A rapid synthesis method for a biomass-based amine, including: using formamide as an amine source, formic acid as a hydrogen source, and biomass aldehyde or ketone as a raw material, conduct rapid heating promoting direct addition of formamide and aldehyde or ketone compound through microwave-assisted heating and without a solvent and catalyst, and carrying out formic acid reduction preparing and obtaining a corresponding formamide derivative; selectively converting the formamide derivative under the action of a base into a corresponding primary amine through alcoholysis. The microwave-assisted heating reaction system has a significantly higher catalytic efficiency than a corresponding oil bath system, greatly shortens a reaction time, and significantly improves selectivity, where a conversion rate of a biomass aldehyde or ketone compound may reach at least 99%, and a formamide derivative yield may reach 85-99%; the formamide derivative is synthesized to a primary amine through alcoholysis, where a yield may reach 92-99%.
