There is a possibility that aliphatic ketones are contained in waste from chemical laboratories, painting factories and so on. Therefore, the polluted water must be treated in order to remove them. In this report each 5 mM ketone in the 0.05 M phosph

It's reported that the trihalomethane was produced from the 1,3-diketone structural compounds such as acetylacetone by chlorination for water supply, and the water treatment methods should be necessary to prevent their production. In this report, eac

The structures of YM-51084 and YM-51085, new protease inhibitors produced by Streptomyces sp. Q21705, were determined by 1H- and 13C-NMR and mass spectrometry. Both were characterized by the basic structures of an acyl-tripeptide. YM-51084 was elucid

In the previous paper, we described that acetic acid and caproic acid contained in water were decomposed very slowly by treatment of ozone alone, but they were decomposed very rapidly by simultaneous treatment of ozone and UV irradiation. In this rep
