Key result
Boiling pt.:
ca. 255.7 °C
Atm. press.:
ca. 1 001.7 hPa

The preliminary study and final measurements were performed under atmospheric pressure of 1001.7 hPa.

The preliminary study was carried out in order to determine the boiling temperature range for 1-(2,4-dichlorophenyl)ethan-1-one. The average value of an initial boiling point was approximately 250.0 °C when heated at 10.0 °C per minute in the range of 120-400 °C.

Conclusions:
The boiling point of the test item was observed at temperature of 255.7 ± 0.5 °C under atmospheric pressure of 1001.7 hPa.
Executive summary:

Determination of the boiling point was performed in accordance with the OECD No. 103, EEC A.2 method and with GLP.The boiling point was determined using capillary tube in metal block (1.4.4. Method according to Siwoloboff), which is in conformity with the OECD Guideline for Testing of Chemicals no 103 “Boiling point”. The capillary tube in heated metal block method was used with the BÜCHI Melting Point B-565 apparatus. The measurements were performed in three samples of the test item. The boiling point of the test item was observed at temperature of 255.7 ± 0.5 °C under atmospheric pressure of 1001.7 hPa.
