  Fatty acid-derived ionic liquids as renewable lubricant additives: Effect of chain length and unsaturation

  摘要：

  Fatty acid-derived ionic liquids (FAILs) are synthesized and then demonstrated as the environmentally-friendly additive to mineral lube base oil for enhancement of lubrication properties. Unlike most of the conventional ionic liquids, FAILS exhibited good miscibility with non-polar mineral lube base oil. The quaternary structure of tetrabutylammonium (TBA) cation, diffused positive charge on the cationic center due to +I effect of alkyl chains, and the alkyl chain of fatty acid anion collectively facilitates the miscibility of FAILS in the mineral lube base oil. Experimental results revealed that 1% FAILs could significantly reduce the friction (16-27%) and wear (9-15%) of lube base oil. The viscosity of these ionic liquids is found to be governed by alkyl chain-length and unsaturation of fatty acid anions, and it exhibited a linear correlation with the coefficient of friction. The elemental mapping of worn surfaces on aluminium disc suggested the formation of ionic liquids-derived tribochemical film, which is accounted for protection of tribo-interfaces to reduce the wear and friction. The FAILs being halogen-free, environment-friendly, having an excellent affinity towards engineering surfaces, and good miscibility with non-polar hydrocarbon lubricants, promised the immense potential for tribological applications.

  Undesirable deposition of polyoxymethylene onto the inner wall of a polymerization vessel and onto a stirrer, which deposition is observed in the slurry polymerization of formaldehyde carried out in an inert organic liquid medium in the presence of a polymerization catalyst, can be minimized by carrying out the slurry polymerization in the presence of at least one polyvalent metal salt selected from polyvalent metal salts of alkylsalicylic acids and polyvalent metal salts of dialkyl esters of sulfosuccinic acid. Optionally, a polyethylene glycol monoether may be used in addition to the polyvalent metal salt.
