Amino to acetyl phenol, in have technology of two kinds of production domestic and internationally, acetic anhydride craft of the United States, acyl changes temperature to have 75 ℃ only, acyl changes mother liquor not apply mechanically, deputy reaction is little, of production thick tasting is kind of white almost, purificatory craft is very simple, activated carbon dosage only 2~3%, the Kun that its product does not have glow material almost in different third alcohol inferior the sealed impurity of amine impurity and minim, settleclear lightness it may not be a bad idea, the product quality that acetic anhydride craft produces is good, but close rate low, cost is high.

对乙酰氨基酚，在国内外有两种生产工艺，美国的醋酐工艺，酰化温度只有75℃，酰化母液不套用，副反应少，生产的粗品几乎是类白色，精制工艺就非常简单，活性炭用量仅2~3%，其产品在异丙醇中几乎无红光物质的醌亚胺杂质及微量的未知杂质，澄明度也好，醋酐工艺生产的产品质量好，但收率低、成本高。

The single mechanical seals of five PHP pumps, nine PLA pumps, two THD pumps and nine ZA pumps in the acetic acid plant were changed into dual mechanical seals based on not changing main parts such as casing, impeller, shaft, bearings house etc. to solve the leakage problems of flammable, explosive, poisonous, harmful substances, such as acetic acid, methyl iodide, hydroiodic acid, and propionic acid etc.

通过对醋酸装置中所选用的5台PHP型、9台PLA型、2台THD型及9台ZA型单级卧式脚支撑化工离心泵，在不改变泵壳、叶轮、轴、轴承箱等主要部件的基础上，将原来的单端面机械密封改造为双端面机械密封或串联式机械密封，以此来防止所输送的易燃、易爆、有毒、有害高危介质（如醋酸、碘甲烷、碘化氢、丙酸等）外漏。

During the reaction,the bromide component has been converted to catalytically inactive benzylic bromide.In pure acetic acid medium,the "catalyst failure" occurs owing to the formation of benzylic bromide while in acetic acid-water medium,the solvolysis of benzylic bromide by water maintains the catalytic activity to some extent.

反应过程中溴组分会转变为无活性的苄溴，在纯醋酸溶剂中，催化剂会因苄溴的形成而发生催化剂失活现象；在醋酸-水混合溶剂中，由于水对苄溴的溶剂化作用会使苄溴还原为溴离子，一定程度上保持了催化剂活性；并且在一定范围内，含水量的提高有益于生成醛选择性的提高，研究表明，将混合溶剂的初始含水量控制在5-10wt。

Acetic: Wines, no matter how well made, contain quantities of acetic acidity that have a vinegary smell.

醋酸：不管多好的葡萄酒都含有一定量的醋酸，醋酸带有醋的味道。

If there is an excessive amount of acetic acidity, the wine will have a vinegary smell and be a flawed, acetic wine.

葡萄酒中含有的醋酸量不能超出一定的范围，最起码不能让葡萄酒闻着像醋。

The quantitation was monitored with an Inertsil ODS-3V column using a mobile phase of methanol- 0.3%acetic acid = 64:36 for TLM and acetonitrile- methanol - 0.3%acetic = 2:64:34 for Z detector set at 254nm.

对托美丁的分析方法是用Inertsil ODS-3V管柱，移动相则采甲醇： 0.3%醋酸为64： 36 ；而对佐美酸的定量亦用相同管柱，移动相为乙晴：甲醇： 0.3%醋酸为2： 64： 34，UV侦测器则同样设定为254 nm。

After the basis set superposition error correction and the zero point vibration energy correction, the interaction energies for three types of NMA-acetic acid complexes and one type of NMA-water complex were -44.3,-35.5,-32.4 and -16.0 kJ·mol-1 respectively, which showed that NMA had a great affinity for acetic acid than water.

NMA与水\醋酸之间都有氢键形成，经计算得到NMA-醋酸复合物的稳定化能在-32.4~-44.3kJ/mol之间，且平面构型的NMA-醋酸复合物稳定能较高，而NMA与单分子水的稳定化能仅为-16.0kJ/mol。
