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 process is carried out by taking organic acid and sulfoxide chloride as raw materials, acyl chloride synthesizing, reacting ethylenediamine with sodium chloroacetate to synthesize intermediate sodium EDDA, and reacting it with acyl chloride to synthesize the final product.

所述双子烷基羧酸盐表面活性剂是由以下方法制得的，以有机酸和氯化亚砜为原料首先进行酰氯的合成，再用乙二胺与氯乙酸钠反应合成中间体乙二胺二乙酸钠，将中间体乙二胺二乙酸钠与酰氯反应合成终产物。

C. I. Reactive blue KN-R, Alizarin brilliant green G and Hostlam blue R could not be degraded by Zoogloea HP3. Furthermore, ABAS degradation was regressed under the exisitence of the above dyes. 1-Aminoanthraquinone-2sulfonic sodium, 1, 4-dihydroxylanthraquinone-2-sulfonic sodium, 1, 4, 5, 8tetrahydroxylanthraquinone, anthraquinone, aniline, phenol, catechol and ophthalic acid could be degraded by Zoogloea HP3. Aniline was the most degradable substrate among ABAS, aniline, phenol, catechol and o-phthalic acid. However, benzenesulfonic sodium and p-amino benzenesulfonic sodium were not degraded by it.

动胶菌HP3不能降解活性艳蓝KN-R、弱酸性绿GS及毛用活性蓝HW-R等蒽醌型染料，且染料的存在对菌体降解溴胺酸有不同程度的抑制作用；动胶菌HP3可以降解1-氨基蒽醌-2-磺酸钠、1，4-二羟基蒽醌-2-磺酸钠、1，4，5，8-四羟基蒽醌、蒽醌及苯酚、邻苯二酚、苯胺、邻苯二甲酸等苯系化合物，而不降解苯磺酸钠、对氨基苯磺酸钠；在溴胺酸、苯酚、邻苯二酚、苯胺、邻苯二甲酸中，苯胺是动胶菌HP3的天然底物。

RESULTS:In the Chenxiang Lubailu table,the identification of bismuthic salt positive result with dilute nitric acid instead of hydrochloric acid and the white precepitation formed in identification of magnesian was bismuth hydroxide sediments,it was easy and accurate to identify bismuthic salt by adding ascorbic acid.

结果：该片中的铋盐碘化钾鉴别反应，用稀硝酸代替盐酸做溶剂，呈正反应；镁盐氯化铵-磷酸氢二钠鉴别反应，加氨试液后，析出的白色沉淀不是Mg2，而是Bi3，该沉淀在氯化铵试液中不溶，干扰镁盐鉴别；铋盐含量测定项，用加抗坏血酸掩蔽剂的方法，排除Fe3+的干扰，使终点颜色稳定，易于准确判断。

A method of new type phosphate-free detergent builder- crystalline layered sodium disilicate with sodium sulfate producing water glass was studied,and the effects of impurities to quality in the raw material were explored.

The lowest surface tension of N_xB solution was better at 25℃, and lowest surface tension would down with carbon . cmc( critical micelle concentration) and γ_ in N_(12)B are 4.1 × 10~(-4)mol/L, 24.5 mN.m~(-1),what was smaller than LAS . The cmc of N_(12)B- NaCl are down with NaCl up.The surface tension and cmc of N_(12)B and N_(16)B are higher than that of N_(12)OB and N_(16)OB because of hydrophilic group ,but that of N_(12)B is lower than that of N_(16)B because of hydrophobic group .5. The borate structure and semipolar bond were studied in different pH by infrared spectrum .It indicated that N_xB and N_xOB have not semipolar bond at pH

4、25℃，N_xB系列都有较低的表面张力，并随碳原子数的增加而最低表面张力下降。N_(12)B比同碳原子数的十二烷基苯磺酸钠的最低表面张力34.5mN／m低，且临界胶束浓度为4.1×10~(-5)mol／L，也比LAS低，且随着NaCl浓度的增加而略有下降，比较N_(12)B和N_(16)B，由于C_(16)疏水基的异构体使N_(12)B的临界胶束浓度和临界胶束浓度时的表面张力γ_(cmc都低，由于增加了亲水基团使得N_(12)OB和N_(16)OB的表面张力和临界胶束浓度都要高于N_(12)B和N_(16)B。
