< -20 °C
Atm. press.:
101 325 Pa
Decomposition:
no

 Room Temperature  5.3 °C  -20.7 °C  -80 °C

 Colourless,

clear liquid

Still liquid like at

room temperature

More viscous than at

but still liquid

Only at the surface

was pierce able, otherwise

solid like ice

Conclusions:
In a pre-test, the test item 6-sec-butylquinoline was still unfrozen and liquid at – 20.7 °C. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation, the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.
Therefore, no additional test was conducted and the melting point is stated as: < - 20 °C (< 253.15 K)
Executive summary:

In a pre-test, the test item 6-sec-butylquinoline was still unfrozen and liquid at – 20.7 °C. According to REGULATION (EC) No 1907/2006 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL, Annex VII, dated 18. December 2006 (and further amendments) by Commission Regulation, the determination of the melting- / freezing point does not need to be conducted below a lower limit of - 20 °C.

Therefore, no additional test was conducted and the melting point is stated as: < - 20 °C (< 253.15 K).
