The invention provides novel unsaturated monoaldehydes of general formula
R¹-CH₂-CH(R²)-(CH₂)n-CH=C(CH₃)₂
wherein one of groups R¹ and R² represents a formyl group and the other represents a hydrogen atom and n is an integer from 2 to 8, preferably from 3 to 6, which compounds may be used as fragrants.
The invention further relates to a hydroformylation process for the preparation of the novel unsaturated aldehydes.
本发明提供通式如下的新型不饱和单醛
R¹-CH₂-CH(R²)-(CH₂)n-CH=C(CH₃)₂
其中,基团 R¹ 和 R² 中的一个代表甲酰基,另一个代表氢原子,n 是 2 至 8 的整数,最好是 3 至 6,这些化合物可用作芳香剂。
本发明还涉及一种制备新型不饱和醛的加氢甲酰化工艺。
