Etymology of PROPYLENE OXIDE

The word "propylene oxide" is composed of two parts: "propylene" and "oxide".

1. Propylene: The term "propylene" comes from the Greek word "propylon", meaning "before the gate". It is a combination of "pro", meaning "before" and "pylē", meaning "gate". The word refers to the position of propylene in relation to the related compound, ethylene.

2. Oxide: The word "oxide" originates from the combination of "oxy-" derived from the Greek word "oxys", meaning "acid", and "-ide", used to denote a compound. "Oxys" refers to a sharp or sour taste, which is one of the characteristics of acids. Therefore, "oxide" represents a compound formed from oxygen and another element.
