Administrative data

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2008

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

other: see 'Remark'

Remarks:

Test method details available, no data on Guidelines/References/Citations. Slight deviation from EU guideline (not measured in duplicate) but it is expected that duplicate measurement would not have improved accuracy because it is a broad temperature range anyway.

Details on test material:

Lot 08097

The substance was tested by the test house using a trade name that is considered confidential business information. The name assigned to the substance has therefore been changed to Cargill BP-A.

Results and discussion

Melting / freezing point

Melting / freezing pt.:

>= -20 - <= 15 °C

Atm. press.:

1 atm

Remarks on result:

other: The report doesn't report data on decomposition and Sublimation

Any other information on results incl. tables

The DSC analysis showed two peaks:

- Peak: 6.20°C; Area: 288.997 mJ; Delta H: 13.1362 J/g

- Peak: 132.03°C; Area: 267.940 mJ; Delta H: 12.1791 J/g

The event (heat absorption) over the range 60°- 170°C is due to volatilization of water (~3,000 ppm) which is hydrogen bound to the hydroxyl functionality of the substance.
