Key result

Boiling pt.:

363 K

Atm. press.:

2.128 kPa

Decomposition:

yes

Decomp. temp.:

363 K

Remarks on result:

other: corresponding to 89.85 °C

Method 1:

At approximately 403 K, the substance melted to form a red-brown liquid. This liquid became progressively darker before boiling at 533 K.

Method 2:

Temperature (K)	Pressure (kPa)	Observations
298	1.862	The test substance melted, forming a red-brown liquid.
307	2.128	The test substance began to boil and emitted small amounts of white fumes.
321	2.128	The test substance continued to boil but no distillate was collected.
322	2.128	The test substance suddenly 'welled up'.
363	2.128	A red-brown distillate was collected. A black tar-like residue remained.

Conclusions:

D-8 was investigated for boiling temperature according to EU method A.2. The boiling point of D-8 was determined to be 363 K ot 89.85 °C with decomposition, at a pressure of 2.128 kPa.

Executive summary:

D-8 was investigated for boiling temperature according to EU method A.2. Boiling point determination at atmospheric pressure was not possible, because the test item decomposed. Instead, boiling point determination was carried out under reduced pressure, using a standard laboratory procedure not specified in the Official Journal. The boiling point of D-8 was determined to be 363 K or 89.85 °C with decomposition, at a pressure of 2.128 kPa.

Description of key information

D-8 was investigated for boiling temperature according to EU method A.2. Determination at normal atmospheric pressure was technically not feasible, thus, an additional alternative method was used. At a pressure of 2.128 kPa, the boiling point of D-8 with decomposition was determined to be 363 K or 89.85 °C.
