| chemical properties | colorless or extremely light pale yellow oily liquid. Boiling point 248 ℃, relative density 0.932-0.936, refractive index 1.502-1.503, flash point above 100 ℃, soluble in 4 volumes of 70% ethanol and oily perfume. It has the sweet fragrance of violet, iris and osmanthus, which is the main aroma of iris oil. |
| use | because of its high price, it is less used. It can be used instead of iris coagulum or its extract for iris, violets, osmanthus and high-grade essence formula, which can improve the aroma and obtain sweet fragrance. Because the taste is very powerful sweet, properly diluted with berry-like fragrance, it can be used for edible flavors such as berries and fruit fragrance. GB 2760-1996 regulations are allowed to use food and spices. GB 2760-1996 regulations are temporarily allowed to use edible spices. Mainly used to prepare raspberry, strawberry and other flavors. |
| production method | is formed by condensation of citral and butanone. Made from dimethyl butadiene. |
