Key result

Remarks on result:

other: Chemical (CAS No. 54299-17-1) ignites only when the flame of bunsen burner having temperature of 950°C is brought in contact with it.Thus it can be concluded that substance is flammable only at high temperature of about 950°C.

Conclusions:

[4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that [4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone is not auto-flammable.

Executive summary:

[4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that [4-(4-phenoxybenzoyl)phenyl](4-phenoxyphenyl)methanone is not auto-flammable.
