Description of key information

Read across substance:

  • Triethylene glycol butyl ether: 278C @ 1atm (handbook value)
  • Commercially produced substance (tri and tetraethylene glycol butyl ether): 255-295C, 267 -331 @ 1013hPa
  • QSAR prediction: 291C

For 3,6,9,12-tetraoxahexadecan-1-ol:

  • QSAR prediction: 333C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
320 °C

Additional information

A reliable QSAR predicts the boiling point to be 333C. For bridging purposes, it is also instructive to look at the prediction for the closely related substance triethylene glycol butyl ether. For this substance, the same QSAR predicts a boiling point of 291C but also cites a experimental value of 278C (ref Clayton & Clayton, 1982). This figure of 278C is also cited in other sources as a measured value for the boiling point and is consistent with measured data from a commercially produced product that consists primarily of triethylene glycol butyl ether and tetraethylene glycol butyl ether (3,6,9,12-tetraoxahexadecan-1-ol). This suggest that the QSAR slightly over estimates the boiling point by around 12C. The boiling point can therefore be deduced with some confidence to be ~320C and this figure is used as the key parameter for this end point.
