安息香的

by summarizing and analysing the progress on studies of pharmacodynamic material basis of resuscitation-inducing aromatic herbs such as moschus,borneolum syntheticum,styrax,benzoinum, and exploring the generality of those herbs,to provide scientific reference for further studies on the relevance of common substance ,nature and the efficiency of restoring consciousness and inducing resuscitation of those herbs.the result indicates that those four resuscitation-inducing aromatic herbs mainly contain volatile oil ,and all contain alicyclic compounds; the volatile oil of borneolum syntheticum and styrax both contain sesquiterpenes of caryophyllene; as resin herbs , styrax and benzoinum both contain vanillin, resin ester and balsamic acid .

通过对芳香开窍药麝香、冰片、苏合香、安息香的药效物质基础研究进展的整理、分析，探索其共性，拟为深入研究该类药的共性物质—药性—开窍醒神效应之间的关联性提供科学参考。结果表明，四味芳香开窍药主含挥发油，均含有脂环化合物，并存在一些共有成分，如龙脑冰片与苏合香挥发油中均含有倍半萜类成分石竹烯；苏合香和安息香皆为树脂类中药，两者均含有香荚兰醛成分，尚含树脂酯，香脂酸等。

Cu complex of the surfactant have water soluble ability and surface activity, can catalyze the air oxidation of benzyl alcohol or Benzoin not only in DMF solution but also in alkali water solution.

表面活性剂铜配合物具有较好的水溶性和表面活性，不但在DMF溶剂中有效催化苯甲醇、安息香的空气氧化反应，而且在稀碱溶液中形成的金属胶束也可催化氧化苯甲醇。

The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。

Furthermore, different methods of storage and preservation (1.0% benzoic acid, 1.0% sorbic acid, 0.05% and 0.5% dialdehyde starch) were compared to conventional preservation procedures.

此外， 存储和保存的不同的方法(1.0%安息香的酸， 1.0%山梨酸， 0.05%并且0.5% dialdehyde淀粉)与常规的保存过程相比。

Results and Discussion Flavin 2 was synthesized from 3,4-diaminobenzoic acid (3) and alloxane monohydrate (4) in good yield according to standard procedures (Scheme 1).9 The first step afforded flavin 5 in quantitative yield, in 1:1 ratio of the 7- and 8-hydroxycarbonyl regioisomers, and was subsequently methylated by methyl iodide to form flavin 6 in 86% yield, in a 3:2 ratio of the 7- and 8-regioisomers.

结果与讨论黄素二是合成3，4 -二氨基安息香的酸（ 3 ）和氧嘧啶水合物（ 4 ）在良好的收益率根据标准程序（计划1） 0.9的第一步，给予黄素五，在定量产量，在1：1的比例， 7 -8 -羟基羰基 regioisomers ，并随后甲基甲基碘形成黄素6月在86 ％的产量，在一个3：2的比例， 7 -和8 regioisomers 。

This thesis is constituted by four parts: In the first part a summarization is given on the main total synthetic methods of isoflavones, for example, deoxybenzoin method which generally involves two steps wherein a phenol is reacted in the presence of a Lewis acid with phenylacetic acid to generate an intermediate deoxybenzoin which is then cyclized with a one carbon electrophile.

本论文主要工作包括四部分：第一章综述了近年来全合成异黄酮的主要方法：脱氧安息香法，是以多羟基苯酚与苯乙酸或苯乙腈在Lewis酸存在下，反应生成中间体脱氧安息香，然后再与亲电碳试剂进行关环反应生成异黄酮。
