In the preparation of some special coatings or plastics, the properties of 1-bromotetradecane are used to optimize material properties to meet the needs of different application scenarios.
What are the physical properties of Bromotetradecane?
1-Bromotetradecane is also an organic compound. It has specific physical properties, related to color, state, taste, melting boiling point, density, solubility, etc.
First talk about its color state. Under normal temperature and pressure, 1-bromotetradecane is a colorless to light yellow oily liquid. Smell it, it has a slightly special smell, but this smell is not pungent and intolerable, only its inherent smell.
As for the melting point, the melting point is about 5 ° C, and the boiling point is 195-197 ° C (1.33kPa). The melting point is not high, so it is liquid at room temperature; the boiling point is fixed at a specific pressure, which is an important characteristic of its heating change.
In terms of density, it is about 0.999g/cm ³, which is heavier than water. If mixed with water, it will sink underwater.
Solubility is also a key physical property. 1-Bromotetradecane is insoluble in water because it is an organohalogenated hydrocarbon, and the force between water molecules is difficult to compete with the hydrogen bond between water molecules, so it is insoluble. However, it is soluble in many organic solvents, such as ethanol, ether, acetone, etc. Due to the principle of "similar miscibility", organic solvents are mostly non-polar or weakly polar. They are similar in structure to 1-Bromotetradecane, and the intermolecular force is suitable, so they are miscible.
In addition, the vapor pressure and refractive index of 1-bromotetradecane are also composed of its physical properties. Its vapor pressure will increase with the increase of temperature, and the refractive index is about 1.4535 (20 ° C). This parameter is of great significance for the identification and analysis of this substance.
What is the chemistry of Bromotetradecane?
1-Bromotetradecane is also an organic compound. Its physical and chemical properties are unique, and it has a wide range of uses in the field of organic synthesis.
Let's talk about its physical properties first. 1-Bromotetradecane is a colorless to light yellow liquid at room temperature, and it looks clear and transparent. This substance has a special odor, although not very strong, it is also one of its characteristics. Its density is greater than that of water, so when placed in water, it must sink to the bottom. And it is difficult to dissolve in water, but it can be miscible with many organic solvents such as ethanol, ether, chloroform, etc., just like the water of fish, the two are inseparable.
As for chemical properties, bromine atoms in 1-Bromotetradecane are active and easily participate in various chemical reactions. Take the nucleophilic substitution reaction as an example, this is a common type of reaction. Bromine atoms are like a smart dancer and are easily replaced by nucleophiles. If an aqueous solution of sodium hydroxide is reacted with it, the bromine atoms will be replaced by hydroxyl groups to form tetradecyl alcohols. During this reaction, the nucleophilic reagent hydroxyl groups successfully extrude the bromine atoms by virtue of their affinity for carbon atoms to complete the substitution process.
Another example is the reaction with sodium cyanide, where the cyanyl group replaces the bromine atoms to form tetradecanonitrile. This reaction is an important means to increase the carbon chain in organic synthesis. Fourteen nitriles can be further converted into various organic compounds. For example, tetradecanoic acids can be formed through hydrolysis reactions, which are like building a building of organic compounds and progressing layer by
1-bromotetradecane can also be eliminated. Under the action of strong bases such as sodium ethanol, the bromine atom and the hydrogen atom on the adjacent carbon atom will be removed in the form of hydrogen bromide, and then tetradecene will be formed. This elimination reaction is an effective way to prepare olefins, and tetradecene is also an important intermediate in organic synthesis. It can participate in many addition reactions to expand the structure and function of organic compounds.
In conclusion, 1-bromotetradecane plays an important role in the stage of organic synthesis due to its unique physical and chemical properties, providing a key raw material and reaction basis for the preparation of many organic compounds.
What is the production method of Bromotetradecane?
1-Bromotetradecane is also an organic compound. There are two common methods for its preparation.
First, tetradecyl alcohol and hydrobromic acid are used as raw materials. This is the classic method. Prepare an appropriate amount of tetradecyl alcohol, place it in the reaction kettle, and add hydrobromic acid, and mix the two in a suitable ratio. To promote its reaction, a catalyst such as sulfuric acid is often required. Sulfuric acid can increase the reaction rate, so it should be used with caution to prevent side reactions. Heating the temperature in the kettle to an appropriate value, about 80-100 ° C, and the reaction lasts for several hours. During the reaction, closely observe its changes, and when the reaction is completed, separate the products by distillation. The unreacted raw materials and light components are first distilled under atmospheric pressure, and then distilled under reduced pressure to obtain pure 1-bromotetradecane.
Second, it is prepared by reacting tetradecane and bromine under the action of light or an initiator. Take tetradecane into the reaction vessel, pass bromine, light or add an initiator, such as benzoyl peroxide. Light or initiator can cause bromine molecules to homogenize into bromine radicals, which can then react with tetradecane to generate 1-bromotetradecane and hydrogen bromide. The reaction temperature should be controlled at room temperature to 50 ° C. After the reaction, the product is washed with alkali solution. Except for the unreacted bromine and hydrogen bromide, it is washed with water, dried, and then purified by distillation to obtain 1-bromotetradecane.
These two methods have their own advantages and disadvantages. The former has higher yield and good product purity. However, sulfuric acid is corrosive, and the post-treatment is slightly more complex. The latter raw materials are easily available, the reaction conditions are mild, but there are many side reactions, and separation and purification are slightly difficult. In actual preparation, when depending on the specific situation, such as raw material availability, cost, requirements for product purity, etc., choose the appropriate method.
