What are the chemical methods for distinguishing tripene and steroid side effects?
The chemical method to distinguish tripenoid and steroid were as follows: 1. Acetic anhydryride-concentrated sulfuric acid reaction: Dissolve the sample in sulfuric acid and add a few drops of concentrated sulfuric acid-sulfuric acid (1: 20). There will be color changes such as yellow, red, blue, purple, and green. The final color of the triterpene side was red or purple, and the final color of the steroid side was blue-green. 2. Trichloraconic acid reaction: drop the chlor form solution containing the sample of the steroid soap on the filter paper, add 1 drop of the chlor form solution, heat it to 60 ° C, and the red color will gradually turn purple; under the same conditions, the triterpene soap must be heated to 100 ° C to develop color, and the red color will also gradually turn purple, which can be used for paper purification to identify the two. 3. Aromatic Aldene-Sulfuric Acid/PerCloric Acid Reaction: Among the color reactions using aromatic aldenes, vanilin is the most common. Its color development is sensitive and often used as a color reagent for steroid side. In addition to vanilin, there is also p-Dimethylazinodimethylethylbenz aldehyde. 4. Antimony pentachloride reaction: dissolve the soap sample in either chloride-based or alcohol-based solution, then put it on the filter paper, spray it with 20% chloride-based solution of sulfur pentachloride (should not contain alcohol and water), dry it, heat it at 60 - 70 ° C, and blue, grayish-blue or grayish-purple spots appear. 5. Periodic acid-p-paranitraniline reaction, potassium iodinate reaction, the Trichloroactic acid reaction in the Magnesium-Sulfuric acid reaction and Molish reaction could also be used to distinguish the two. Dropping the chloride-based solution of the steroid soap sample on the filter paper, adding 1 drop of Trichloroactic acid test solution, heating to 60 ° C, the red color gradually turned purple; The triterpene soap must be heated to 100 ° C to develop color, and the red color also gradually turned purple. 6.

What are the effects of chemical reduction agents?
The chemical reduction agent had many uses: 1. In the field of soil and underground water restoration, for example, for the restoration of hexa-valent chromium-contaminated soil, chemical reducing agents could reduce hexa-valent chromium-contaminated soil, which was highly biotoxic and easy to migrate, to hexa-valent chromium-contaminated soil, which was much less biotoxic than hexa-valent chromium-contaminated soil and less mobile. However, there were some problems in the underground environment. For example, after the dissolved and exchanged hexavalent chromiums were reduced, the hexavalent chromiums in the bound state of iron and manganite may be released into the underground water again. Moreover, the widely existing oxiding substances in the soil such as manganite would quickly vaporize the chemical reducing agent, which may cause a "tailing" phenomenon. 2. In water treatment, the reducing agent is mainly used to remove residual oxygen and oxidiser in water to prevent oxidization, decomposition and pollution of water quality. The details are as follows: - By reacting with the oxygen in the water, the oxygen is reduced to water, thereby reducing the concentration of oxygen in the water, preventing the oxygen from oxidising other chemicals in the water, and reducing water pollution and damage. - It can eliminate the residual chorine in the water and react with the residual chorine in the water to reduce the damage to the human body and the environment, and improve the safety and health of the water quality. - It can remove the chemical intermediate and react with the intermediate produced by the chemical substances with a certain half-life in the water to avoid the harm of these intermediate to the environment and human health. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
