In addition to alkyl benzenes, the composition also <br/>contains an antioxidant, an antifoaming agent, a pour point dispersant, a <br/>corrosion inhibitor and a detergent-dispersant additive, an extreme pressure <br/>additive and a lubricity additive. The present invention further provides a <br/>process comprising the following steps (I) : removing of insoluble matter from <br/>the base stock, (II) tailoring the base stock by vacuum distillation and <br/>blending, (IV) removing the oxidized matters by adsorption, (V) addition of <br/>performance additives and homogenizing the mixture.. The product of this <br/>invention has utility as an general purpose hydraulic fluid.<br/></p> |
