clear colorless to slightly yellow liquid | [Uses]
Dibutyl phosphite was used as anti-wear agent in bio-based lubricating oil. | [General Description]
Dibutyl phosphite undergoes addition reaction with Schiff bases to yield 1,4-bis[N-methyl(dibutoxyphosphonyl)-1-(2-furyl)]diaminobenzene and 4,4′-bis[N-methyl(dibutoxyphosponyl)-1-phenyl]benzidine. It is antiwear and extreme-pressure additive in industrial gear oils. | [Flammability and Explosibility]
