Triglycerides catalytic transesterification by e.g. sodium, potassium, barium, and strontium (Na,K,Ba,Sr) glycerylates comprises catalyst neutralization with reflux reaction of triglyceride and alcohol

摘要

The triglycerides catalytic transesterification by e.g. Na, K, Ba,r glycerylates has catalyst neutralization by glacial acetic acid and carbon dioxide. The e.g. vegetabel triglyceride yields raw glycerine of high richness, free of metal salts, through reflux reaction of a mixture of 1 mole of triglyceride, 3-8 moles of alcohol and e.g. synthetic zeolite at maximum 400 degrees C.
