- Conclusions:
- At 30 °C and above strong exothermal behaviour of MMP Rein (MMP pure) and MMP Roh (MMP raw) was observed. An stability assessment for a 17,500 L tank at environmental temperature of 60 °C and a heat dissipation half life of t1/2 = 60 h resulted in stable storage conditions up to 60 °C. At temperatures > 60 to 90 °C the heat production curves of both MMP Rein and MMP Roh are beneath of the heat dissipation curve.
Reference
Test I:
The test item ANT-A (MMP Rein; MMP pure) was heated from 20 °C to 247 °C. After ca. 27 days the test was stopped. At 30 °C and above strong exothermal behaviour was observed. At 215 °C the test dewar was destroyed. Maximal pressure of 21000 hPa (21 bar) and maximal increase in pressure of 1.4 hPa/sec (1.4 * 10-3 bar/sec) was observed at 215°C (burst of the dewar).
Test II:
The test item ANT-B (MMP Roh; MMP raw) was heated from 20 °C to 110 °C. After ca. 30 days the test was stopped. The reason was a defect of the heating device in the testing apparatus. Therefore the evaluable range of the sample temperature curve endet at 87 °C. At 30 °C and above strong exothermal behaviour was observed. At 87° C a pressure of 9,000 hPa (9 bar) was observed.
Stability assessment:
Based on the results a stability assessment of the following scenario was performed:
The heat dissipation curve for a 17,500 L tank with heat dissipation half life of t1/2 = 60 h and environmental temperatures of 20, 30 40, 50, and 60 °C the heat production rate of both, MMP Rein (ANT-A) and MMP Roh (ANT-B), was calculated. Up to 60 °C the storing conditions of MMP Rein (ANT-A) and MMP Roh (ANT-B) are stable, up to 90 °C the heat production curve of both MMP Rein and MMP Roh are beneath of the heat dissipation curve of the surrounding temperature.
Description of key information
MMP showed a strong exothermal behaviour above 30 °C in a hot storage test. The stability assessment demonstrated stable storage conditions up to 60 °C.
1:1 MMP/acrolein mixtures containing catalyst exhibited no exothermal behaviour at 13 °C - 119 °C.
Additional information
Although MMP showed a strong exothermal behaviour above 30 °C the stability assessment for a 17,500 L tank at environmental temperature of 60 °C and a heat dissipation half life of t1/2 = 60 h resulted in stable storage conditions up to 60 °C. Between 60 °C to 90 °C the heat production curve of MMP was beneath of the heat dissipation curve.
