The extraction and application of ethyl acetate in the pharmaceutical industry

In the south of Guangdong, there is a factory in Gongyi called Hongdong, and there is a factory in its place, named Hongdong Chemical. It is good at chemical technology and is good at the pharmaceutical industry. In the factory, ethyl acetate is often used as the essential agent for drug extraction, which is used in pharmaceutical industries, and its use is great.

In the process of Guanfu Pharmaceutical, the material is complex and impurities are numerous. If you want to obtain pure medicine, the extraction method is the common way. Ethyl acetate is specific and can be divided into different substances, unlike good and bad. Its nature is mild, and it does not damage its effect in the quality of various medicines, but helps its purity.

In the system of herbal medicine, herbal medicine contains many kinds of ingredients, which are useful and useless mixed. Extract it with ethyl acetate, you can take its essence and discard its dross. If you get spiritual grass, mash it and put it in a kettle, and use ethyl acetate to replenish it. Over time, ethyl acetate can dissolve the beneficial qualities in herbs, such as active ingredients and alkaloids, while impurities remain in the solid form. Pour its liquid and steam its esters, and the essence of the medicine is obtained, pure and effective.

Pharmaceutical matters are related to human life, so the pursuit of purity is extremely demanding. Ethyl acetate can make the quality of the medicine highly purified when extracting the medicine. Its selectivity is good, and it can dissolve the required medicine without impurities. And its boiling degree is suitable. After extraction, it is easy to remove by distillation, leaving no residual damage in the medicine. < Br >
In comparison with other agents, water is a common solvent, but water has strong polarity, and the extraction power is weak for some fat-soluble medicinal substances. Although alcohols also have the ability to extract, they may react with the drug quality and change their properties. Ethyl acetate is not the same. Its properties are stable, and it does not respond to the drug quality. It also has the ability to extract the drug quality that is fat-soluble and water-soluble.

The craftsmen in the factory, according to the nature of the drug, choose the amount of ethyl acetate and control the temperature at the time of extraction. The quality of the drug is different, and the method is also different. Or leaching at room temperature, or heating and quick extraction, all seek the purity and effect of the drug.

The factory of Hongdong has been using ethyl acetate for the extraction of pharmaceuticals for a long time. The medicine produced is used in all directions, and is valued by doctors and relied on by patients. Craftsmen study their skills in the hope of using this good medicine in a better way, and use this good medicine to make more good medicine and help the suffering of the world.
