Additional information

THFMA is reported to be a colourless to slightly yellowish liquid at 20°C and 1013 hPa and has an ester-like odour (visual and olfactory assessment during test on physicochemical properties (melting point/boiling point)).

 

THFMA is reported to undergo glass transition (amorphous solidification) at -113°C (determined according to OECD guideline 102, adopted 27th July 1995, and EU Method A.1, December 1992; differential scanning calorimetry).

 

Theboiling point of THFMA is reported to be 222°C at 1020 hPa (determined according to OECD guideline 103, adopted 27th July 1995 and EU Method A.2, December 1992; differential scanning calorimetry).

 

The relative density of THFMA is reported to be 1.042 (determined according to DIN51757; oscillating densitimeter).

 

In accordance with column 2 of REACH regulation annex VII, a granulometry test does not need to be conducted as the substance is a liquid.

 

The vapour pressure of THFMA is reported to be 0.27 mbar at 20°C (no details on method).

 

The n-Octanol/Waterpartition coefficient (log Kow) of THFMA was determined according to OECD Guideline 117 (2004) and EU method A.8 (2008) using the HPLC method. The log Kow was 1.76 ± 0.08 at 22.6°C.

 

The water solubility of THFMA is reported to be 18990 mg/L at 20°C (determined according to OECD guideline 105, adopted 27 July 1995 and EU method A.6, December 1992; flask method).

 

In accordance with column 2 of REACH regulation annex VII, surface tension testing does not need to be conducted. Based on structure, no surface activity is expected. The test substance is not used as detergent.

 

The flash point of THFMA is reported to be 99°C at 1013.25 hPa (determined according to EU method A.9, December 1992; Pensky-Martens closed cup method).

 

The auto-ignition temperature of THFMA was determined according to EU test method A.15, 30 May 2008, and DIN 51794). The auto-ignition temperature of THFMA is reported to be 240°C at 999.8 to 1007.3 hPa.

 

According to REACH Regulation (Annex XI, 1.), the study on flammability  does not need to be conducted if the available data are sufficient for assessment. For THFMA, tests on flash point and auto-ignition are available. Pyrophoricity and flammability on contact with water are not expected based on a consideration of the structure of the substance.

 

In accordance with column 2 of REACH regulation annex VII, explosive properties testing does not need to be conducted as there are no chemical groups associated with explosive properties in the molecule.

 

In accordance with column 2 of REACH regulation annex VII, oxidising properties testing does not need to be conducted on the basis of chemical structure.

 

The kinematic viscosity of THFMA was determined with a micro-Ubbelohde viscometer at 20°C and 40°C (according to OECD guideline 114, adopted 12 May 1981, and DIN 51562).

Kinematic viscosity at 20°C: 2.74 mm²/s

Kinematic viscosity at 40°C: 1.84 mm²/s
