1 10 dichlorodecane properties applications
On the properties of 1,10-dichlorodecane with
1,10-dichlorodecane, is a special organic compound. Its physical properties are unique. At room temperature, it is a colorless to light yellow oily liquid with a certain volatility, but the volatilization rate is relatively slow. Its melting point is quite low, about -9 ° C, and its boiling point is higher, reaching 280 ° C, which makes it able to maintain a liquid state in the common temperature range. And its density is slightly higher than that of water, about 1.04 g/cm ³. It is insoluble in water, but it can be miscible with many organic solvents, such as ethanol, ether, benzene, etc.
Looking at its chemical properties, 1,10-dichlorodecane has active chlorine atoms. Due to the strong electronegativity of the chlorine atom, it has the same polarity as the C-Cl bond formed by the carbon atom. This polarity makes the bond vulnerable to attack by nucleophiles, and then nucleophilic substitution reactions occur. For example, when heated with an aqueous solution of sodium hydroxide, the chlorine atom can be replaced by a hydroxyl group to form 1,10-decanediol; if reacted with an ethanol solution of sodium cyanide, the chlorine atom will be replaced by a cyano group to give 1,10-dicyanodecane, which can be converted into 1,10-decanedioic acid after hydrolysis. This diacid is widely used in the field of polymer synthesis.
As for its application, in the field of material synthesis, 1,10-dichlorodecane is an important monomer. Due to the high activity of chlorine atoms at both ends of the molecule, it can be used with compounds containing active hydrogen, such as diols and diamines, to prepare polymer materials with excellent performance through polycondensation reaction. Taking its reaction with ethylenediamine as an example, polyamide polymers can be formed. Such polymers have good mechanical properties and high strength. In the field of engineering plastics, such as the manufacture of automotive parts and mechanical components, they can be used as structural materials. With their good wear resistance, corrosion resistance and dimensional stability, they can effectively prolong the service life of components.
In organic synthetic chemistry, 1,10-dichlorodecane is a commonly used intermediate. With its active chlorine atoms, a variety of functional groups can be introduced and converted, thus building complex organic molecular structures. Organic synthetic chemists often use it as a starting material, through a series of reaction steps, to construct natural product analogs or new drug molecular skeletons with specific biological activities, providing an important material basis for the development of new drugs.
In the preparation of surfactants, 1,10-dichlorodecane also has extraordinary performance. By linking it with appropriate hydrophilic groups, a class of surfactants with unique properties can be prepared. Such surfactants can significantly reduce surface tension at the oil-water interface, so that oil droplets are uniformly dispersed in water to form a stable emulsion system. In daily chemical products, such as shampoo and body wash, it can enhance the emulsification and cleaning ability of products to oils; in industry, it is also indispensable in emulsion polymerization, mineral flotation and other processes to improve production efficiency and product quality.
1,10-dichlorodecane has shown important application value in many fields due to its unique properties, promoting the development of materials science, organic synthesis and chemical engineering and many other disciplines.
