1,11-Dibromoundecane,Undecamethylene dibromide - Introduction
1,11-dibromoundecane, also known as bromundecane or 1-bromoundecane, is an organic compound. Its molecular formula is C11H23Br, and its structure has two bromine atoms replacing the carbon atoms of undecane.
1,11-dibromondecane is a colorless to pale yellow liquid with a special smell at room temperature. It has high density, poor solubility, and can be miscible with most organic solvents. This compound has a boiling point of 297-301 ° C. And a melting point of -10 ° C.
1,11-dibromondecane is mainly used in organic synthesis reactions as a raw material for hydrocarbon bromination reagents. It can be used in the synthesis of other organic compounds, such as aliphatic hydrocarbons, alcohols, carboxylic acids and ethers. In addition, it can also be used as a synthetic intermediate for surfactants and dyes.
The method for preparing 1,11-dibromondecane is usually to react 1-undecane with bromine, and the reaction temperature is 50-100°C. First, 1-undecane is reacted with bromine under an inert atmosphere, followed by preparation purification and refinement.
When using 1,11-dibromondecane, pay attention to the following safety information: It is a toxic compound that may cause irritation and corrosion to the human respiratory tract, eyes and skin. Therefore, wear appropriate protective equipment such as safety glasses, gloves and protective clothing during operation. In addition, it should be used in a well-ventilated place and avoid contact with strong oxidants and flammable materials to avoid accidents and fires. In case of inadvertent exposure, immediately flush the affected area with plenty of water and seek medical help.
