Summary

Fatty acids with carbon chain lengths 8 and 18 were synthesized and used as lubricants in an alumina extrusion batch. These were also combined with alumina, washed and the supernatant tested for UV absorbance. Fatty acid adsorption to A16 alumina as a function of hydrocarbon dosage was examined using UV/visible spectrophotometry. Chain length was shown to effect total adsorption. Extrusion behavior was examined using capillary rheometry and was shown to vary with hydrocarbon chain length.
