Abstract
Carboxylic acids are known to exist prominently as dimers. Mixed dimers between different carboxylic acids are known in the gas and liquid phases, but generally revert to separate homodimers upon solidification. Following a chance discovery of an apparent stable mixed carboxylic acids dimer between acetic and phenylacetic acids, a series of substituted phenylacetic acids were prepared in high purities and converted to mixed dimers with acetic acid for study. Some, but not all substituted acids studied, appeared to form stable mixed dimers, based upon melting point and infrared analysis. Infrared analysis of the mixed dimers showed slight but significant differences from their parent acids, interpreted as hydrogen bonding between the acetic acid carbonyl and phenylacetic hydroxyl hydrogen. The physical data strongly suggest that these stable dimers observed are indeed pure molecule compounds. Attempts to generate single crystals by recrystallization for proof of structure by X-ray diffraction analysis resulted in regeneration of homo dimers.
