The average epoxy value and the average viscosity of such diluent were 0.502×10-2eq/g and 3.2 mPa.s(25 ℃) respectively. It was an ideal diluent and could be used instead of active diluent such as butyl epihydrin etc. and non-active diluent such as dibutyl phthalate etc. in epoxy resin industry. The preparation of the epoxy diluent by fusel oil could not only settle the problem of environmental pollution caused by fusel oil drainage, but also produce economic and social benefits.
