PURPOSE:To obtain a lubricating oil suitable for plastic processing of metal, having excellent friction coefficient and resistance to pressure at high pressure and high-speed rotation, comprising esterified product obtained by reacting specific nitrogen-containing alcohol and specific mixture of aliphatic acid/rosins. CONSTITUTION:The aimed lubricating oil is composed of >=1 esterified compound resulted by a reaction of (A) nitrogen-containing alcohol expressed by formula I and/or formula II (X is H or CH3; n is 1-10; R is 2-6C alkyl, phenyl or cyclohexyl) and (B) a mixture of (i) >=6C aliphatic acid and (ii) rosins containing asymmetric rosin, hydrogenated rosin or polymerized rosin in weight ratio (i):(ii)=95:5-25:75. |
