N,N'-Ethylenebis(stearamide) CAS 110-30-5
Ethylene distearamide foda ne mai launin fari zuwa rawaya mai haske ko kuma abu mai siffar granular. Yawan da ke tsakaninsa shine 0.98 (25℃), kuma wurin narkewa shine 130 ~ 145℃. Wurin walƙiya shine kimanin 285℃. Ba ya narkewa a cikin ruwa, amma foda yana da jika a sama da 80 ° C. Yana jure wa acid, alkali da ruwa. Ba ya narkewa a cikin ethanol, acetone, carbon tetrachloride da sauran abubuwan narkewa na halitta a zafin ɗaki. Amma yana narkewa a cikin hydrocarbons masu zafi da aromatics, precipitate da gel lokacin da aka sanyaya. Ethylene bisstearamide (EBS), wanda aka fi sani da vinyl bisstearamide, yana ɗaya daga cikin samfuran bisamide na farko da aka haɓaka. Tsarin EBS ya ƙunshi ƙungiyoyin amide na polar da ƙungiyoyi biyu masu tsayi na carbon, don haka yana da halayen man shafawa mai zafi da ƙarancin zafin jiki na hana ɗanko. Bugu da ƙari, yana da kyakkyawan jituwa da resin roba kamar acrylonitrile-butadiene-styrene polymer (ABS), polyvinyl chloride, resin phenolic, polystyrene da sauransu.
