Further Studies of the Interaction of Chlorine and Organic Molecules in Water.

摘要

The existence of nucleic acids and their derivatives in water has been reported. Unexpectedly large amounts of chlorine are incorporated into the nucleic acids,both RNA and DNA. Chlorine attacks the pyrimidine derivatives of nucleic acid first,then attacks the purine derivatives of nucleic acid destructively to form small fragments. 5-Chlorocytosine and 5-chlorouracil were isolated from the chlorinated RNA. 5-Chlorocytosine but no chlorinated thymine derivatives were isolated from the chlorinated DNA. Lignins were chlorinated with chlorine in water to 17% chlorine content. Vanillin is susceptible to chlorination but caffeine is not.
