What Is an Indole?

Indole is a compound in which pyrrole and benzene are connected in parallel. Also known as benzopyrrole. There are two ways of combining, called indole and isoindole. Indole and its homologs and derivatives are widely found in nature, mainly in natural flower oils, such as jasmine, bitter orange, daffodil, and vanilla. For example, indole was first derived from the degradation of indigo; indole and its homologues also existed in coal tar; essential oils (such as jasmine oil, etc.) also contained indole; feces contained 3-methylindole; many Dyes are derivatives of indole; tryptophan, an essential amino acid of animals, is a derivative of indole; certain natural substances with strong physiological activities, such as alkaloids, auxins, etc., are derivatives of indole. Indole is an imine with weak basicity; double bonds of heterocycles generally do not undergo addition reactions; dimerization and trimerization can occur under the action of strong acids; under special conditions, aromatic electrophiles can be performed In the substitution reaction, the hydrogen at the 3-position is preferentially substituted. For example, the reaction with sulfonyl chloride can obtain 3-chloroindole. A variety of reactions can also occur at the 3-position, such as the formation of Grignard reagents, condensation with aldehydes, and Mannich reactions.

Indole and its homologs can be synthesized in a variety of ways, with

Natural products are widely contained in bitter orange flower oil,

Indole derivatives are widely distributed in nature. Many natural compounds contain indole rings in their structures. Some indole derivatives are closely related to life activities.

If there is a high concentration of indole in the body, the body will naturally let it excrete indole from the body, and it is very scary.

High concentrations of indole can emit tens of meters, and in the case of high fever and sweat, bad odor will be generated. ^[2]

Take hot baths more often, but not for patients with high concentrations in the body. Regulating nerves and psychology is fundamental, but it is difficult for patients. So first of all, we need to improve sleep. The content of indole in deep sleep is extremely low, and there is almost no body odor, but a lot of indole is released as soon as we wake up.

We can decompose indole and unpleasant odor from outside the body.

Adsorption of indole and pyridine in water by pitch-based spherical activated carbon (PSAC), coal columnar carbon (EAC), and coconut shell granular carbon (GAC). The adsorption isotherms and adsorption kinetics of three activated carbons for indole and pyridine were measured. Learn the curve. The results show that the removal rates of indole by all three activated carbons can reach 100%; the removal rate of pyridine by PSAC and EAC is about 82%, and the removal rate of pyridine by GAC is about 92%; The maximum rate. The adsorption performance of activated carbon is determined by the structure of the activated carbon and the molecular properties of the adsorbate. The richer the micropores, the better the adsorption performance; the more mesopores, the smaller the mass transfer resistance of the adsorbent molecules and the higher the adsorption rate; the smaller the solubility of the adsorbent molecules in water, the stronger the affinity of the activated carbon, and the larger the adsorption capacity , The better the adsorption effect. The adsorption of indole and pyridine by three kinds of activated carbon conforms to the Freundlich formula, and the formula parameters are determined. The larger the parameter a in the Frendlich formula, the smaller the 1 / n, the larger the activated carbon adsorption capacity; Faster.

Therefore, if you wear carbon fiber clothes, you can reduce body odor.

The only way to completely remove the exaggerated body odor is to regulate the nerves. ^[2]
