Glycidol → Dodecyl diglyceryl phosphate

Participants

Reaction Steps

While keeping the reaction system at 60° C., 150 g of glycidol (oxirane value=683.7) was gradually added, followed by their reaction at 70° C. for 2 hours. The acid value of the reaction system was AV1=4.4, AV2=6.0, revealing that the reaction system contained about 4.5 mole % of unreacted monododecyl phosphate and about 8.1 mole % of the corresponding phosphoric diester, i.e., dodecyl glyceryl phosphate and about 87.4 mole % of the corresponding phosphoric triester, i.e., dodecyl diglyceryl phosphate were formed.
