93 °C
Atm. press.:
977.5 hPa
Interpretation of results:
other: Non-flammable
Conclusions:
The flash point determination of p-tolyl acetate (CAS No. 140-39-6) was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 93°C at 977.5hPa.
Executive summary:

The flash point determination of p-tolyl acetate (CAS No. 140-39-6)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 93°C at 977.5hPa. Based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the substance p-tolyl acetate (CAS No. 140-39-6) was considered to be non-flammable.

Description of key information

The flash point determination of p-tolyl acetate (CAS No. 140-39-6)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 93°C at 977.5hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
93 °C

Additional information

Various studies for the p-tolyl acetate (CAS No. 140-39-6) were reviewed to summarize the following information:

The flash point determination of p-tolyl acetate (CAS No. 140-39-6)was done following closed cup method using Pensky-Martens flash point apparatus. The test was conducted in replicates and mean flash point was found to be 93°C at 977.5hPa.

From the available handbook, the flash point of p-tolyl acetate(CAS No.- 140-39-6) was determined to be 95 degree C.

As per the available data for flash point from laboratory report and handbook, the flash point value determined was in range from 93 degree C to 95 degree C. As the data from laboratory report has K1 reliability and the test was performed using OECD guidelines which has the value of flash point as 93 °C at977.5 hPa within the range thus considered as key study for the chemical safety assessment. Also based on criteria mentioned in CLP regulation the chemical has flash point >than 60 degree C hence the p-tolyl acetate (CAS No.- 140-39-6) was considered to be non-flammable.
