Sodium cyclohexanoloxyacetate was synthesized by 1mol︰1.15mol of cyclohexyl sodium alcoholate to sodium chloroacetate at 135145℃.The reaction time was 2.5h and the yield was about 81%.The sodium cyclohexanoloxyacetate was acidified by HCl to get the intermediate product,2-cyclohexanoloxyacetic acid.

以摩尔比为1︰1.15的环己醇钠和氯乙酸钠为原料，在135145℃下反应合成了环己氧基乙酸钠，反应时间为2.5h，收率约为81%，再将环己氧基乙酸钠用盐酸酸化制得中间体环己氧基乙酸。

The experimental results show that the transfer volumes for these amino acids from water to sodium acetate, sodium butyrate, sodium caproate, sodium caprylate and guanidium hydrochloride solution are positive and increase with the increasing concentration of denaturant The standard partial molar transfer volume of zwitterionic end group (NH〓, CO0〓) are larger positive values and the corresponding values of methylene group CH〓 are smaller and negative.

实验结果表明，氨基酸从水到乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液的标准转移偏摩尔体积为正值，且随变性剂浓度的增加而增大；氨基酸的两性端基的标准转移偏摩尔体积为较大的正值，而CH〓基团标准转移偏摩尔体积为较小的负值。

Objective To study the interaction of bile salts, namely sodium taurocholate, sodium tauroglycocholate, sodium deoxycholate and cow sodium cholate, with Cu2+ in acetic acidsodium acetate buffer.

目的 研究弱酸性介质中，牛磺胆酸钠、甘牛胆酸钠、胆酸钠和脱氧胆酸钠等4种胆酸盐与Cu2+离子相互作用。

Optical microscope, scanning electron microscope and X-ray diffraction analysis have revealed that dawsonite mainly occur in the feldspar-rich sandstone and pyroclastic rocks, either as cements filling inter-grain pores as radical, bunchy, rosette, intricately trichoid, and platy collectives, or as replacement of feldspar and lithic grains with bunchy and paty shapes.

片钠铝石主要发育在油气储层或CO2气储层中富含长石的砂岩和火山碎屑岩中。在含片钠铝石砂岩和火山碎屑岩中，片钠铝石以放射状、束状、杂乱毛发状、球状和板状等集合体充填孔隙，或呈束状和板状交代长石和岩屑。片钠铝石及其共生的铁白云石都是最晚形成的自生矿物组合。

Values of hydration number of amino acids have been calculated at different temperature and concentration of denaturant. It is found that they decrease with increasing temperature and concentration of denaturant. Denaturant and increasing temperature have cooperative dehydration effect on amino acids.

计算了不同温度和变性剂浓度下氨基酸在乙酸钠、丁酸钠、己酸钠、辛酸钠和盐酸胍水溶液中的理论水化数，发现它们随变性剂浓度的增加和温度的升高而减小，说明变性剂和升温对氨基酸有协同脱水作用。

The results show that 5% nucleating agent,twelve-hydrated disodium hydrogen phosphate,could reduce the supercooling degree of acetate hydroxide trihydrate to some extent but the supercooling degree was still large.However,the supercooling degree of sodium acetate trihydrate could decrease clearly by adding 3% thickener gelatin and 5% twelve-hydrated disodium hydrogen phosphate.

实验结果表明，质量百分比为5%的成核剂十二水磷酸氢二钠能一定程度上抑制无机水合盐三水醋酸钠的过冷度，但其过冷度仍然较大；使用质量百分比5%的十二水磷酸氢二钠和质量百分比3%的增稠剂明胶做添加剂后，三水醋酸钠的过冷性能得到明显改善。

After the coagulation and sedimentation in the jar test with ferric chloride, the residual COD in the supernatant was 9000 mg/L which was further oxidized by chloric acid or with Fenton method. The COD removal efficient increased with the increasing of the dosage of chloric acid from 0.5 ~ 100 g/L or the H2O2/Fe2+ from 5/2.5 ~ 50/25 g/L, and the economical dosage were suggested as chloric acid 50 g/L or the H2O2/Fe2+ 50/25 g/L which resulted in the residual COD of 400 and 3300 mg/L individually for 95 and 63 % COD removal percentages. Oxidation test showed that only 5 minutes was needed for 92 % COD removal in the case of chloric acid dosage 50 g/L.

废液A经氯化铁混凝沉淀后，COD浓度可降低至9，000mg/L，仍未符合符合工业区污水厂进厂限值(＜650mg/L)，进而使用氯酸钠直接氧化法及Fenton法以去除剩余之COD，其操作条件范围分别为氯酸钠加药量0.5g ~ 100g/L ，而最适加药量为50g/L，及Fenton法H2O2/Fe2+加药量范围为5/2.5g/L~50/25g/L，其最适H2O2/Fe2+加药量为50/25g/L，两种方法处理后残余COD浓度分别为400mg/L及3300mg/L，去除率约为95%及63%，而依此判断氯酸钠氧化处理残余COD有较好之效果，且利用氯酸钠氧化速率快，5分钟就能有92%去除率，所需水力停留时间较短，由此实验建议利用氯酸钠直接氧化处理，最适加药量为50g/L。
