Synthesis of Soy based Biodegradable Grease

Abstract

The use of biodegradable lubricants in industrial as well as automotive applications has gained significance in recent years. Owing to their superior properties and performance characteristics bio-lubricants offer an ideal alternative to conventional mineral oil based lubricants. In addition the use of bio grease negates the need for additional expenditure to ensure proper disposal of non-biodegradable grease. There has been a growing interest in the production of bio-based and biodegradable greases. Calcium sulfonate greases are some of the most versatile greases and are often used as multi-purpose greases. Some calcium sulfonate greases are classified as food grade greases. They also show potential to be used in various sectors like agriculture, forestry, railways including other areas of application. This paper presents the formulation process and standardized test results of calcium sulfonate based bio-grease along with an overview of the various manufacturing processes that can be employed in the synthesis of grease.
