Abstract:
In this study Neem oil was extracted using normal hexane and giving high yield
(44.37), then physico-chemical properties were determined. Due to high free fatty
acid content of Neem oil (6.6), acid pretreatment process was carried out using
methanol in the presense of 2% w/w H2SO4 as an acid catalyst at 60ºC. Then the
resulting treated oil with low free fatty acid content (1.8) undergo alkaline
tarnsesterification to produce biodiesel.
