Make sure the oil is dry before you react.
Measure out 20 litres of methanol (20% volume/oil)
Dissolve 100 x 5g (NaOH) or 100 x 7.5g (KOH) into 16 litres of methanol add to the reaction at 55-60c
Pump/mix for 1 hour, less if you have an eductor (I also supply these) at 55-60c
Take a sample and allow to settle. Pipette 10ml of biodiesel from the top and add to 90ml methanol in the titration flask at room temperature. Add the stopper and shake, let this stand for the fallout to collect ( these stand well in a jam jar). Picture 2
Measure the unreacted oil ie if there is 3ml dropout then you have 30% unreacted oil remaining, so the next step is to calculate the amount of NaOH to convert the remaining 30 litres.
Allow the reaction to stand for 30mins, then drain the glycerol.
Dissolve 30 x 5g NaOH or 30 x 7.5g KOH into the remaining 4 litres of methanol and add to the reaction at 55-60c
Pump/mix for 30-60mins
Repeat from step 5 without draining the glycerol - you should be seeing no or little dropout.
Continue until you have a homogeneous solution within the dropout tube Picture 3
When 10ml or more of your biodiesel dissolves into the methanol without fallout –then this is a pass - It should have a yellow transparent appearance
Continue the process with your chosen method of purification
