catappa oil: Acid, peroxide, iodine and saponification values of the oil samples were determined according to the AOAC method [9].
The monitoring of the saponification value (an indicator of the content of fatty acids from oils and the solubility of their soaps) was made in order to observe the differences between sunflower oil and waste cooking oils during transesterification reaction.
Thus, taking into consideration the average saponification value of the oil sample, we found that 6-fold excess of alkali (1 mL of 10 M KOH solution/0.
Decrease in iodine value is due to the decrease in the degree of unsaturation, lowering of hydroxyl value from PEA to CDPEA is due to the decrease in the fatty acid content and decrease in the saponification value from PEA to CDPEA is attributed to the increase in the molecular weight of the polymer.
Saponification value of oil sample was determined according to the method reported by Pearson [17].
The polymer's molecular weight was 60 kDa and the saponification value was 98-99%.
Saponification value (SV), Free fatty acid (FFA), Iodine value (IV), viscosity, moisture content and specific gravity were determined.
