Chiral quaternary ammonium salts were synthesized from cinchonine in cinchona alkaloids using chloromethylated polystyrene - polyethylene glycol, diethylene glycol, triethylene glycol and glycol as polymer - supported phase transfer catalysts, finsl products were characterized by ftir, elemental analysis, scanning electron microscopy, x - ray photoelectron spectroscopy ( xps )
摘要以金雞納生物堿中的辛可寧為原料，氯甲基化聚苯乙烯聚乙二醇、一縮二乙二醇、二縮三乙二醇、乙二醇等為載體合成了幾種聚合物負載的手性季銨鹽，並對它們的結構用紅外光譜、元素分析、掃描電鏡和x射線光電子能譜等測試手段進行了表徵。( 2 ) an aminobenthiazole schiff base has been synthesized as a new fluorescence carrier by reacting 2 - aminobenthiazole with p - allyoxybenzoldohyde. the new kind of schiff base can be utilized for preparing an optical sensor, used for determining furazolidone based on the fluorescence quenching. aminobenthiazole schiff base immobilized on a glass plate surface by covalent bonding can circumvent the leakage of the fluorephore from the sensor surface and guarantee a relatively long working lifetime
（ 3 ）用強熒光基團2 -氨基苯並蒽酮與對烯丙氧基苯甲醛合成了另一種新的schiff堿類化合物，與甲基丙烯酸羥乙酯、丙烯酰胺、環乙二醇二丙烯酸酯共聚制得光極膜，制備了一種苯並蒽酮schiff堿光化學傳感器，可用於單質碘的測定。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。Polymerization and characterization of schiff base type liquid crystal polymers containing crown ethers schiff base type liquid crystal polymers containing crown ethers with high moderate weights were polymerized via low temperature solution polymerization
以二氨基二苯並冠醚和二醛類化合物為單體，通過低溫溶液聚合法合成了中等分子量的schiff堿型液晶高分子。Objectives : in our previous study, to improve the expression efficiency of human basic fibroblast growth factor ( hbfgf ) expressed in escherichia coli, we lowered the g + c content in hbfgf ' s tir region and used more preferred codons by e. coli. meanwhile we found the low insoluble product with a large quantity of dimer and higher multimer in the protein solution. it greatly decrease the bioactivity of hbfgf
目的：我們在長期實踐中發現，大腸桿菌中表達的人堿性成纖維細胞生長因子（ humanbasicfibroblastgrowthfactor ， hbfgf ）在e . coli中表達量不高，可溶性低，蛋白溶液中大量存在二聚體，三聚體以至多聚體，使得hbfgf的生物活性大大降低。分享友人
