At present, sodium bentonite was used as main raw material, and cationic surfactants such as long carbon chain quaternary ammonium salt and alkylamine were used as modifying agents when synthesize organobentonites
目前,制備有機膨潤土所用的原料主要為鈉基膨潤土,所用的插層劑主要是陽離子表面活性劑,如長碳鏈季銨鹽、烷基胺等。Using v2 & 5 and alkylamines ( cs - cao alkyl chain ) as precursor, vanadium oxide nanotubes which have an unique structure that alkylamines intercalate into layers of tubes wall affecting the layer spacing were prepared. their layers spacing ranges from 1. 25 nm to 3. 82 nm according to the length of alkyl chain. moreover, the growth mechanism of vanadium oxide nanotubes have been investigated and 3 - 2 - id model was established to interpret the vanadium oxide nanotubes growth process. potassium niobate is a functional materials which can be used as photochemical catalysts. lt is well known that the catalytic activites are affected greatly by the surface area of catalyst particles on which the reaction take place
以系列烷基胺和五氧化二釩為原材料,通過簡單的水熱反應合成出了氧化釩納米管,這種納米管結構獨特,烷基胺作為模板劑內嵌入納米管管壁層間,成為支持納米管的骨架,並影響層間距大小,納米管管壁層間距隨著烷基胺碳鏈長度的不同在很大范圍內變化,通過採用不同碳鏈長度的烷基胺( c _ nh _ ( 2n + 1 ) nh _ 23 n 20 )作為模板,來控制氧化釩納米管的層間距,層間距可調控范圍從1 . 25nm到3 . 82nm 。Natural phenalkamine curing agent for epoxy resins
天然長鏈取代酚醋胺固化劑In this thesis, organic - montmorillorite ( org - mmt ) was obtained - by an ion - exchange reaction between na + - montmorillorite ( na + - mmt ) and alkyl ammonium bromide, leading to increase the basal spacing of montmorillonite. xrd analysis indicated that alkylammonium ions had already exchanged with na + ions in na - montmorillonite and long alkyl - chains had entered into the gallery of montmorillorite
X -射線衍射( xrd )分析結果表明有機胺陽離子已同蒙脫土中的鈉陽離子發生離子交換作用,烷基長鏈進入蒙脫土層間,導致層間距擴大,並使蒙脫土層間親水性轉變成親油性。Methods of testing water used in industry - long - chain fatty amines : spectrophotometric method
工業用水試驗方法.第117部分:長鏈脂肪胺:分光光度法A newly made amino acid chain folds into a distinctive shape depending on the positioning of hydrophobic amino acids, which like to cluster together away from the cell ' s watery cytoplasm, leaving hydrophiles to form the protein ' s surface
剛合成好的胺基酸長鏈,會根據疏水性胺基酸的分佈位置,摺疊成蛋白質的獨特形狀:疏水性胺基酸彼此向內聚攏,避免接觸到富含水的細胞質環境;親水性胺基酸則向外翻出,構成蛋白質的表面。Mainly used in engineering plastics, ploy - carboned nylon and its products
