The negative ion mass spectrum of an aqueous solution of completely neutralized monochloroacetic acid (MCAA) was measured by a mass-spectrometric method of electrolyte solution electrospray in a vacuum. It was found that the negative ions of the MCAA acid residue, which were formed on the dissociation of MCAA molecules in water, decomposed under the electrospray. The efficiency of disintegration depends on the isotope of chlorine in the MCAA molecule.
