Description

Technical Field

[0001] The utility model relates to the technical field of p-nitrobenzyl alcohol production equipment, in particular to p-nitrobenzyl alcohol purification equipment. Background Art

[0002] p-Nitrobenzyl alcohol, also known as 4-nitrobenzyl alcohol and p-nitrobenzyl alcohol, is readily soluble in ethanol and ether and slightly soluble in cold water, with a solubility of 1% in water at 25°C and 10% at 100°C. It is a raw material for organic synthesis and widely used as a pharmaceutical synthesis intermediate. It can also be used in the production of synthetic resins, coatings, fluorescent dyes, and other organic chemical raw materials. It is used to prepare organic glass monomers, di-p-nitrobenzyl alcohol, hexylene glycol, methyl isobutyl ketone, methyl isobutyl carbinol, phorone, isophorone, chloroform, iodoform, and other organic chemical raw materials. It is used as an excellent solvent in coatings, acetate fiber spinning processes, acetylene storage in cylinders, and dewaxing in the oil refining industry. In cosmetics, it is used in the manufacture of nail polish. As a low-boiling-point solvent, it can reduce the viscosity of nail polish and has quick-drying properties.

[0003] In the existing technology, it is inconvenient to discharge the p-nitrobenzyl alcohol in the purification kettle during the purification process of p-nitrobenzyl alcohol. This will cause a large amount of p-nitrobenzyl alcohol to adhere to the inner wall of the purification kettle and make it difficult to remove the p-nitrobenzyl alcohol. Finally, the guide column reduces the purification efficiency of p-nitrobenzyl alcohol. Therefore, we propose a p-nitrobenzyl alcohol purification device. Utility Model Content
