3,5-Dimethyl-2-pentyne is an organic compound with unique physical properties. Although this specific compound is not directly mentioned in Tiangong Kaiwu, its physical properties can be deduced from the ancient people's cognition and expression of the properties of various substances as follows:
Looking at its shape, under normal circumstances, 3,5-dimethyl-2-pentyne is mostly in a liquid state. Due to the molecular structure and relative molecular mass of the compound, the intermolecular force is within a specific range, which is not enough to make it solidify into a solid state at room temperature and pressure, nor can it escape into a gaseous state.
Smell its smell, or have a special pungent smell. Many organic alkynes have this characteristic. The chemical structure of 3,5-dimethyl-2-pentyne contains carbon-carbon triple bonds. This unsaturated structure may cause it to produce a specific odor, which is stimulating to the sense of smell.
Measuring its density, 3,5-dimethyl-2-pentyne has a smaller density than water. Because organic compounds are mostly composed of relatively light elements such as carbon and hydrogen, their molecular accumulation methods are different from those of water, resulting in a lower overall density than water. If mixed with water, it will float on the water surface.
In terms of its solubility, 3,5-dimethyl-2-pentyne is insoluble in water. Water is a polar molecule, while the compound is non-polar or weakly polar. According to the principle of "similarity and miscibility", the polarity difference is large, so the two are insoluble. However, it is soluble in some organic solvents, such as ether, benzene, etc. Because these organic solvents are close to the polarity of 3,5-dimethyl-2-pentyne, the intermolecular force can promote them to mix and dissolve with each other.
Looking at its melting boiling point, due to the existence of van der Waals force between molecules and the existence of carbon-carbon tribonds, the intermolecular force is different from that of ordinary alkanes, so the melting boiling point of 3,5-dimethyl-2-pentyne has a certain range. In general, its boiling point will be higher than that of alkanes with similar molecular mass, due to the enhancement of intermolecular forces due to carbon-carbon triple bonds; the melting point is affected by factors such as molecular symmetry. Although there are methyl side chains in the structure that affect the symmetry, there is still a relatively fixed melting point range as a whole, and the specific value is determined according to accurate experiments.

3,5-Dimethyl-2-pentenonitrile is one of the organic compounds. Its chemical properties are quite interesting, let me come to you.
In terms of its unsaturation, the carbon-containing carbon double bond is a typical characteristic of alkenes. Just like the warrior holding the sword, the carbon-carbon double bond endows this compound with active reactivity. Addition reactions can occur, such as addition with hydrogen, under suitable catalysts and conditions, the double bond absorbs hydrogen atoms, turns into saturated carbon-carbon single bonds, and converts them into corresponding alkane derivatives. This process is like a warrior unloading a sword and returning to the field, tending to peace. It can also be added with halogens, hydrogen halides, etc. The molecules of halogens or hydrogen halides adhere to the two ends of the double bond, like birds falling on the branches, to form halogenated hydrocarbon derivatives.
Nitrile group (-CN) is also a key functional group. Nitrile groups have unique reactivity and can be hydrolyzed. Under the catalysis of acids or bases, they are gradually converted into carboxyl groups (-COOH), just like the metamorphosis of chrysalis and butterflies. When alkali catalyzes hydrolysis, carboxylic salts are formed first, and then acidified to obtain carboxylic acids; when acid catalyzes hydrolysis, carboxylic acids and ammonium salts are directly formed. Nitrile groups can also be reduced and treated with appropriate reducing agents, which can be converted into amine groups (-NH ²), just like after cultivation, functional groups are
In addition, this compound also has certain alkane properties due to the presence of methyl and other alkyl groups. However, due to the existence of double bonds and nitrile groups, its chemical properties are more active and unique. In the field of organic synthesis, 3,5-dimethyl-2-pentenonitrile is often an important raw material. With its active reaction check point, chemists can carefully construct more complex and delicate organic molecules, opening up new avenues for drug development, materials science and many other fields, just like building high-rise buildings with bricks and stones, and building a magnificent chemical structure based on them.

There are various methods for the synthesis of 3,5-dimethyl-2-pentenonitrile. Common ones, one can be obtained by nucleophilic substitution reaction of suitable halogenated hydrocarbons with cyanides, and then by elimination reaction. For example, first take halogenated pentane, make it and sodium cyanide in a suitable solvent, under mild conditions, perform nucleophilic substitution to obtain pentonitrile derivatives, and then treat it with strong bases to promote the elimination of hydrogen halides, so as to form 3,5-dimethyl-2-pentenonitrile.
Furthermore, aldosterone can be used. In the presence of a basic catalyst, the corresponding aldehyde and ketone are condensed with hydroxyaldehyde to obtain an unsaturated carbonyl compound, and then the carbonyl group is converted into a nitrile group. For example, 3-methyl butyraldehyde and acetone are condensed in an alkaline environment to generate unsaturated ketones, and then the carbonyl group is converted into a nitrile group by suitable reagents, such as phosphorus oxychloride and sodium cyanide, etc., to obtain the target product.
Another method is to use alkyne as the starting material. Select a suitable alkyne, introduce a methyl group through an addition reaction, and then partially reduce it, and then introduce a cyano group. For example, the addition of acetylene to methylmagnesium halide to obtain methyl-containing alkynes, and then a suitable reducing agent is used to partially reduce it to olefins. After halogenation, cyanidation and other steps, 3,5-dimethyl-2-pentenonitrile is finally obtained.
The process of synthesis requires attention to the control of reaction conditions, such as temperature, pH, solvent selection, etc., all of which are related to the yield and selectivity of the reaction. The purity of the raw materials and the cleanliness of the reaction equipment also have a great impact on the synthesis. Each method has its own advantages and disadvantages, and it should be used according to the actual needs, such as the availability of raw materials, cost, yield and product purity requirements.

There are currently 3,5-dimethyl-2-dimethyl-dimethyl-2-diethylnaphthalene in the market price range. I have carefully reviewed various market conditions and related books. The price of these organic compounds often varies depending on purity, supply and demand.
If its purity is normal and only used for general purposes, the price in the market is about tens to one or two hundred dollars per hundred grams. However, if its purity is very high and reaches the purity required for scientific research, the price will rise sharply. For high purity, the price per hundred grams may be hundreds of dollars, or even higher.
The trend of supply and demand is also a major reason. If there are many people in the market, but the supply is small, the price will rise; conversely, if the supply exceeds the demand, the price will fall. And in different places, the price varies due to freight, tax, etc. In prosperous cities, due to the convenience of transactions and the concentration of demand, the price may be relatively stable; in remote places, or due to the difficulty of transportation, the price may be slightly higher. Therefore, in order to know the exact price, it is necessary to study the local situation at that time.
