IN289111: Undecenoic acid dimer esters as bio-lubricant base oils and process for the preparation thereof

Polymerization reaction of 10-Undecenoic Acid (UDA) was carried out with Montmorillonite K10 clay. The polymerized product after subsequent purification and distillation was found to be a mixture of monomr, dimer, trimer and higher polymers. The dimer fraction was isolated by distillation under reduced pressure and analyzed by physico-chemical methods. The dimer fraction was converted to various esters like methyl, propyl, butyl, 2- ethyl hexyl and evaluated for physico-chemical properties like acid value, viscosity, viscosity index and pour point and the esters are found to be potential bio-lubricant base oils with good low temperature properties.
