- Abstract:
- Catalytic thermometric titrition has been developed for the determination of the acidity of oils. The amounts of oil, concentration and delivery rate of titrant, volumes and types of thermometric indicator were investigated. The results show that mixture of acetone and chloroform used as indicator exhibits strongly exothermic effects to reflect end point obviously. The method is fast, easy to use, accurate, and highly reproducible to measure lower acidity in non-coloured and coloured oils.
