Fatty acids, C16 and C18-20 (even numbered, unsaturated), 2-ethylhexyl esters

Boiling point

Link to relevant study record(s)

Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

23 July 2010

Reliability:

1 (reliable without restriction)

Rationale for reliability incl. deficiencies:

test procedure in accordance with generally accepted scientific standards and described in sufficient detail

Qualifier:

according to guideline

Guideline:

other: Guideline not listed

Principles of method if other than guideline:

A condenser was used to collect any distillate from the substance, with a thermometer measuring the temperature of the test substance, and a second thermometer to monitor the condensate temperature. The sample was heated through a range of 150 ºC to 270 ºC, with the temperature of the condensate monitored throughout.

GLP compliance:

no

Type of method:

distillation method

Key result

Decomposition:

yes

Decomp. temp.:

ca. 160 °C

The sample was not observed to boil during the test. At approximately 160 ºC, the sample was observed to ‘smoke’ with no evidence of distillation, and no temperature rise at the condenser. The sample was noted to be darker in colour. Heat was continually applied until the sample reached 270 ºC. The sample was not observed to boil, and there was no evidence of distillation. GC analysis of the sample after heating showed evidence of degradation.

Conclusions:

The boiling point of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters cannot be determined as the substance begins to degrade before boiling at ca. 160 oC.

Executive summary:

The sample was not observed to boil during the test. At approximately 160 ºC, the sample was observed to ‘smoke’, with no evidence of distillation, and no temperature rise at the condenser. The sample was noted to be darker in colour. Heat was continually applied until the sample reached 270ºC. The sample was not observed to boil, and there was no evidence of distillation. GC analysis of the sample after heating showed evidence of degradation.

The boiling point of Fatty acids, C12-20 and C12-20-unsatd., 2-ethylhexyl esters cannot be determined as the substance begins to degrade before boiling at ca. 160 ^oC.
