Isi ụdị sọlfọ dị iche iche bụ sọlfọ ojii (CI sulfur black 1). A na-akwado ya site na hydrolyzing 2, 4-dinitrochlorobenzene na sodium hydroxide ngwọta n'ime sodium dinitrophenol ngwọta na nso esi mmiri, wee kpo oku na esi na sodium polysulfide ngwọta na ụfọdụ molekụla ratio, na mbenata na sulfurizing mmeghachi omume n'okpuru nrụgide ma ọ bụ enweghị nrụgide. Mgbe emechara mmeghachi omume sulfurization, a na-akpọnwụ ya ozugbo na igwe nkụ iji nweta agba mbụ. Mgbe ahụ, a na-agwakọta ya ka ọ bụrụ ihe eji esiji ere ahịa.
