Chapter two: Using 5-(4-aminophenyl)-10,15,20-triphenylporphyrin as thestarting compound, the classical diazotization of aniline and the resulting reaction ofdiazo salts were applied to porphyrin for the first time, and a series of asymmetriclysubstituted meso-tetraarylporphyrins including 5-(4-chlorophenyl)-10,15,20-triphenylporphyrin, 5-(4-iodinphenyl)-10,15,20-triphenylporphyrin, 5-(4-cyanophenyl)-10,15,20-triphenylporphyrin, 5-(4-bisphenyl)-10,15,20-triphenylporphyrin and 5-(4-hydroxylphenyl)-10,15,20-triphenylporphyrin were synthesized.

第二章：在已合成的5-(4-氨基苯基)-10，15，20-三苯基卟啉基础上，首次将芳胺的重氮化及重氮盐反应应用于卟啉，合成了5-(4-氯苯基)-10，15，20-三苯基卟啉、5-(4-碘基苯基)-10，15，20-三苯基卟啉、5-(4-氰基苯基)-10，15，20-三苯基卟啉、5-(4-联苯基)-10，15，20-三苯基卟啉和5-(4-羟基苯基)-10，15，20-三苯基卟啉等一系列不对称取代的meso-四芳基卟啉。

The results showed that, both diene and alkaline nitrogen-containing compounds had negative influence on the aromatization stability of the catalyst.

用小型固定床加压反应器研究了液化石油气（C4 LPG）中的丁烯在纳米ZSM-5型催化剂DLG-1上的低温芳构化反应，重点考察了原料中二烯烃和碱性氮杂质，以及反应温度、压力和C4 LPG进料重量空速条件对催化剂芳构化反应活性及稳定性的影响。

The influence of each condition on the reaction speed and yield was studied, and the optimal conditions were: the ratio of the amount of substance of aromatic amine and heptafluoro-isopropyl iodine was 1:1.1~1.5, the amount of substance of sodium dithionite, sodium bicarbonate, aniline compounds were respectively 1.1~1.3, the amount of substance of phase transfer catalyst TBAB and aniline compounds was 0.05~0.1, the concentration of aniline compound was 0.5~1.0 mol/L, reaction temperature was 10~20 ℃, and the solvent was aether.

最佳结果为：芳胺与七氟异丙基碘的物质的量比1：1.1~1.5，连二亚硫酸钠、碳酸氢钠与苯胺的物质的量分别为1.1~1.3，相转移催化剂四丁基溴化铵与苯胺的物质的量比在0.05~0.1，溶剂总用量使苯胺浓度在0.5~1.0 mol/L；反应温度10~20℃；溶剂采用乙醚。取代基供电子性越强，反应时间越短，产率越高；氨基的对位优先反应，氨基的邻位较难发生反应；且七氟异丙基总是优先取代在芳环电子云密度较高的位置上。

Have had the intense function fromthis the explanation preparation and DNA, matched the body the planearyl residue groups and bases to insert the DNA double spiral plane,caused the plane aryl residue groups and bases the electronic clouddensity to have the change.

由此说明配合物和DNA发生了强烈作用，配体的平面芳基基团插入了DNA的双螺旋平面，导致平面芳基基团的电子云密度发生改变。

In addition, ioding was found to be an efficient catalyst for the imino Diels-Alder reaction of N-arylimine and enol ethers and the reaction provided tertrahydroqinolines in good yields. One pot synthesis of tetrahydroqinolines from aldehyde, aniline and enol ethers was also achieved using iodine as the catalyst. The chemical yield of the"one pot"reaction was comparable with that obtained using preformed N-arylimine.

此外我们也发现碘能够有效地催化N-芳基亚胺与烯醇醚的Diels-Alder反应，以很高的化学收率得到了四氢喹啉衍生物，并且发现碘也能够直接催化芳香醛、苯胺、烯醇醚的三组分"一锅"反应，获得的化学产率与使用预制的N-芳基亚胺相当。

The net photosynthesis rate and water utilization ratio in all treatments could be expressed by two-humped curve easily it had close co-relationskip with the natural characters of Euonymus fortunei and environment factors.

各处理的扶芳藤光合速率和水分利用效率都呈明显的双峰曲线，这与扶芳藤特性和环境因子的日进程密切相关。

A fumigation of aromatic oil of Litsea Cubeab was used to discharge the pollution aflatoxin B_1 from Euryale feroe Salisb. The results showed that the contents of aflafoxin can decline from 30 ppb to 10 ppb by the treatment of fumigation at the temperature of 40—50℃. in 72 hours, and that the effectiveness of detoxification was 66.7%.

本文采用山苍子芳香油熏蒸法，对自然污染黄曲霉毒素B_1的芡实进行去除实验，试验结果表明：在40°—45℃下，用山苍子芳香油，对自然污染黄曲霉毒素B_1的芡实，熏蒸处理72小时，可使芡实中黄曲霉毒素B_1由30PPb下降到国标10PPb，解毒效果达66.7%。

It showed that main constituents are linalool, geraniol, farnesol , safrole, citral, t-anethole , decanal and lauric aldehyde respectively and with high cont.

从它们的利用部位花、果、叶和根中，可提取芳香油，主要成分分别为芳樟醇、香叶醇、金合欢醇、黄樟素、柠檬醛、茴香醚及癸醛、十二碳醛等，含量相当高，为重要调香原料，有的作药用，颇具发展种植和开发利用价值。
