Allen et al. (1945)patented a continuous process whereby 224 part/min of refined coconut oil and 96 part/min of ethanol containing 0.75% of NaOH catalyst were homogenized and then pumped through a reaction coil for about 10 min at 100°C. The mixture passed through a preheater to bring the temperature to 110°C followed by loading into a packed column for separation of the ethanol vapour. The glycerol was separated out in a lower layer. The ester layer was washed and dried under vacuum.
