Reaction Steps

1790 g of 90% glycerine monostearate premixed with 920 g of glycerine were heated under nitrogen blanket up to 100° C. The catalyst was prepared by dispersing 8 g of Ca(OH)2 (dry) with 52 g of water and then 30 g of 25% H3PO4 premixed with 60 g of water was slowly added into it while stirring for 30 minutes. Such prepared catalyst mixture was added at 100° C. to glycerine monoglyceride. This reaction mixture was then heated up and nitrogen replaced with slow application of vacuum. At 120° C. and vacuum of 20 inches the first water started to come over. In 3 hours time 230° C. was reached at 23 inches of maximum vacuum and 160 g of water was removed. This condition was kept for another 3 hours and 310 g of total water was collected.
