Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 January 2019
- 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:
- no guideline followed
- Principles of method if other than guideline:
- - Principle of test: The temperature of the phase transition from frozen solid to liquid state is determined using a Fisher-Johns Type Melting Point Apparatus.
- Short description of test conditions: The sample material was frozen in a -90°C freezer. A quantity of frozen material was placed on the heating stage of the apparatus. The sample was covered using a thin glass plate and the assembly was slowly heated. The melting point was reached when small drops of liquid appeared on the glass cover. At this point a temperature reading was taken on the electronic thermometer this temperature is known as the freezing point.
- Parameters analysed / observed: Freezing point - GLP compliance:
- no
- Type of method:
- other: Melting/Freezing Point Determination Using Fisher-Johns Type Melting Point Apparatus
- Key result
- Melting / freezing pt.:
- 3 °C
- Atm. press.:
- 101.325 kPa
- Conclusions:
- The average freezing point of the Reaction Mass of 2-propenoic acid, 2-methyl-, 2 dodecylhexadecyl ester and 2-propenoic acid, 2methyl-, 2-tetradecyloctadecyl ester was found to be at 3°C.
- Executive summary:
An experiment was performed using Fisher-Johns type melting point apparatus to determine the freezing point of Reaction Mass of 2-propenoic acid, 2-methyl-, 2 dodecylhexadecyl ester and 2-propenoic acid, 2methyl-, 2-tetradecyloctadecyl ester. The average freezing point of three test runs of Reaction Mass of 2-propenoic acid, 2-methyl-, 2 dodecylhexadecyl ester and 2-propenoic acid, 2methyl-, 2-tetradecyloctadecyl ester was found to be 3°C.
