丙酮的

I would like to ask Xuzhou where sales of acetone ah!

请问徐州哪里有卖丙酮的啊！

The typical industrial technology of producing phenol was cumene process containing four steps: alkylation,oxidation,purification and recovering.

异丙苯法是苯酚、丙酮的代表性工业制备方法，主要由烃化、氧化、精制、回收四个工序组成。

When the concentration of tested gases was 2000 mL/m3, chloroform, ethylene dichloride, formaldehyde and benzene did not interfere with the determination of acetone.

当各测试气体浓度均为2000 mL/m3时，三氯甲烷、二氯乙烷、甲醛和苯气体不干扰丙酮的测定。

Objective To determine the contents of residual acetone in acetoacetic ester,the raw material for the synthesis of Edaravone, by gas chromatography.

摘要］ 目的：用气相色谱法测定依达拉奉合成起始原料乙酰乙酸乙酯中丙酮的残留量。

Benzylidene acetone desorption potential acid sulfate tin plating solution is very close to the ideal desorption potential; Benzylidene acetone, formaldehyde can regulate the desorption potential role and can increase the current density range; Composite additive D can make acid sulfate tin plating solution in the hydrogen produced during the rapid detachment; Ammonium metavanadate can catalyze Sn4+ and restore to Sn2+, and then make solution stability.

苄叉丙酮的脱附电位很接近酸性硫酸盐镀锡溶液的理想脱附电位；甲醛具有调节苄叉丙酮脱附电位的作用，并且能够增大电流密度范围；复合添加剂D能够使酸性硫酸盐镀锡溶液在电镀过程中产生的氢气迅速脱离；偏钒酸铵能够催化Sn4+还原为Sn2+，从而使镀液稳定。

The illicit synthesis of this compound has been achieved most commonly by the reductive amination of phenyl-2-propanone 2, by the Leuckart formamidation of 2 followed by hydrolysis or by the reduction of ephedrine or pseudoephedrine 3 with hydriodic acid and red phosphorus.

此化合物非法合成的方法有，通过1-苯基-2丙酮的还原胺化作用；通过1-苯基-2丙酮的洛卡特氐反应后进行水解生成；在红磷、氢碘酸的参与下，通过还原麻黄素或伪麻黄素合成。

CoFe2O4 is sensitive to low concentration alcohol and acetone, for other gases it has not sensitivity, so this material may be used to inspect low concentration alcohol and acetone.

研究发现，CoFe_2O_4制作的元件对低浓度的乙醇和丙酮气体有较好的灵敏性，对其他气体基本没有气敏性，因此，该材料可用于上述两种气体的低浓度检测；在乙醇和丙酮的低浓度范围内，两种气体的浓度与该元件的灵敏度呈良好的线性关系。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
