Conclusions:

The Freezing point determination of octyl acetate (CAS No.112-14-1) was done using crushed ice and salt. No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74°C at 974.5 hPa.

Executive summary:

The Freezing point determination of octyl acetate (CAS No.112-14-1) was done using crushed ice and salt. No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74°C at 974.5 hPa.

Description of key information

The Freezing point determination of octyl acetate (CAS No.112-14-1) was done using crushed ice and salt. No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74°C at 974.5 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:

-14.74 °C

Additional information

In an experiment conducted by SSS(Europe)AB,the Freezing point determination of octyl acetate (CAS No.112-14-1) was done using crushed ice and salt. No freezing was observed up to -14.74°C. Hence, the freezing point was inferred to be less than -14.74°C at 974.5 hPa.

Other supporting studies from various reliable sources such as authoritative database and handbook also suggests that the freezing point of chemical was reported to be in the range of -38.5 degree C to -37 degree C.

As the data from lab has K1 reliability and the test was performed using standard methos of analysis which has the value of freezing point temperature as <-14.74 degree degree C thus considered as key study for the chemical safety assessment.
