TRENDS IN THE PROCESS OF GREENING LUBRICANTS
Tribologia, 2020In this article, the authors have characterized the main activities that reduce the impact of lubricants on the environment. To begin with, new solutions in the area of engine oils that reduce the emission of harmful substances in exhaust gases (“Low SAPS” oils) were discussed.

Anticorrosion and lubricating properties of a fully green lubricant
Tribology International, 2019Abstract A kind of ecofriendly ricinoleic acid based ionic liquid was used as a multifunctional lubricant additive in glycerol solution. Its surface tension, anticorrosion and lubricating properties were investigated. Above the critical micelle concentration (CMC) it remarkably improves the anticorrosion and lubricating abilities of glycerol solution

Carbohydrate Polymers, 2022
Industrial lubricants are widely introduced to the mechanical systems to reduce the wear and energy losses. With the increasing demand for environmental protection, developing eco-friendly lubricants becomes more crucial. Due to their abundance, biodegradability, non-toxicity, high thermal stability and low cost, cellulose nanocrystals (CNCs) may be an

Green Ester Lubricants Based on Rapeseed Acid and their Lubricity
Advanced Materials Research, 2013Several complex esters were synthesized from phthalic anhydride, neopentyl glycol and rapeseed acid. Their rheological properties, biodegradability and tribological properties were measured. It was found that the complex esters have a wide viscosity range of 126~325mm2/s at 40°C with viscosity indices about 127~143, and solidifying points lower than-38°

Increased demand to protect the environment from mineral oil based lubricants has necessitated replacing them with products derived from natural resources. In addition to this a combination of environmental, health, and economic challenges has also renewed interest in the development and use of green lubricants over the last two decades.

Green Additives for Lubricating Oil
ACS Sustainable Chemistry & Engineering, 2013The increasing focus toward diminishing the impact on the environment has driven efforts to develop new environmentally benign lubricating oil additives. Keeping this view in mind, the present investigation comprises the syntheses of homopolymers of sunflower oil (SFO) and soybean oil (SBO) for their evaluation as lube oil additives.

Green Lubricants: Role of Additive Size
2012The depletion of the world’s crude oil reserve, increased oil prices, and the demand to protect the environment against pollution exerted by hydraulic and gear oils have brought about renewed interest in the development and use of green lubricants. In this light, many automotive and manufacturing industries are actively seeking out new green lubricants.
