Interpretation of results:

non flammable

Remarks:

Migrated information Not classified as a flammable liquid

Conclusions:

The lower and upper explosion limit of benzoyl chloride in air was determined at 760 Torr and at a temperature around 170°C. The method used is unknown and no further details on the experiment are available.The authors found a lower explosion limit of 2.5 vol% and an upper explosion limit of 27 vol%.
According to the CLP regulation n°1272/2008, only liquids with a flash point inférior or equal to 60°C have to be considered as flammable substances. Since flash point of benzoyl chloride is strictly superior to 60 °C, this substance should not be classifeid as a flammable liquid.

Executive summary:

The autors estimated the lower and upper explosion limit in air of benzoyl chloride. They determined their values at 760 Torr and at a temperature of 170°C. In the test conditions, they estimated the lower explosion limit in air at 2.5 % and the upper explosion limit in air at 27 %. No information on the material and methods are known as any further details on this experiment.

Therefore, this study should be considered as not sufficiently documented and thus not assignable.

However, the classification on the flammability of benzoyl chloride is possible. And hence, according to the CLP regulation n°1272/2008, benzoyl chloride should not be classified as flammable liquid since its flash point inférior is superior to 60°C.
