    AKWỤKWỤKWỌ CHINEKE

    N, N-Dimethylformamide bụ mmiri mmiri na-enweghị agba ma ọ bụ ntakịrị odo na-esi ísì ụtọ nke 153ºC yana ike ikuku nke 380 Pa na 20 ° C. Ọ na-agbaze n'efu na mmiri yana soluble na alcohols, acetone na benzene. N, N-Dimethylformamide na-eji dị ka ihe mgbaze, ihe na-akpali akpali na gas absorbent. Meghachi omume ike site na iji sulfuric acid gbadoro ụkwụ, na-afụ nitric acid na ọbụna nwee ike ịgbawa. Dimethylformamide dị ọcha enweghị isi, mana ọkwa ụlọ ọrụ mmepụta ihe ma ọ bụ gbanwee Dimethylformamide nwere ísì azụ n'ihi na ọ nwere adịghị ọcha nke Dimethylamine.
