INTRODUCTION

A colorless crystalline solid. Much denser than water and insoluble in water but soluble in chloroform and ethanol. Toxic by ingestion. Vapors are narcotic in high concentration. It is commonly employed as an electron acceptor in organic synthesis reactions. Carbon tetrabromide is also an efficient catalyst for regioselective ring opening of epoxides with alcohols.

Manufacture

It is made via bromination of methane using HBr or Br2. It can be also prepared by more economical reaction of tetrachloromethane with aluminium bromide at 100 °C.

Applications

CBr4 is used in a variety of industries

It is used as a solvent for greases, waxes, and oils
In plastic and rubber industry for blowing and vulcanization
As a sedative for polymerization
As an intermediate in manufacturing of Perbromoethylene, Tribromobutylene oxide & agrochemicals
Due to its non-flammability, it is used as an ingredient in fire-resistant chemicals
It is used for separating minerals because of its high density
In combination with triphenylphosphine, CBr4 is used in the Appel reaction, which converts alcohols to alkyl bromides
As a transfer agent for the copolymerization of methyl methacrylate and p-divinylbenzene to form soluble crosslinked polymers
As a catalyst for the aerobic photooxidative synthesis of aromatic esters from benzyl alcohols under metal-free conditions
Bromination of adamantane and its derivatives in the presence of iron compounds as catalyst
