Iarrtas

N - (2-Ethoxyphenyl) - N '- (4-ethylphenyl) - tha ethene diamine na stuth pòlach le sùbailteachd ìosal agus deagh sheasmhachd teirmeach. Cha dèan e dath air nuair a bhios e a’ conaltradh ri ianan meatailt agus tha e gu sònraichte èifeachdach airson solas ultraviolet tonn-ghoirid. Mar sin, bidh e gu tric air a chleachdadh mar àidseant whitening agus stàball airson siostaman ciùraidh UV.
