Preparation of medicinal carbon from coal

Yakuzaigaku 45(2): 103-110
Preparation of medicinal carbon from coal
Medicinal carbons were prepared from two kinds of coal (Japan-Taiheyo and Indonesia-Bidoli) by means of the fluidized bed activation method. The crushed species, with particle sizes ranging from 0.5 to 1.0 mm were treated with 98% sulfuric acid at C for 3 to 5 hr, then activated at C under a saturated steam atmosphere, and finally refined by washing with 1.0 to 4.0 N hydrochloric acid or caustic soda. As a result, it was found that carbon from the Bidoli refined with 2.0 N or above hydrochloric acid or with 1.0 N or above caustic soda solution as well as carbon from the Taiheiyo washed with 2.0 N or above caustic soda solution has favorable quality to conform to the standard of pharmacopoeia of Japan.
