Package
The package of all our chemical products reaching up to the industry standard, we usually use kraft drums or woven bags for our powder state products.
Preparation:
Diphenylene oxide is recovered from a wash oil fraction of coal tar that boils between 275 °C and 290 °C. Redistillation separates diphenylene oxide from acenaphthene, which boils at a lower temperature. Crystallization of the redistilled fraction then produces technically pure diphenylene oxide
Application:
Diphenylene oxide is used as an insecticide, in the production of PVC, industrial bleaching and incineration. Diphenylene oxide can also produce veterinary nitrate(Bayer 9015), For the treatment of cattle, sheep and other liver fluke disease.Washing Oil suppliers
