Acetylene: First, monobromoethane and sodium hydroxide alcohol solution are eliminated to generate ethylene, and then the addition reaction of ethylene and bromine in carbon tetrachloride solution is used to generate 1,2-dibromoethane. , and then eliminate it with the alcohol solution of sodium hydroxide to generate acetylene
Ethylene glycol: First, monobromoethane and the alcohol solution of sodium hydroxide are eliminated to generate ethylene, and then use the tetrachlorination of ethylene and bromine The carbon solution undergoes an addition reaction to generate 1,2-dibromoethane, which is then hydrolyzed with an aqueous solution of sodium hydroxide to generate ethylene glycol
