Blending compatibility of high-octane gasoline
Thread Content
What changes occur in the dry point when two types of gasoline with different dry points are mixed together? For example, if gasoline with a dry point of 190 degrees and gasoline with a dry point of 160 degrees are mixed together, will the dry point change? Can it become 180 degrees?
Some things cannot be reconciled; there are no overlapping rows
A knowledge point in laboratory analysis. Dry point and final boiling point. The two may seem the same, but they are actually different. When different oil grades are blended, the maximum dry point remains unchanged, but the final boiling point decreases. This is also why oils can be blended. Additionally, the term \"dry point\" doesn’t have much practical meaning; what we usually refer to as the dry point is actually the final boiling point. It’s just that people are used to calling it the \"dry point\" historically, and that name is still in use today.
Why does the final boiling point decrease after mixing?
