METHOD OF PRODUCING γ, δ-UNSATURATED ALCOHOL Russian patent published in 2021 - IPC C07C29/38 C07C33/25 

FIELD: chemical or physical processes.

SUBSTANCE: present invention relates to a method of producing γ,δ-unsaturated alcohol of general formula (2):

,

where R¹–R³ each independently represents a hydrogen atom, an alkyl group having 1–10 carbon atoms and optionally substituted with a hydroxy group, an alkenyl group, having 2–10 carbon atoms and optionally substituted with a hydroxy group, or an aryl group having 6–12 carbon atoms and optionally substituted with a hydroxy group, provided that R¹ and R³ can bond with each other to form a ring. Method involves reaction of α-olefin, represented by following general formula (1)

,

where R¹–R³ are as defined above, with an aqueous solution of formaldehyde in the presence of alcohol having 3–10 carbon atoms, wherein formaldehyde aqueous solution is subjected to preliminary heating at 30–220 °C before the stage.

EFFECT: disclosed method enables to obtain an end product with high output and good output.
