31772-06-2 - Introduction
1,18-dibromooctadecane (1,18-dibromooctadecane) is an organic compound with the chemical formula C18H36Br2. It is a colorless liquid with a strong odor. The following is a description of its nature, use, preparation and safety information:
Nature:
-1,18-dibromooctadecane is a colorless liquid that is not volatile at room temperature.
-It is insoluble in water and soluble in organic solvents such as alcohols, ethers and alkanes.
-Its density is higher, and its melting point and boiling point are also higher.
Use:
-1,18-dibromooctadecane is a reagent commonly used in organic synthesis and is widely used in organic synthesis reactions.
-It can be used as an alkylating agent to introduce alkyl chains.
-It can also be used to synthesize surfactants, flame retardants and pharmaceutical intermediates.
Method:
1,18-dibromooctadecane can be synthesized by the following steps:
1. Octadecane is reacted with Methylene bromide to generate the corresponding octadecylmethylene bromide under suitable conditions.
2. React octadecamethylene bromide with Methylene bromide again to obtain 1,18-dibromooctadecane.
Safety Information:
-1,18-dibromooctadecane is irritating and corrosive to the skin and eyes, so you need to wear protective equipment during use to avoid direct contact with the skin and eyes.
-During operation, a well-ventilated environment should be maintained to avoid inhalation of vapors or gases from the substance.
-For accidental contact or ingestion, rinse immediately with plenty of water and seek medical help if necessary.
-Due to its toxicity and corrosiveness, 1,18-dibromooctadecane needs to be stored and handled with special care and follow relevant safety procedures.
