Abstract
Recovered 25 per cent glycerine solution from the bard resin manufacturing processes is partially purified and concentrated to an acceptable color for reuse in resin production. The purification initially starts with the solution adjustment to pH?, the disproportionation product of resin acids are precipitated and removed. The glycerine is then passed through a cation ion-exchange resin column removing aldehydic impurities. The effluent is then concentrated and reacted with an equivalent amount of phthalic anhydrite forming a glycerol phthalate ester to ascertain a color which is equivalent to that of the finished resin that is commercially acceptable.
