Alcohol bottom is a by-product, or distillation residue, from the production of C8-C18 fatty alcohols while ester bottom is a by-product or distillation residue, from the production of C8- C18 methyl esters. They can be used to adulterate crude palm kernel oil (CPKO), one of the feedstocks used for the production of oleochemicals. MPOB has developed a rapid technique to detect adulteration of CPKO by alcohol bottom and ester bottom.
