Chapter two 4-Hydroxybenzoic acid is connected with PEG6000 through defoliant DCC at rooom temperature, then the product is refluxed with chloroacetic acid in acetone to afford PEG-bound phenyloxyacetic acid, which is reacted with thionyl chloride, ammonium thiocyanate and arylamines in turn to give PEG-bound disubstituded thioureas. After the cleavage with sodium methoxide in methanol, the eleven disubstituted thioureas are obtained.

第二章 利用PEG6000作载体，通过脱水剂DCC在室温下将对羟基苯甲酸以酯键连接在PEG6000上，再与氯乙酸在较温和的条件下生成PEG6000支载的芳氧乙酸，然后，依次与亚硫酰氯、硫氰酸铵、芳胺反应，生成PEG6000支载的硫脲，最后用甲醇钠的甲醇溶液切割PEG，得到了十一种1，3-二取代硫脲。

The results of in vitro culture show that sodium fumarate increased NDF digestibility, total volatile fatty acid concentration and propionate proportion, decreased ammonia concentration, and acetate, butyrate, and valerate proportions, and acetate to propionate ratio when using bermudagrass hay as the substrate.

体外培养的结果显示，当使用百慕达乾草为受质时，添加延胡索酸钠，提高了中洗纤维消失率、总挥发性脂肪酸浓度和丙酸的百分比，降低了氨浓度、乙酸、丁酸和戊酸的百分比，乙酸对丙酸的比例降低。

It demonstrated that the hydroxy organic acids substituted with-OH,-SH at α—C such as lactic acid, Hydroxy-acetic acid, mercapto-acetic acid, glyconic acid have good selectivity for separation of hematite and aegirine pka values of organic acids fall down because of the-I inductive effect of-OH or-SH, and lie at the pH range between two minerals point-zero-charge. As a result, the depression ability of them was enhanced, and a cyclo-pentyl chelate was formed when this organic acids acted with Fe〓 on the minerals surface.

发现在α位具有-OH、-SH等取代基的短链一元羧酸（乳酸、羟基乙酸、巯基乙酸，葡萄糖酸）对赤铁矿与钠辉石的浮选分离具有优良的选择性抑制作用，-OH、-SH的-I诱导效应导致有机酸的pKa值下降并落在两种矿物零电点之间，使其抑制性能增强，并与矿物表面的Fe〓形成稳定的五元螯合环。
