Ọrụ na ojiji nke diethanolamine

Diethanolamine (DEA) bụ ngwakọta organic nke nwere usoro kemịkalụ C4H11NO2. Ọ bụ mmiri viscous ma ọ bụ kristal na-enweghị ụcha nke bụ alkaline ma nwee ike ịmịnye gas dị ka carbon dioxide na hydrogen sulfide na ikuku. Diethanolamine dị ọcha bụ ihe siri ike na-acha ọcha n'ime ụlọ, mana ọ na-eme ka ọ dị nro na nke dị jụụ na-eme ka ọ na-apụta mgbe ụfọdụ dị ka mmiri mmiri na-enweghị agba na nke doro anya. Diethanolamine, dị ka amine nke abụọ na diol, nwere ọtụtụ ojiji na njikọ organic. Dị ka ogige amine ndị ọzọ, diethanolamine adịghị ike. N'afọ 2017, Healthtù Ahụ Ike Ụwa's International Agency for Research on Cancer wepụtara ndepụta ntụaka mmalite nke carcinogens, ma tinye diethanolamine na ndepụta nke ụdị 2B carcinogens. Na 2013, a na-ekewa ogige ahụ dị ka "ikekwe carcinogenic ụmụ mmadụ" site na International Agency for Research on Cancer.
