I know this is a strange question. Does anyone know how a chemist might determine the SAP values (for NaOH) of a mystery vegetable/animal oil sample?
I found ASTM D5558 - 95(2011) Standard Test Method for Determination of the Saponification Value of Fats and Oils on the web, but they want $35 for two PDF pages. Ouch.
Some on this site use all the right words in the right order and lead me to believe they might know how SAP is determined.
Thoughts?
Okay, here is what I'm thinking. I can get oils/fats in a blend. I don't know the blend, so I can't calculate the recipe using percentages of a single blend. I want to use it to make soap but need the SAP value of that particular mix of oils/fats. Is there a spiffy junior-chemist way of figuring it out?
