安息香的

The third part studied the influence of polar modifier and column temperature on enantioseparation of benzoin on Chiralcel OD-RH primarily.

第三章研究了极性有机溶剂及温度对安息香在Chiralcel OD-RH柱上拆分的影响。

Other fixatives which may be used include the oleoresins such as benzoin, or styrax

其他可用的固定剂有苯偶姻或安息香等含油树脂。

In addition, the effect of photoinitiators, barefoot initiationless will make the system turned yellow cured, such as benzoin double ether, so you should avoid the use of such light initiationless, on confecting

另外，光引发剂的影响也很大，有些光引发剂会使体系固化后发黄，如安息香双甲醚，所以应避免使用这类光引发剂配制上光油

The graft ratio of the system using benzophenone as initiator in the presence of 1.2 Tesla of external magnetic field is more than three times than in the absence of magne tic field.

但是无论是用二苯甲酮、蕙醒还是安息香作为引发剂，异戊二烯的相对接枝率都相当低，一般不超过40多。

The reducing-coupling reaction of benzoyl chloride under Dy/n-BuBr was complex. Besides diphenyl diketone, benzoin and ring-opening product of THF were also obtained.

苯甲酰氯在Dy/n-BuBr作用下的还原偶联反应较为复杂，除得到二苯基乙二酮外，还得到四氢呋喃开环产物以及安息香。

The essential oils which are suitable to blend with it: Basil, benzoin, black pepper, cypress, olibanum, geranium, jasmine, lavender, lemon, myrrh, orange blossom, rose and cananga odorata.

其他适合与之调和的精油：罗勒，安息香，黑胡椒，丝柏，乳香，天竺葵，茉莉，熏衣草，柠檬，没药，橙花，玫瑰，依兰。

Results of sampling showed that the typical evergreen broad-leaved forest of Mt. Jiulianshan consisted mainly of subtropical families and genera with dominant families including Fagaceae, Lauraceae, Camelliaceae, Styracaceae, Ericaceae, and Magnoliaceae.

群落主要由热带、亚热带科属组成，优势科为壳斗科Fagaceae，樟科Lauraceae，山茶科Camelliaceae，安息香科Styracaceae，杜鹃花科Ericaceae和木兰科Magnoliaceae等科，优势树种以相应的优势科属树种为主。

Deoxybenzoin(3) was prepareded by using the resorcinol and substituted phenylacetic as starting meterials in microwave-mediated.Then the compound(3) was reacted with acetic anhydride to produce(4).The compound(4) was hydrolyzed to convert compound(5) in the acid-mediated. The compound(5) was reacted with the 1,2-dibromo-ethane and 1,3-dibromo-propane in refluxed condition with acetone as solvent to give(6) or(7),respectively.Lastly,the title compounds were synthesized by refluxing(6) or(7) with 2-methyl-benzimidazole and potassium carbonate in acetone solution.

以取代苯乙酸和间苯二酚为起始原料，用微波辐射法合成脱氧安息香(3)，(3)与乙酸酐缩合生成2-甲基-7-乙酰氧基异黄酮(4)，(4)在酸性条件下水解生成相应的异黄酮(5)，化合物(5)分别与1，2-二溴乙烷和1，3-二溴丙烷反应生成(6)和(7)，化合物(6)和(7)再分别与2-甲基苯并咪唑偶合生成目标化合物。

This research utilizes the method of organic synthesis to put different amount of aminophenol into hydroxybenzoic acid or caffeic acid so as to produce a series of high yield of polyhydroxy benzamides (1~40).Through the following different activity tests, discussing the applied value of cosmetics.Ⅰ.

摘要 本研究主要利用有机合成方法，将具有不同数量及在不同位置之羟基取代之安息香酸及咖啡酸分别与胺基苯酚化合物进行醯胺化反应，得到一系列高产率之多酚醯胺类衍生物(1~40)，经由下列不同活性测试方法，探讨其化菻~上的应用价值。
