Synthesis of a sulfur-containing additive to transmission lubricants based on the C20-C26 fraction of α-olefins

Hydrogen peroxide-independent production of α-alkenes by OleTJE P450 fatty acid decarboxylase

“…Thus, this P450 fatty acid decarboxylative machinery may hold great potential to be engineered into a biological α -alkene-producing system. Notably, in addition to being biofuel molecules, α -alkenes are also used broadly for making lubricants, polymers and detergents [ 17 , 23 , 24 ].…”

On the engineering of reductase-based-monooxygenase activity in CYP450 peroxygenases

“…8,9 Aliphatic aalkenes are important components that can be used to replace fossil fuels, as well as for the production of lubricants, detergents, and polymers. [10][11][12] This makes CYP450 OleT a promising biocatalyst for biofuel production and commercial applications.…”

Catalytic Sulfidation of C12 – C14 α-Olefin Fractions

“…% [8]. It is known that the interaction of the C 16+ -olefin fraction with elemental sulfur in most cases is conducted in the presence of various derivatives of dialkyl dithiophosphoric acid [5,6,9]. The use of these catalysts not only does not require additional purification of the reaction mixture, but also improves the anti-oxidation and anti-corrosion properties of the resulting sulfur-containing products.…”

“…In [5,6] the processes of C 16 -C 18 and C 20 -C 26 -olefin fraction sulfidation for the "Fitrol" oil additives (a mixture of dialkyl dithiophosphoric acid butyl methacrylic ester and zinc dialkyldithiophosphate) were proven effectively catalytic. In the present study the dynamics of change in the content of chemically bound sulfur in the product of elemental sulfur sulfidation of the C 12 -C 14 -olefin fraction were investigated as a function of time in the presence of various derivatives of the dialkyl dithiophosphoric acid at 5 wt.…”
