Lubricant Basestocks Group

Breakdown of Ester Basestock Oils Basestock breakdown in polyol ester lubricants is observed in two IR areas. Area I around 3535 cm indicates that the breakdown products are mostly composed of weakly hydrogen-bonded alcohol or acid groups. Base stock degradation is measured over the range 3595-3500 cm A single baseline point for this measurement is taken at 3595 cm to eliminate any interference from water contamination because as water contamination increases, the baseline shifts accordingly.
