1 PROCESS ECONOMICS PROGRAM STANFORD RESEARCH INSTITUTE Menlo Park. California Abstract Process Economics Program Report No. 125 SYNTHETIC LUBRICANTS This first PEP report on the subject presents technical and econanic information on three of the synthetic lubricants that show the greatest promise for growth over the next decade by displacing petroleum lubricants in automotive and industrial applications. They are: Linear Alpha Olefin Oligomers Neopolyol Esters Dibasic Acid Esters Technology and econanics are presented for making a typical product from each of the above three general types, as follows: Hydrogenated Decene-1 Oligomer Technical Pentaerythritol Esters Di-Tridecyl Adipate
2 Report No. 125 SYNTHETIC LUBRICANTS MAX SACKS May 1979 A private report by the PROCESS ECONOMICS PROGRAM Menlo Park, California 94025
3 For detailed marketing data and information, the reader is referred to one of the SRI programs specializing in marketing research. The CHEMICAL ECONOMICS HANDBOOK Program covers most major chemicals and chemical products produced in the United States and the WORLD PETROCHEMICALS Program covers major hydrocarbons and their derivatives on a worldwide basis. In addition, the SRI DIRECTORY OF CHEMICAL PRODUCERS services provide detailed lists of chemical producers by company, product, and plant for the United States and Western Europe. ii
