Dear Keith and All Unlike some other e-mails I'll descibe exactly what I have done.
500cc virgin vegetable oil (non-specific type) Heated to 35'C 80cc 99.5% Methanol added Stirred for 5 minutes Add 0.5cc (10 drops) of 97% H2SO4 Stir at 35'C for 1 hour - 600 rpm Stir without heat for 1 hr - 600 rpm Settle for 8 hrs [ At all time the vessel has been covered with tightly fitting cling film with only a very small hole for the thermo-couple to go in (maybe 1.5 to 2mm diameter). Methanol loss is negligable. ] No glycerine at all. The product has not settled but is still liquid. This is virgin oil never used fresh from the super market ASDA here, now owned by WoolMart. This morning - heated the oil to 55'C. Will add 3.1g NaOH plus 120cc of Methanol. If this turns to jelly then I will repeat again and see what happens. The single stage process works a treat every time, producing good clean ME. Keith, so the extra NaOH on top of that required to drive the reaction neutralises the FFA's (in used oil) and extracts them as soap in the final wash?
