What is the difference between the dry point and the final boiling point of oils?
Thread Content
I was introduced to this concept when I was studying * back then. But I heard today that there’s a difference between the two. What is that difference?
Dry point is the temperature at which the last drop in the distillation flask is evaporated during the distillation of oil products. At this point, only the oil turns into a gas and remains in the distillation flask; further distillation is required, and the temperature continues to rise. When no more oil flows out, and the temperature reaches its peak before starting to drop, that temperature is known as the final boiling point. Therefore, the final boiling point is higher than the dry point.
