In this paper, firstly using natural fatty acids including lauric acid, myristic acid, palmitic acid etc. and disproportionated rosin as starting materials, the acyl reaction of starting materials with SOCl_2 respectively, and then using Schotten-Baumann condensation: on the reaction conditions of alkalescence, condensation of acylchloride with amino acid (sarcosine, glycine, alanine etc.), and then acidification, saltation. A series of anionic surfactants of N-acyl amino: sodium N-fatty acyl sarcosinate (SFS-12, SFS-14, SFS-16); sodiun N-fatty acyl glycinate(SFG-12, SFG-14, SFG-16); sodium N-fatty acyl alaninate(SFA-12, SFA-14, SFA-16)and sodium N-disproportionated rosinoyl aminatewere prepared. During the preparation of N-acylamino acid, the reaction conditions of acylchloride with amino acid condensation were identified by optimizing the synthetic conditions of N-lauroyl sarcosine: mol ratio of amino acid to acylchloride 2:1, reaction taken place in a solvent composed by acetone/water 2:1, acylchloride and 20% NaOH were slowly added to the reaction mixture at the same time while maintaining the pH at 9~10, after completion of adding maintaining reacting for 2.5h at 25℃.

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中，当硝酸锌浓度低於0.1 M 时，氧化锌以(002)面为优选位相，当浓度提高，其他晶面将会出现，当硝酸锌为0.06 M，(002)晶面成长最佳，分别加入乳酸和柠檬酸，乳酸结构上有一羧基团而柠檬酸有三个羧基团，单芽基的乳酸有助於氧化锌成长，对照於三芽基的柠檬酸，则必须在极低的浓度下才能制备氧化锌薄膜，但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。

第三，通过脂松香与丙烯酸加成合成了丙烯酸松香，该反应是左旋海松酸与丙烯酸发生Diels-Alder加成反应生成丙烯海松酸，由于脂松香中的枞酸型树脂酸在高温下处于异构化平衡状态，因此随着反应的进行枞酸、长叶松酸等会异构化为左旋海松酸参与反应。
