酚磺酸

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.

将水杨醛与碱和氯甲基甲基醚反应，再经过NaBH4还原，即制得邻苯甲醇，然后将其在DMF中与NaH和二甘醇二对甲苯磺酸酯反应，得开链冠醚1a和1b.1a和1b经稀酸水解，即脱保护而分别生成新的酚型开链冠醚2a和2b。

Although sulfuric group can ionize at any pH value, but the ionization degrees of carboxylic and phenolic group in the solutions increase with increasing pH values.

磺酸在所有pH范围完全电离，但羧酸和酚羟基的电离程度随溶液pH降低而减少。

In this article, different soft templates formed by sodium bis (2-ethylhexyl) sulf-osuccinate, nonyl phenol polyethyleneoxy ether (Oπ-10) and cetyltrimethyla- mmonium bromide were used to fabricate CaCO3, BaCO3 and CeO2/CuO nanoparticles with different morphology.

本文分别利用丁二酸二(2-乙基己基)酯磺酸钠、壬基-酚基-聚乙氧基醚（Op-10）和十六烷基三甲基溴化胺形成的不同软模板合成了具有不同形貌的CaCO3， BaCO3和CeO2/CuO纳米粒子。

RESULTS:In the case of ambient temperature cefoxitin with etamsylate is in compatibility steady-state both in compatible content and outward stability (P＞0.05) within 6h;cefoxitin with aminomethylbenzoic acid or adrenochromazone is in compatibility steady-state (P＞0.05) within 4h;cefoxitin with aminocaproic acid varies in compatible content (P＜0.05) after 4h.

结果：在室温条件下，头孢西丁与酚磺乙胺在0～6 h内含量(P＞0.05)和外观稳定，但pH值有变化(P＜0.05)；与氨甲苯酸、安络血在0～4 h内稳定(P＞0.05)；与氨基己酸配伍有变化(4 h后P＜0.05)。

OBJECTIVE:To study the compatible stability of levofloxicin hydrochloride injection with five kinds of homostatic(etamsylate, tranexamic acid , aminocaproic acid , aminome thylbenzoic acid , hemocoagulaser).

目的 ：研究盐酸左氧氟沙星注射液与五种止血药(酚磺乙胺、氨甲环酸、氨基己酸、氨甲苯酸注射液和注射用蛇毒血凝酶)配伍的稳定性。

The main intermediates were detected during decomposition,such as acetic acid,oxalic acid,malonic acid,phenol,3-hydroxyhypnone,naphthalene,benzene sulfonic acid,phthalic acid,β-naphthalene etc . by ultraviolet-visiblespectroscopy,ion chromatographand gas chromatograph coupled with mass spectrophotometertechniques.The possible degradation pathway of Acid Orange Ⅱ was also speculated,that was,hydroxyl radical reacted with the azo linkage-bearing carbon of naphthol-ring,and the C—N cleaved,the azo-dye decolored and mineralized.

运用紫外光谱、离子色谱、色谱-质谱联用等方法，测定出酸性橙Ⅱ的主要降解产物有乙酸、乙二酸、丙二酸、苯酚、3-羟基苯乙酮、萘、苯磺酸、邻苯二甲酸、β-萘酚等，并依此推测酸性橙Ⅱ的降解机理，即羟基自由基攻击酸性橙Ⅱ分子上与萘环相连的C—N键，导致C—N键的断裂，进而染料脱色矿化。
