查询词典 react

Methylglyoxal is a toxic endogenous substance known to react with proteins to form advanced glycation endproducts, which accumulated in the body during aging. Hyperglycemic can accelerate the accumulation of AGEs, and it has been link to the development of diabetic complications.

由於Methylglyoxal在体内会形成高阶糖化终产物，而这些终产物在老化过程中会大量蓄积且高血糖会加速其蓄积，而与糖尿病晚期的并发症有相当的关联性。

Methylol groups react with the hydroxyl groups of the cellulose to form stable ether linkage.

The first step reaction of methanol hydrochlorinate is methanol react with hedrogen chloride to produce monochloro methane and water, if the methanol can meet the request, the high pure monochloro methane can be refined.

甲醇法第一步反应为甲醇与氯化氢反应生成氯甲烷和水，如果所用原料甲醇满足要求，反应产物经过简单的精制即可得到高纯度的一氯甲烷。

Four different ionic liquids, BF4, BF and PF6 were investigated, arid PF6 showed the best effect when used as the reaction media, giving the highest yield in the shortest reaction time. Promoted by KF in PF6, N-aryl or N-alkyl monosubstituted sulfonamides could react with various activated halides and unactivated primary halides smoothly. Reactions were performed at 85℃ for 2~10 hours, and thirteen N-alkylation products were obtained with 70%~97% yields. Moreover, the ionic liquid recovered could be reused for three times with no appreciable decrease in yield and reaction rate.

结果表明，以PF6为反应介质时显示出了最好的效果，反应的时间最短，收率最高。N-芳基或N-烷基单取代的磺酰胺和各类不同结构的活化的卤代烃和未活化的一级卤代烃在PF6中KF作用下，85℃反应2~10h，以70%~97%的优良收率得到了13个N-烷基化产物，而且离子液体回收使用3次后效果未降低。
