Hydroxy Fatty Acid from Camelina sativa Seed Oil for Industrial Application
Renewable bio-based feedstocks are viable alternative to crude petroleum for fuel and chemical demands. Moreover, mineral oil-based lubricants used in industries and transport sector are associated with environmental concerns. Camelina sativa is an oilseed crop, and the oil may be a potential feedstock for fuel and lubricant base stocks. The present study revealed that the Camelina oil contains 82.3% of unsaturated fatty acids (monounsaturated fatty acid 33.6% and polyunsaturated fatty acid 48.7%). The physicochemical properties of Camelina oil reveal the presence of long chain fatty acid and high unsaturation. The oil may be chemically modified for lubricant applications and eco-friendly. The article describes the modification of Camelina oil to hydroxy fatty acid by the process of splitting, separation of saturated fatty acid so that the unsaturated fatty acid having iodine value 160gI2/100 g is further epoxidized to obtain hydroxy fatty acids. The hydroxy functionality introduced into the Camelina fatty acid serves as a potential renewable material for synthesis of bio-lubricant base stocks.
