It displayed that gdh pathway might be predominant and gs / gogat cycle be secondary in ammonia assimilation by analysis of the activity ratios of gs / gdh and gs / gogat . results indicated that the amination capability was enhanced in the non - heading chinese cabbage leaves treated with chitosan . the enhanced amination capacity by gdh would in turn lead to the increase of the soluble protein content 進一步對酶活性的比值( gs / gdh和gs / gogat )進行分析表明，在殼聚糖處理后的前期， gogat可能與gdh -起執行氨同化作用：而在后期，氨同化作用主要是由gdh完成， gogat與gs組成的途徑起著輔助的作用。
Aminated and hydroxylated polysulfone membranes were prepared by amination and hydroxylation reaction , respectively . then bovine albumin ( bsa ) - fixed membranes were obtained by crossed - linking albumin into porous membrane with 1 , 1 ' - carbonyldiimidazole and bisoxirane reagents , respectively . a mathematical model for facilitated transport in asymmetric membranes with fixed site carriers was derived by assuming an instantaneous , microscopic concentraion fluctuation in the membrane 以氯甲基聚砜為基材，通過相轉化法制備出具有底部貫通孔的非對稱膜，通過胺化和羥基化反應，分別制得胺化聚砜膜和羥基化聚砜膜，再采用羰基二咪唑和雙環氧烷兩種活化試劑對其進行活化，將牛血清白蛋白固載在膜內，獲得固定白蛋白促進傳遞膜。
At 100 to 150 , both the toughness and the molecular weight decreased during the process of amination , but the transformation ratio of the amination reaction increased rapidly ; above 150 , both the toughness and the molecular weight increased and transformation ratio of the amination slightly increased , and reached completely amination 亞胺化過程中，當溫度從100升至150時，不同熱處理階段薄膜的韌性和分子量均下降，亞胺化反應轉化率上升較快； 150后，其韌性和分子量均升高，亞胺化反應轉化率上升趨于緩慢，最終達到完全亞胺化。
( 6 ) 4 , 6 - diamino - 5 - nitrobenzofuroxan is designed to synthesis from trichlorobenzene through nitration aminatiom azidation and thermal decomposition . this compound is a new explosive . but we only got the intermediates of the first and second steps ( nitration , amination ) because the limit of time ( 6 )從均三氯苯出發，設計經硝化、氨化、疊氮化和脫氮四步合成4 ， 6 -二氨基- 5 -硝基苯并氧化呋咱，這是未見文獻報道的新化合物，不過由于時間關系，我們只得到氨化這一步的中間產物即3 ， 5 -二氨基- 2 ， 4 -二硝基氯苯，這也是個未見文獻報道的新化合物。
Abstract : two important factors , the loss of the catalyst components and the change of the catalyst particle diameter , which lead to the decay of the catalyst for amination of fatty alcohols , were studied . the dimension analytic method is applied successfully to determine the relations among the components loss , the particle diame - ter and the times of the catalyst used in repeated experiments 文摘:對引起脂肪醇胺化用催化劑失活的重要因素? ?組分流失及粒徑變化進行了研究，運用因次分析方法將催化劑的重復使用次數、組分流失及粒徑等因素進行了關聯，并取得了成功。
Furbenicillin sodium , a known semi - synthetic ureide type of antibiotic firstly marketed in china , was synthesized from starting material 2 - furaldehyde via six steps including oximation reaction , beckmann rearrangement , isocyannuration , amination , condensation and salification etc 摘要以呋喃甲醛為起始原料，經厲化、貝克曼重排、異氰脲酸化、氨基化、縮合和成鹽6步反應，合成了酰脲類青霉素抗生素呋布西林鈉。
Using ethyl cyanoacetate , triethyl orthoformate and methylhydrazine as main raw materials , the herbicide pyrazosulfuron was prepared through the reactions of substitution , amination , cylclization , diazotization and chlorosulfonation 摘要以氰乙酸乙酯、原甲酸三乙酯和甲肼等為主要原料，通過取代、胺化、環化、重氮化和氯磺化等反應制得了除草劑吡嘧磺隆原料藥。
United kingdom manufacturer of organic intermediates . specialties include amination , bromination , cyanation , epichlorohydrin , friedel - crafts and thionyl chloride chemicals -生產醋酸乙酯和醋酸丁酯等有機溶劑，產品用于醫藥香料染料涂料油墨等。
Therefore , in order to obtain polyimide with good mechanical properties , the temperature of amination should not be chosen at 150 因此，為了得到具有較好機械性能的聚酰亞胺， 150左右是應當避開的最終酰亞胺化溫度。
