Determination of peroxide in tetrahydrofuran
Tetrahydrofuran and ether are easy to produce peroxide when stored for a long time. Be careful when using. Be sure to detect the peroxide content in the solution first. If more than 0.05% peroxide is present, the peroxide must be removed before distillation. If the peroxide content is 1% or higher, it must be treated by incineration.
