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.

Test material

Constituent 1
Chemical structure
Reference substance name:
Soybean oil, epoxidised, reaction products with methanol and water
EC Number:
700-080-3
Cas Number:
752225-55-1
IUPAC Name:
Soybean oil, epoxidised, reaction products with methanol and water
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.
