The FATTA method
This is not for those who don't like failed batches; the proportions and process methods are still under experimentation.
THE PROCESS IS AIMED AT HIGH FFA CONTENT OILS AND ANIMAL FATS WHERE UNDER NORMAL BASE REACTION LOW YIELDS ARE ACHIEVED (<65%).>60C and cool slowly.
Filtering could be required to separate glycerol and soaps from ester.
What happens to the H2SO4, it is neutralized
2NaOH + H2SO4 ---> Na2SO4 + 2 H2O
This produces water, but no more than when neutralizing the FFA with a base.
An example of the acid reaction
2000ml Fat at 50C
400ml CH3OH (Higher volumes of Methanol were used in the original experiments)
2ml H2SO4
Reaction time (minutes) titration value (ml)
0-min 4.0
30-min 3.4
60-min 3.2
90-min 2.8
120-min 2.6
Indicated a reaction time of 2 hours was needed.
