350 °C

Additional information

The melting point of LAS was determined in three different studies. In the first study, the melting point was assessed according to ISO 1218 using photocell detection method. The melting point was >350 degrees C at atmospheric pressure. In the second study, melting point was determined using EU method A.1. A melting point range of 333.2 -388.2 K (60 -116 degrees C) at 102.1 kPa was found. In the third study, the melting point was determined using thermal analysis.
