- Conclusions:
- Using a linear heating rate of 0.5 °C/min, the boiling point of Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was found to be 188.6 ± 0.95°C, i.e. 461.7 ± 0.95 K (95% confidence interval).
- Executive summary:
The boiling point of the test item was determined by the capillary method using a metal heating block. The principle of study was based on the Siwoloboff method. A smallamount of the test item filled in a capillary was heated with 0.5 °C/minute rate. Duringthe controlled heating the appearance, consistency and colour of the liquid sample wereobserved and registered. The boiling point corresponds to the temperature where airbubbles are continuously formed inside the liquid sample.
The boiling point of Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was found to be 188.6 ± 0.95 °C, i.e. 461.7 ± 0.95 K (95% confidence interval).
Reference
The reference measurements, the preliminary and the main tests were carried out at 97.2 - 97.4 kPa atmospheric pressure.
Using a linear heating rate of 0.5 °C/min, the boiling point of Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was found to be 188.6 ± 0.95 °C, i.e. 461.7 ± 0.95 K (95% confidence interval).
The details are summarized in Table 1.
