Paragraph 0006; 0012-0017, (2021/11/21)
The invention discloses a method for synthesizing farnesyl acetone. The method comprises the following steps of: mixing nerolidol and aluminum oxide, heating, dropwise adding methyl acetoacetate, carrying out heat preservation reaction after dropwise adding, evaporating generated methanol in the reaction process, and collecting generated carbon dioxide gas; and after finishing the reaction, filtering and separating aluminum oxide, and carrying out reduced pressure distillation on filtrate to collect the product farnesyl acetone. According to the method, the reaction yield is high, a catalyst can be separated through filtration and can be reused, washing of the reaction materials is avoided; waste water and waste containing metal ions are not generated, so that pollution to the environment is avoided; and generated by-products including methanol and carbon dioxide can be recycled.

A process for the manufacture of gamma-delta-unsaturated ketones of formula (R1)(R2)C = CH - CH2 - CH2 - CO - R3 (I), wherein R1 is methyl or ethyl; R2 is a saturated or unsaturated linear or cyclic hydrocarbon residue and R3 is methyl or ethyl, by reacting a tertiary vinyl carbinol of formula (R1)(R2)C(OH) - CH = CH2 (II) with an isopropenyl methyl or ethyl ether of formula H3C-C(OR3) = CH2 (III) in the presence of an ammonium salt as catalyst.
