| 摘要 |
3-Methyl-2-butenyl 3,3-dimethyl-4-pentenoate, by-product in the condensation between 3-methyl-2-butene-1-ol and a lower alkyl orthoacetate, can be recycled into the condensation by alkoxylating it with a lower alkyl alcohol or orthoacetate in the presence of a basic ester exchange catalyst. |
