On the Bis-type Vitamin B_1 Derivatives, Cyclobismethylenethiamine : (III) ALKALI DECOMPOSITION

Abstract

Alkali decomposition of CBMT, was investigated. CBMT was readily decomposed to B_1 and formaldehyde by the treatment with an alkaline solution at pH≩12. The formation ratio of B_1 and formaldehyde was found to be one to one by quantitative analysis. The mechanism of alkali decomposition of CBMT was suggested by polarographic behaviours.
