Ethanol → Bisphenol A

Participants

Reaction Steps

A 0.05 mole sample of bis-phenol A was dissolved in an ethanol-water solution containing 95% ethanol. This solution then was added dropwise to a 0.05 mole fraction of N,N-dimethyl-1,3-propanediamine sample dispersed in 50 milliliters of an ethanol-water solution containing 95% ethanol. The addition of the bis-phenol A fraction to the propanediamine sample was at room temperature (70° F.) over a 15 minute period. There was a slight exotherm during the addition. After all the bis-phenol A was added, the solution was stirred for an hour and then the solvent flashed using a rotary vacuum distillation apparatus. The residual solids were transferred to a vacuum oven to dry, and a N,N-dimethylpropanediamine salt of bis-phenol A was obtained.
