To prepare hexa- (triethylamino) hexane-2-enal, it can be obtained by various methods.
First, use hexadialdehyde and triethylamine as raw materials. In a suitable reaction vessel, put hexadialdehyde and triethylamine in an appropriate proportion, add an appropriate amount of catalyst, and make them condensate under a specific temperature and pressure. This reaction condition needs to be precisely regulated. If the temperature is too high or too low, and the pressure is not appropriate, it may cause changes in the reaction rate or product selectivity. If the temperature is too high, or side reactions occur, the purity of the product will be reduced; if the temperature is too low, the reaction will be slow and time-consuming.
Second, react with a suitable halogenated hexenal and triethylamine salt. The halogenated hexenal is first prepared, and then mixed with the triethylamine salt in the solvent. Under the action of the base, a nucleophilic substitution reaction occurs. It is crucial to choose a suitable solvent and base. The solvent needs to have good solubility to the reactants and does not react adversely with the reactants and products; the strength and dosage of the base will also affect the reaction process and product yield.
Third, it can be converted by alkenal derivatives. First synthesize the alkenal derivative containing a specific functional group, and then convert it into hexa- (triethylamino) hexene-2-alkenal through the functional group conversion reaction. This process may involve multi-step reactions, and each step needs to be carefully operated to ensure the purity and yield of the product.
During the preparation process, attention should be paid to the optimization of reaction conditions, such as temperature, pressure, ratio of reactants, catalyst dosage, etc., which will have a significant impact on the reaction results. And the separation and purification of the product is also critical. Commonly used methods include distillation, extraction, column chromatography, etc. According to the physical and chemical properties of the product and impurities, a suitable separation and purification method is selected to obtain high-purity hexa- (triethylamino) hexene-2-enal.

(Triethylamino) ethylene-2-acetaldehyde, that is, triethylenediamine, has the following physical properties:
This substance is a colorless to light yellow transparent liquid at room temperature, with an ammonia smell. The melting point is critical, about 158 ° C. At this temperature, the substance changes from solid to liquid. The boiling point is about 218 ° C. When this temperature is reached, the liquid substance will quickly transform into a gaseous state.
Its density is different from that of water. The relative density (water = 1) is about 1.034, which means that it is slightly heavier than water. In terms of solubility, triethylenediamine is soluble in water and can also be miscible with organic solvents such as ethanol and acetone. This property makes it an excellent solvent or medium for participating in reactions in many chemical processes.
In addition, triethylenediamine also has hygroscopicity, which makes it easy to absorb water in the air, thus affecting its purity and related properties. Because of its alkalinity, it can act as a base catalyst in some chemical reactions to promote the progress of specific reactions.
From the perspective of volatility, it has a certain degree of volatility and will slowly evaporate in the air, which requires attention during storage and use to avoid losses due to volatilization or other problems. These physical properties determine its use and application in many fields such as chemicals and materials.

(Triethylamino) vinylacetylene, also known as beta- (triethylamino) butadiyne, is a class of organic compounds. And α-ethanethiol, also known as ethanethiol, belongs to the mercaptan class of substances. The following is a detailed description of the chemical properties of the two:
###(triethylamino) vinylacetylene Chemical properties
1. ** Nucleophilic reaction **: The molecule contains an alkynyl group, which is nucleophilic and can undergo nucleophilic addition reactions with electrophilic reagents. For example, under appropriate conditions, it can undergo nucleophilic substitution with halogenated hydrocarbons at the alkynyl check point, and then grow the carbon chain to synthesize more complex organic compounds.
2. ** Addition reaction **: Due to the unsaturated carbon-carbon triple bond, an addition reaction can occur. Take the addition of hydrogen as an example, under the action of a suitable catalyst, it can be gradually hydrogenated to form olefins, and finally alkanes. Or add to halogen elementals, hydrogen halides, etc., to generate corresponding halogenated hydrocarbon derivatives.
3. ** Basic **: The triethylamino part of the molecule contains nitrogen atoms, and there are lone pairs of electrons on the nitrogen atom, so that the compound has a certain alkalinity and can react with acids to form salts.
### α - Chemical properties of ethanethiol
1. ** Acidic **: Compared with alcohols, thiols have stronger S-H bond polarity, easier to break, and release hydrogen ions, so α-ethanethiol is slightly more acidic than ethanol. It can neutralize with bases to generate corresponding salts.
2. ** Oxidation reaction **：α - ethanethiol is easily oxidized. Under mild oxidation conditions, it can be oxidized to disulfide; if a strong oxidizing agent is used, such as potassium permanganate, it will be further oxidized to sulfonic acid.
3. ** Nucleophilic reaction **: There are lone pairs of electrons on the sulfur atom, making α-ethanethiol nucleophilic, capable of nucleophilic substitution reaction with halogenated hydrocarbons and other electrophilic reagents to form new sulfur-containing organic compounds.
4. ** Special odor **：α - ethanethiol has a very strong and special odor, which is its significant physical-chemical properties. Even at very low concentrations, people can also be keenly aware, and it is often used for odorization of odorless gases such as natural gas in order to detect gas leakage in time.

In today's world, business conditions are ever-changing, and in the market, prices vary from time to time and change according to the situation. As for the price of (trienomethyl) alkyl-2-methylnaphthalene in the market, it is difficult to determine the price.
In the market, its price is often tied to the state of supply and demand. If there are many people seeking this item, but the supply is small, the price will rise; if the supply exceeds the demand, everyone will compete to sell it, and the price will naturally decline. And all kinds of materials also affect each other. Or there may be substitutes, causing their need to decrease, and the price will also decline; on the contrary, if there are many people relying on it, and there is nothing else to replace it, the price will skyrocket.
In addition, things are impermanent, natural disasters and man-made disasters, and changes in government orders can all affect prices. If there are disasters in the sky, it is difficult for them to purchase, supply or reduce, and the price will be high; if the government imposes restrictions, it will be difficult for them to enter and exit, and the cost will increase and the price will rise. Furthermore, the calculations of businesspeople and the atmosphere of the market are also related to the price. All businesspeople are optimistic about this item, and if they stock up, the price will rise; if they are all bearish and sell in a race, the price will fall. < Br >
is that in order to know the current market price of (trienomethyl) alkyl-2-methylnaphthalene, it is necessary to widely observe the market conditions, gather the number of supply and demand, and observe the political and commercial trends.
