- Specific details on test material used for the study:
- Name: Reaction mass of 2-methylbutyrate and pentyl butyrate
EC number: 908-712-1
Description: Clear colorless to pale yellow liquid
Purity: 99.8% (multi-constituent)
35.06% - 2-Methylbutyl butyrate
64.74% - Pentyl butyrate
Storage conditions: Controlled room temperature (15-25°C, ≤70% relative humidity)
Safety precautions: Routine safety precautions (gloves, goggles, face mask, lab coat) for unknown materials were applied to ensure personnel health and safety. - Auto-ignition temperature:
- 350 °C
- Atm. press.:
- >= 97.3 - <= 97.7 kPa
- Conclusions:
- The auto-ignition temperature of Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was considered to be 350°C in air at atmospheric pressure.
- Executive summary:
The auto-ignition temperature is a measure of the tendency of flammable substances to ignite in contact with hot bodies when mixed with air and makes it possible to classify them from a safety point of view.
A small sample of the liquid test item was injected into a uniformly heated 500 mL glass flask containing air at a predetermined temperature (based on the preliminary experiment).
The lowest internal flask temperature at which hot-flame ignition occurred for a series of prescribed sample volumes was taken to be the hot-flame auto-ignition temperature of the chemical in air at atmospheric pressure.
The auto-ignition temperature of Reaction mass of 2-methylbutyl butyrate and pentyl butyrate was considered to be 350°C in air at atmospheric pressure.

RESULTS
Temperature was measured during each experiment at the outside and inside of the flask. The temperature distribution was steady outside the flask. The test was carried out at 97.3-97.7 kPa atmospheric pressure.
The measured auto-ignition temperature of the reference item (n-Heptane) was 223°C, hence the study was considered to be valid.
In the preliminary test hot-flame ignition of the test item occurred, therefore the main test was performed.
The main test was performed with a volume of 200 µL sample. The starting temperature was approximately 400°C. The temperature was reduced with small increments, until the auto-ignition temperature could be determined with an accuracy of about 3°C. The ignition delay time was determined in each case when ignition was observed.
The lowest temperature at which the sample still showed ignition was about 350°C. This result was confirmed by control measurements: no auto-ignition occurred at about 348°C and below.
The details of the measurements are summarized in Table 1
