Small fire while using BBr3


Although literature says BBr3 is non pyrophobic chemical, observed little fire while quenching the used Syringe with methanol.
Can any one explain the reason

BBr3 reacts very enthusiastically with any source of hydroxyl groups. It probably heated up the methanol enough that it caught fire.

Pyrophoric usually means "liable to ignite spontaneously on exposure to air". You did not expose the coumpound to air - you reacted it with some other substance, methanol, which is described as "highly flammable" by CDC, although its autoignition temeperature in air is as high as 470°C, so ignition is improbable at atmospheric pressure.

Pyro-PHOBIC (scared of fire) he wrote....not Pyro-PHORIC (bringing fire/setting into fire)

Hoppefully BBr3 is not chemo-phobic ;):D:P:)
