合法:分子探針通過化學反應鍵合於固定相,在溶劑中不泄漏,提高了傳感器使用壽命,在乙醇和正己烷中浸泡15天,未見探針分子泄漏。但繁雜的過程和對探針分子結構的特殊要求限制這一方光纖化學傳感器、儀器系統的研製們比生物和環境監測中的應用(摘要) 2法的應用。The mixed solvent consists of solvent naphtha, decalin, and petroleum ether in a certain proportion, which was used to synthesize 3 - sulfo p - anisidine by using p - anisidine as raw material
摘要用溶劑汽油、萘烷、石油醚按一定比例復配成混合型溶劑,以對茴香胺為原料,用該溶劑合成了3 -磺酸基對茴香胺,產品中不含致癌物。The electrode was found to decrease the solubility of dithizone in alkalescence solution and effectively minish the lose of deoxidize state of metal. third, a potentiometric sensor was prepared by adding copper diethyldithiocarbamate directly into the carbon paste mixture, and the electrode was found has nerst response to copper ion in solution. and in our research two pharmaceutical selective electrodes were fabricated by coating polyvinyl chloride ( pvc ) which contained electroactive material on carbon rod electrode
第二,利用- cd與環氧氯丙烷形成的交聯聚合物( - cdp ) (不溶性)包合了雙硫腙,然後將- cdp與雙硫腙包合物樹脂作為修飾劑制備了碳糊修飾電極,利用陽極溶出伏安法( asv )測定了pd ~ ( 2 + ) ,實驗發現通過包合降低了雙硫腙在堿性溶液中的溶解度並且減少了金屬還原態的流失,取得了較好的效果。The concentration of sulfur compound was the highest in steam distilled onion oil while it was lower in the extract of hexane and alcohol ( at 25 ) : there was no significance difference between solvent extracts
在含硫化合物濃度上,水蒸汽蒸餾得到的洋蔥精油明顯高於正己烷或乙醇萃取得到的油樹脂,而不同溶劑萃取得到的油樹脂含硫量相差不多。A novel aqueous two - phase system can be formed by the mixtures of a polymer and cationicanionic surfactants. such a system can be used as a partitioning system of proteins. in this work, we investigated the formation, phase behavior and protein partitioning in aqueous two - phase systems formed by dodecyltriethylammonium bromide / sodium dodecylsulfate / peg and dodecyltriethylammonium bromide / sodium dodecylsulfate / dextran. the ligands with affinity were attached to the polymers and the affinity partitioning of proteins was investigated. it was shown that the surfactants and polymers are enriched in different phases of aqueous two - phase systems. phase separation are promoted by increasing temperature and adding inorganic salts. different proteins are partitioned in different phases. the selectivity of protein partitioning is increased by adding ligands with affinity
報道了由正負離子表面活性劑與高聚物混合溶液形成的一種可用於蛋白質的分離及分析的新型雙水相萃取體系.研究了正負離子表面活性劑(溴化十二烷基三乙銨/十二烷基硫酸鈉)分別與葡聚糖和聚乙二醇混合雙水相體系的形成規律、相行為及牛血清蛋白和溶菌酶在雙水相體系中的分配.通過在高聚物分子中接上親和配基,研究蛋白質在雙水相體系中的親和分配.結果表明,在該體系中,表面活性劑與高聚物分別富集於不同相中.升高溫度及加入無機鹽均可促進雙水相體系的形成,不同蛋白質可分配于不同的相中.親和配基的引入極大地增強了蛋白質分配的選擇性分享友人
