A green and eco-friendly method for preparation of oleochemicals from Camelina oil was developedfor possible application for bio-lubricant basestocks, The steps involved are consisting of epoxidationof Camelina oil based fatty acid followed by further branching with wide range of alcohol such as2-propanol, n-butanol, isoamyl alcohol and 2-ethylhexanol. These products were evaluated withphysico-chemical properties such as acid value, oxirane oxygen content (OOC), hydroxyl value, lowtemperature properties, viscosity at 40 and 100 °C, viscosity index and characterized by FTIR, 1HNMR. The appearance of peak at 824 cm–1 in the FTIR spectra was due to the formation of epoxygroup and broad peak appeared at 3500-3300 cm–1 is for hydrogen bonded O-H stretching vibration ofhydroxy group. The 1H NMR spectra showed a signal at 2.9-3.2 ppm region indicated CH-protonattached to the oxygen atom of the both epoxy group for epoxidized product, peaks for newly formedsecondary alcohols emerged at 4.25-3.35 in alkoxy derivatives. The Camelina based synthetic productmay find application in biolubricants base stock.
