Volatility

Regarding the distillation recovered temperatures for gasohol/gasoline in Peru, which are related to the volatility of gasohol/gasoline, samples complied with the national regulatory limit. Excessively high T50 can lead to poor starting and warm-up performance at moderate ambient temperatures. In the case of the final boiling point (FBP), nine samples were above the regulatory limit of 221°C between 2012 and 2019. The average temperature of distillation recovered 10% v/v was 54°C, distillation recovered 50% v/v averaged 96°C, distillation recovered 90% v/v was 160°C and FBP averaged 205°C.
