Diethylene glycol, which is mild in nature and has a certain viscous state, is a colorless, transparent and odorless liquid at room temperature. It has a slightly sweet taste and can be miscible with many organic solvents such as water, ethanol, and acetone, but it is insoluble in ether, benzene, and carbon tetrachloride. Its boiling point is quite high, reaching 245 ° C. This characteristic makes it stable in many occasions that need to withstand higher temperatures.
Diethylene glycol has a melting point of -10.45 ° C. Its low melting point makes it mostly liquid at general ambient temperature, which is convenient for various process operations and use. Its relative density is 1.1184 (20 ° C), which is similar to water. Therefore, it is easy to disperse evenly in systems mixed with water.
In addition, diethylene glycol is hygroscopic and can absorb water vapor from the air. Due to its molecular structure containing hydroxyl groups, it has certain chemical activity and can participate in a variety of chemical reactions, such as reacting with acids to form esters, reacting with alcohols to form ethers, etc. This chemical activity is widely used in the field of chemical synthesis and can be used as a raw material or intermediate to prepare many chemical products such as plasticizers, lubricants, solvents, etc.
However, it should be noted that diethylene glycol has certain toxicity. If it is accidentally ingested or exposed for a long time, it will endanger human health. In the past, serious poisoning incidents have occurred due to accidental ingestion of medicines or foods containing diethylene glycol. Therefore, in the production and use of diethylene glycol, it is necessary to strictly follow safety procedures and take protective measures to ensure personnel safety and environmental safety.

2-% pentyne-propionic acid, also known as 2-pentyne-3-acid, is a member of the family of organic compounds. This substance has unique chemical properties and has a wide range of uses in the field of organic synthesis.
Looking at its structure, 2-% pentyne propionic acid contains two key functional groups, alkynyl group and carboxyl group. The presence of alkynyl group endows the molecule with significant reactivity. The alkynyl group has unsaturated characteristics and high electron cloud density of π, which is vulnerable to attack by electrophilic reagents or nucleophiles, triggering a variety of chemical reactions. For example, it can participate in classical electroaffinity reactions, such as when adding to hydrogen halides, following the Markov rule, hydrogen atoms tend to be added to alkyne carbon atoms containing more hydrogen to generate halogenated olefins. If conditions are suitable, it can be further added to generate halogenated alkanes. It can also react with some metal catalysts, such as under the catalysis of transition metals, to achieve the coupling reaction of alkynyl groups. This is an important means of building carbon-carbon bonds and is of great significance in the synthesis of complex organic molecules.
Carboxyl groups, as another important functional group, are acidic. Due to the conjugation effect of carbonyl and hydroxyl groups in carboxyl groups, the electron cloud of oxygen-hydrogen bonds in hydroxyl groups is biased towards oxygen atoms, and hydrogen atoms are easily dissociated in the form of protons, showing acidity. This acidic property allows 2-% valpropionic acid to neutralize with bases to form corresponding carboxylic salts. At the same time, carboxyl groups can also participate in many substitution reactions, such as acid-catalyzed esterification with alcohols to form ester compounds. This reaction is often used in organic synthesis to prepare fine chemicals such as fragrances and pharmaceutical intermediates.
In addition, there is an interaction between the alkynyl group and the carboxyl group in the molecule of 2-% valpropionic acid. The electronic effect of the alkynyl group changes the acidity of the carboxyl group, and the existence of the carboxyl group also affects the reactivity and selectivity of the alkynyl group. This synergy effect between functional groups provides organic synthesis chemists with more choices of reaction paths and strategies, which is helpful for the design and synthesis of organic compounds with novel structures and unique functions.

If you want to make Erchen soup, the method is as follows:
Use Banxia (wash the soup seven times), five taels each of orange red, three taels of white Poria cocos, and one or two halves of licorice (fried). On the mouth, four dollars per serving, one cup of water, seven slices of ginger, and one ebony, fried for six points at the same time, to remove dross, and take it hot, regardless of the time.
Banxia is dry and wet to reduce phlegm, reduce reverse and stop vomiting, eliminate ruffians and disperse knots; orange red regulates qi and stagnates, dry and wet to reduce phlegm, and the two are combined. It is an essential medicine for treating wet phlegm, and it is a medicine for the king. White Poria cocos strengthen the spleen and seep, and the source of phlegm is the minister's medicine. Ginger reduces the reverse and transforms the drink, making the poison of Banxia; ebony converts lung qi, is associated with Banxia and orange red, and there is a harvest in the dispersion, so that it can remove phlegm without hurting it, and is used as an adjuvant. All medicines are used in combination to play together to dry dampness and reduce phlegm, regulate qi and Zhonggong.

If you want to use Erxian Yimu ointment, you need to pay attention to everything. This ointment is a good medicine, so you should be cautious when using it.
First syndrome differentiation. This ointment has the effect of warming the kidney and warming the palace, promoting blood circulation and regulating menstruation, and is suitable for kidney-yang deficiency and blood stasis blockade. If the symptoms do not match, misuse it may cause other changes. For example, those with yin deficiency and internal heat often feel hot flashes and night sweats, dry mouth and dry throat. If you use this ointment, the warmth may cause internal heat to be even worse, and it will add discomfort.
Next inspection taboo. Pregnant women should never use it, because of its ability to promote blood circulation, it is easy to move fetal qi and endanger fet People who are allergic to this product should also avoid using it to prevent allergic diseases, such as rash, itching, and even shortness of breath.
Review the usage again. Be sure to use it according to the doctor's instructions or instructions. Usually taken orally, but the dose needs to be precise and cannot be increased or decreased by yourself. Overdose may cause adverse reactions, such as excessive menstrual flow, abdominal pain, etc. And during the ointment period, the diet should be light, and avoid spicy, cold, and greasy things. Spicy is easy to help heat, cold and yang damage the blood, and greasy is easy to produce phlegm and dampness, which can affect the efficacy of the medicine.
Also pay attention to the reaction of taking medicine. If symptoms do not subside after taking the medicine, or new diseases appear, such as dizziness, nausea, etc., stop taking the medicine immediately and seek medical treatment.
In addition, the preservation of the medicine is also critical. It should be placed in a cool and dry place to prevent its deterioration. If the paste has peculiar smell, discoloration, mildew, etc., it must not be reused. In this way, the purpose of safe and effective medication can be achieved.
