2-Octanone Usage And Synthesis
- Description2-octanone is a kind of natural ketone found in many sources such as coco, baked peanuts, potato, cheese, beer, banana and oranges. It can be used as a flavor and fragrance ingredient. It is used in the field of fiber, medicine, pesticides and spices for the synthesis of fiber oil, defoamer and the preparation of surfactants, coal flotation agent.
