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.
