    二甲基甲酰胺二異丙基縮醛對羧酸酯化反應的研究
  5. There were limited reports about the metabolism catalyzed by ugt1a9. ugt1a9 mainly catalyze the glucuronidation of hydroxyl to produce o - glucuronide. besides, ugt1a9 also catalyze the glucuronidation of carboxyl and hydroxylamine compounds

    有關ugt1a9的代謝作用研究不多，從文獻報道來看， ugt1a9主要催化羥基上的綴合反應，形成o -葡醛酸苷，此外它也能與羧基、羥肟酸形成葡醛酸苷。
  6. Gas chromatography - mass spectrometry ( gc - ms ) analyses showed that both potassium permanganate and chlorine could oxidate the organic matters with unsaturated functional groups into those with carboxyl, hydroxyl and aldehyde. and it was further revealed that after preoxidation by potassium permanganate, the sorts of organic matters were reduced remarkably, however, chlorination leaded to increase of the sorts of orgnic matters and brought some chloro - organics such as chlorobenzene, chlorophenol, and trichloro - ethane

    通過色譜-質譜聯用（ gc - ms ）評價分析了高錳酸鉀和氯對有機物結構的改變，高錳酸鉀和氯均將原水中的一些不飽和性有機物氧化分解為一些含氧基團的有機物，如羧酸類、醇類和醛等有機物，但預氯化會在水中出現一些鹵代物，鹵代產物不僅出現在苯環上，而且出現在鏈烴上。
  7. ( 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。
