Versuchsvorschrift

A mixture of 605 g (3.0 mol) of 1,3-dibromopropane and 250 g (1.5 mol) of triethyl phosphite was heated at an oil bath temperature of 130° C., while stirring and passing in nitrogen, for approximately 5 hours until approximately 154 g (1.5 mol) of bromoethane distilled over into a strongly ice-cooled receiver. The reaction mixture was distilled first in a bulb tube and then fractionally.
