摘要:
A microreactor having a reaction mixture inlet, a reaction mixture channel, and a reaction mixture outlet is provided, in which a piezoelectric material that generates surface acoustic waves and has, formed on the surface thereof, a thin film having catalytic activity is disposed in the reaction mixture channel so that the inner surface of the reaction mixture channel is configured from the thin film. The thin film having catalytic activity can be constituted of a material selected from a group consisting of metals, metal oxides, and complexes of organic compounds. The microreactor attains remarkable improvements in the effect of stirring a reaction mixture and catalysis, whereby a chemical reaction can be evenly and efficiently accelerated. The microreactor is free from channel clogging and pressure loss and hence renders a stable and precise chemical reaction possible.

The invention is related to ionic compounds, derivatives of malononitrile, in which the anionic load has been displaced. An ionic compound disclosed by the invention includes an anionic portion combined with at least one cationic portion M+m in sufficient number to ensure overall electronic neutrality; the compound is further comprised of M as a hydroxonium, a nitrosonium NO+, an ammonium —NH4+, a metallic cation with the valence m, an organic cation with the valence m, or an organometallic cation with the valence m. The anionic portion corresponds to one of the formulas RD—Y—C(C≡N)2− or Z—C(C≡N)2− in which Z is an electroattractive group, RD is an organic radical, and Y is a carbonyl, a thiocarbonyl, a sulfonyl, a sulfinyl, or a phosphonyl. The compounds can be used notably for ionic conducting materials, electronic conducting materials, colorants, and the catalysis of various chemical reactions.
