Properties and stability
Colorless oily liquid. It has a strong herbal aroma and a slightly bitter taste. Boiling point is 66°C (2666Pa). Insoluble in water, soluble in ethanol. Natural products are found in bananas, papayas, peppermint oil, Scottish spearmint oil, roast beef, corn wine, strawberries, etc. It does not corrode metal when dry and has the chemical reactivity of secondary alcohols.
Storage method
Can be stored in iron, mild steel, copper or aluminum containers.
Synthesis method
Originated from the catalytic hydrogenation of ethyl butyl ketone.
Purpose
Food spices. Mainly used for preparing spices and flavors. It is a solvent and diluent for coatings, a defoaming agent for flotation ores and an intermediate for organic synthesis.
