di-, tri- and tetrachlorotetradecane

Melting point / freezing point

Administrative data

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Justification for type of information:

No melt point available as liquid at room temperature. A pour point study was ran in it's place.

Materials and methods

Test guideline

Qualifier:

equivalent or similar to guideline

Guideline:

EPA OPPTS 830.7200 (Melting Point / Melting Range)

Version / remarks:

ASTM D97 - pour point method used.

Principles of method if other than guideline:

1 Pour the sample into the test jar to the level of the graduation mark. Close the test jar with cork carrying the proper thermometer, depending on the expected pour point
2 Adjust the thermometer so the top of the mercury bulb is just below the surface of the sample, see Attachment #1.
3 Heat the sample to 115° F (+5° F), or in the case of high pour point oils, 15-20° F above the expected pour point.
4 Beginning at a temperature about 20° F above the expected pour point cool the sample in the following stages.
4.1 Samples with pour points above 90° F transfer to a cooling bath at 30° F (+5° F).
4.2 Samples with pour points between 90° and 30° F, cool the sample to 95° F at room temperature and then transfer it to the 30° F (+5° F) cooling bath. Four points between 30° and 0° F, transfer to the cooling bath at 0° F (+5° F).
4.3 Samples with pour point of less than 0° F, transfer to the cooling bath at -20° F (+5° F).
5 At each thermometer reading that is a multiple of 5, remove the test jar from the jacket and tilt it just enough to ascertain if there is movement of the sample. (After determining if you reach the pour point, replace the jar quickly.)
6 If the sample in the 30°F cooling bath has not ceased to flow when its temperature has reached 50° F, transfer the test jar to a second bath maintained at 0°F. If the sample in the 0°F bath has not ceased to flow when its temperature has reached 20° F, transfer the test jar to a third bath maintained at –20°F.
7 As soon as the sample in the test jar does not flow when the jar is tilted, hold the jar in a horizontal position for 10 seconds and observe carefully. If there is movement, resume the test. If there is no movement, record the reading of the test thermometer.
8 Add 5° F to recorded temperature and report as the pour point.

Test material

Test material information

Constituent 1

Reference substance name:

di-, tri- and tetrachlorotetradecane

Molecular formula:

Substance is a range of chlorinated isomers of C14 alkane

IUPAC Name:

di-, tri- and tetrachlorotetradecane

Results and discussion

Melting / freezing point

Key result

Melting / freezing pt.:

< -44 °C

Applicant's summary and conclusion

Conclusions:

There is no distinct melting point available. C14 chloroalkane is a liquid at -18 °C and starts to thicken below that. Pour point determined to be -44 °C.

Executive summary:

Using test method ASTM D97, the pour point of di-, tri-, tetrachlorotetradecane was determined to be -44 °C.
