PROCESS FOR PREPARING CUBIC PI-PHASE MONOCHALCOGENIDES
The invention provides process for preparing tin or germanium monochalcogenides of cubic crystalline structure, the process comprises combining a source of tin or germanium and a source of chalcogenide in a reaction vessel in the presence of uncharged liquid primary amine R—NH.sub.2 and a charged form R—NH.sub.3+ associated with a counter anion, wherein R is saturated or unsaturated hydrocarbyl, which may be the same or different in the uncharged and charged forms, and recovering from the reaction mixture an essentially pure cubic phase of the monochalcogenides.

RAPID SYNTHESIS METHOD FOR BIOMASS-BASED AMINE
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%.
