- Executive summary:
The boiling point of the test material was assessed according to OECD test Guideline 103 and EU Method A.2. and in compliance with GLP using the Siwoloboff method.
A boiling tube (3.2 mm diameter) was filled with the sample and heated until liquid. A boiling capillary was then immersed, open end first.
Observations were then recorded as the temperature of the sample was raised.
As the temperature increased, the sample was observed to darken slightly at 240 °C and then turn an amber colour at 280 °C, indicating decomposition. No sign of boiling was noted.

Barometric pressure: 1026 mbar
As the temperature increased, the sample was observed to darken slightly at 240 °C and then turn an amber colour at 280 °C, indicating decomposition. No sign of boiling was noted.
As heating was continued beyond the melting point of the test material the clear, light brown liquid continually darkened in colour indicating decomposition.
Thus the boiling point was not determinable since the test material appears to decompose at temperatures above its melting point. It is possible to estimate the theoretical boiling point of the test material based on its structure. The method described by Meissner is based on the correlation of the normal boiling point with chemical type; molar refraction (RD) and parachor (P) are used as variables in the correlation:
Tb = (637[RD]^1.47 + BP) / [P]
Where:
B is a constant whose value depends upon the chemical type.
RD:
10 carbons = 10 (2.418) = 24.180
11 hydrogens = 11 (1.100) = 12.100
1 oxygen (hydroxyl) = 1 (1.525) = 1.525
1 oxygen (ether) = 1 (1.643) = 1.643
1 oxygen (carbonyl) 1 chlorine = 1 (2.211) = 2.211
1 chlorine = 1 (5967) = 5.967
1 six-membered ring = 1 (0) = 0
3 double bonds =3 (1.733) = 5.199
RD = 52.825
P (McGowan’s Method)
10 carbons = 10 (47.6) = 476.0
11 hydrogens = 11 (24.7) = 271.7
3 oxygens = 3 (36.2) = 108.6
1 chlorine = 1 (62.0) = 62.0
P = 918.3
The test material has 25 bonds in the compound
P = 918.3 – 25 (19)
= 443.3
P (Sugden’s Method)
10 carbons = 10 (9.2) = 92.0
10 hydrocarbons bonded to carbon = 10 (15.4) = 154.0
1 hydrogen bonded to oxygen = 1 (10.0) = 10.0
1 oxygen (hydroxyl) = 1 (20.0) = 20.0
1 oxygen (ether) = 1 (20) = 20.0
1 oxygen (carbonyl) = 1 (39.0) = 39.0
1 chloride = 1 (55.0) = (55.0)
1 six-membered ring = 1 (0.8) = 0.8
3 double bonds = 3 (19.0) = 57
Strains:
(RCOOH) = 1 (-3) = -3.0
(1-R3CCl) = 1 (-6.0) = -6.0
P = -438
B:
The test material has the following relative functional groups:
Monocarboxylic acid = 28 000
Ether = 4 000
Aromatic hydrocarbon = -2 500
B = -29 500
Tb was calculated to be 556 K (283 °C) using McGowan's [P] value, or 562 K (289 °C) using Sugden's [P] value.
A melting curve was registrated from 60 °C to 360 °C with a heating rate of 10K/min (sample weight = 3.48 mg).
At 280 ºC a strong exothermic effect is observed which is interpreted as decomposition.
There is no endothermic effect which is unrelated to the melting point. Therefore, sublimation or boiling of the test material can be excluded.
