SUMMARY Methyl alcohol, ethyl alcohol, chloroform, diethyl ether, petroleum ether, cyclohexane, and carbon tetrachloride were tested for reactivity with thiobarbituric acid. Pigments with absorption maxima at 450 and 532 mμ were readily formed from petroleum ether and diethyl ether; methyl alcohol, ethyl alcohol, chloroform, and hexane reacted, but to a lesser extent; carbon tetrachloride was unreactive. The production of these malonaldehyde‐like compounds, presumably from contaminants in the solvents, was increased by heating.
