초록

韓國産土炭의 흄산의$性狀^{1,2}$과 그 應用(田畓用土壤改良劑 및 溶性燐質肥料製$造^3$ 아조染料의 製$造^4$에 關해서 報告한 바와 같이 8個의 페놀성 -OH기를 가진 흄산의 構造로 보아서 황化染料의 製造原料가 될수 있을 것으로 보고 그製造條件, 染色物의 堅窄度, 製造된 황化染料의 構造를 考察해서 遊休資源인 土炭에 對한 하나의 活用策을 講究하였다.

Sulfur-dyes were manufactured from humic acid, $Na_2S_{2~3}$ and other additives at $200{\sim}250^{\circ}C$ for 3∼20 hrs. Sulfur-dyes from humic acid were fundamentally brown colors and could be changed from yellowish to grayish brown according to the additives. The colorfastness to rubbing and laundering were excellent but to weather was fair. Characteristic bonds of sulfur-dyes such as -C-S-C, -C-SO-C-. -C-$SO_2$-C-, and -C-O-$SO_2$-O-C- were confirmed but thiazole bond and thiazine ring were not done by IR-spectroscopy.
