Applicant's summary and conclusion

Conclusions:
The vapour pressure of the test item at 20 °C (293.15 K) was calculated to: 1.40 × 10-1 Pa (mean of three determinations).
Executive summary:

The isothermal thermogravimetric effusion method was applied for the determination of the vapour pressure of 2-methoxy-5-nitrophenyl acetate.

According to Sponsor the test item 2-methoxy-5-nitrophenyl ace-tate has a melting range from 103 °C to 104 °C. Therefore, the eval-uation of the measurement was done below the melting range.

A value of the vapour pressure of the test item was determined using the data obtained above 60 °C and below 90 °C. The vapour pressure of the test item at 20 °C (293.15 K) was calculated to:

1.40 × 10-1 Pa (mean of three determinations).
