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).
