<p>A purification process for purifying a solvent, especially methanol comprises introducing feedstock solvent into a boiling vessel. The feedstock is refluxed for a period of at least 5 minutes, distilling the methanol and delivering the purified solvent into a first purified solvent receiver. Further feedstock is drip fed into the boiling vessel. The delivery of purified solvent is directed to a second receiver while the purified solvent in the first receiver is bottled. Sodium borohydride is added to the boiling vessel in an amount of approximately 0.025% by weight of the methanol.</p> |
