Title: David Robert Adams: Innovator in Lubricating Compositions

Introduction

David Robert Adams is a notable inventor based in Oxfordshire, GB. He has made significant contributions to the field of chemical engineering, particularly in the development of lubricating compositions. With a total of 8 patents to his name, Adams has demonstrated a commitment to innovation and excellence in his work.

Latest Patents

Adams' latest patents include groundbreaking processes and compositions. One of his notable inventions is the preparation of sulfurized phenol additives intermediates and compositions. This process involves the reaction of olefins or acetylenic compounds with sulfurized intermediates to produce nitrile seal compatible additives. The resulting low chlorine additives are achieved through the reaction of olefin or acetylenic compounds with sulfurized compounds, such as sulfurized phenols. Additionally, he has developed a process for producing low chlorine intermediates.

Another significant invention by Adams is related to multigrade lubricating compositions that contain no viscosity modifier. This invention focuses on shear stable multigrade oils for crankcase lubrication of gasoline and diesel engines. These oils are substantially free of viscosity modifier additives and include a detergent inhibitor package of lubricating oil additives. The package features an ashless dispersant comprising an oil-soluble polymeric hydrocarbon backbone derived from an ethylene alpha-olefin copolymer or alpha-olefin homo- or copolymer. Such multigrade crankcase oils without viscosity modifiers are more economical and may provide better diesel performance and seal compatibility. They are also substantially shear stable, making them suitable for turbocharged and racing engines, with reduced mechanical breakdown of the oil.
