hydroxyl bond 中文意思是什麼

hydroxyl bond 解釋
羥基間鍵
  • hydroxyl : n. 【化學】羥基。
  • bond : n 1 結合(物),結合力,黏合(劑),聯結。2 束縛,羈絆; 〈pl 〉 拘束;鐐,銬。3 契約,契約義務,...
  1. In all those complexes, no matter which conformation ida assumes ( mer - or fac - style ), the two 0 atoms of 1n2o are both from carboxylic hydroxyl. however, by comparing the bond length, we can find that o ( 4 ) and o ( 2 ) atom is from different group in this complex, 0 ( 4 ) atom from carboxylic hydroxyl, whereas, 0 ( 2 ) from carboxylic carboxide

    值得注意的是:在這個雙核配合物中,我們首次發現一種新穎的配位方式: ida上與金屬離子配位的三齒螯合原子是亞氨n原子、一個羧基上的羥基o原子和另外一個羧基上的羰基o原子。
  2. For example, poly ( xylylviologendibromide ) and 4, 5 - bis ( 4 - methoxyphenyl ) - 2 - ( 4 - nitro - pheny ) imidazolium acetate di - hydrate ( c23h20n3o4 + c2h3o2 - 2h2o ), the hydration or dehydration of the crystal structure is related to the color charge of the crystal. the thermochromic schiff bases are the other family of compounds that show a self - isomerization induced by an intramolecular proton transfer from the hydroxyl oxygen to the imine nitrogen through the o - h. . n hydrogen bond, and they were observed thermochromism

    利用液相法合成了兩種具有熱色性新的有機水合物, x射線單晶衍射確定了這兩種水合物的結構,利用uv 、 ir 、原位升溫紅外、原位升溫紫外、 tg - dsc探討了它們的變色機理。
  3. ( 3 ) volume shrinkage of composite decreases greatly with wpu increasing, even can arrive a negative number, but thermal stability is still good. ( 4 ) toughening mechanism is that : the formation of high molecular linear amino formate construct is the toughening reason ; hydroxyl - terminated pu - prepolymer and pf react to produce chemical bond effect which participate cure ; carboxyl - terminated pu - prepolymer and pf form semi - ipn which make toughened pf occur maximum

    ( 4 )通過紅外光譜對pf / pu共混物分子結構進行的定性分析、以及掃描電鏡對沖擊斷面形貌進行的分析,可證明聚氨酯預聚物增韌酚醛樹脂的機理是:兩個體系都是由於高分子量的線形氨基甲酸酯結構而增韌;端羥基pu與pf在共固化中產生化學鍵效應,參與pf的固化;而端羧基pu則與pf形成半互穿網路而增韌。
  4. Ft - ir spectrum show that water insert between the inner layer of kaolinite with potassium acetate, which form hydrogen bond with the inner surface hydroxyl of kaolinite

    傅立葉變換紅外光譜顯示,水和乙酸鉀一同插入到高嶺土的層間,並與高嶺土的內表面羥基形成了氫鍵。
  5. And the molecule has amido bond and adsorb hydroxyl of polyphenol molecule to form hydrogen bond, therefore it can uses as stabilizer of beer, ratafee and potable spirit, prolong the quality guarantee duration to 300 days, and also can improve the transparence, color and taste

    應用最廣的是片劑顆粒劑的粘合劑。 pvp還可用作膠囊的助流劑,眼藥的去毒劑及潤滑劑,注射劑的助溶劑,液體制劑的分散劑,酶及熱敏藥物的穩定劑。
  6. Several mechanistic studies indicated that the structural features necessary for the expression of mutagenic activity include a hydroxyl group at position c13 and an unsaturated bond joining the c16 and c17 carbon atoms of steviol

    多項生理機能研究顯示,顯露基因突變的特性結構位於甜菊醇c13位置的羥基組,以及連結c16和c17碳原子的不飽和鏈。
