Yield:-
Reaction Conditions:
with bromine at 21; for 0.0075 h;Product distribution / selectivity;
Steps:
1
A stream of ethane with a flow rate of 5 standard ml/min is passed through a bromine bubbler held at 21° C. The resulting mixture of ethane and bromine having a molar ratio of 3.6:1 (ethane:bromine) is passed through a glass reactor having a 3.6 mm inside diameter. The glass reactor is packed with borosilicate beads and the average residence time in the reactor is 27 s. 100% of the bromine is converted. 24% of the ethane is converted with selectivities of 86% to ethyl bromide, 12% to 1,2-dibromoethane, 1% to 1,1-dibromoethane, and <1% of 1,1,2-tribromoethane.
