Bioethanol Quality control of bio diesel fuel (BDF) on acid number is important since the number increases when the fuel itself deteriorates or BDF in production in line is not conforming.
The acid number of BDF is measured according to JIS, ASTM or ISO standards by potentiometric titration with 0.lmol/L potassium hydroxide 2-propanol solution until the endpoint is found on titration curve.
The acid number of bio diesel fuel is calculated from the titration volume of potassium hydroxide 2-propanol solution consumed in reaching the endpoint.
