A method for qualitative and quantitative analysis by GC/MS and GC of ethers and related olefines in light gasoline from catalytic cracking before and after etherification has been presented. By means of the analysis of the reactive olefines and the ethers produced it is concluded that six kinds of olefines had taken part in the etherification process, they were, 2 methyl propene 1,2 methyl butene 2,2 methyl butene 1,2 methyl pentene 1,2 ethyl butene 1, and 2 methyl pentene 2,and the four ethers produced were 2 methoxy 2 methyl propane, 2 methoxy 2 methyl butane, 2 methoxy 2 methyl pentane and 3 methoxy 3 methyl pentane. These ethers are all contributing to enhance the octane number.
