Additional information
The aim of this study was to determine the boiling point of the test substance, Azuril (Reaction mass of 3-(4-methyl-3-pentenyl)cyclohex-3-ene1-carbonitrile and 4-(4-methyl-3-pentenyl)cyclohex-3-ene1-carbonitrile). The test was carried out using a digital melting point device (Buchi B540 Melting Point Unit) with a temperature range up to 400 °C (673 K), following a method in line with OECD 103 and EU Method A.2 guidelines.
For the determination of the boiling point, the capillary method was used. A small amount of the test substance was heated in the electronic controlled sample block. The sample was observed visually whilst the temperature was raised. A phase transformation from liquid to vapour usually is deduced by the formation of bubbles. The test material was assessed visually for any possible changes in its appearance, consistency and colour. The initial temperature of boiling or other effects observed was registered with the corresponding heating temperature.
Following this method, the boiling point of the test material, Azuril (Reaction mass of 3-(4-methyl-3-pentenyl)cyclohex-3-ene-1- carbonitrile and 4-(4-methyl-3-pentenyl)cyclohex-3-ene-1-carbonitrile) was determined to be 297.4 ± 0.91 °C.
