1-Formylpiperidine is a highly-ordered, dipolar aprotic liquid. Its high boiling point and wide liquid range (—30.6° to 222°C), make it an ideal solvent for non-volatile applications in gas absorption processes, ink and dye systems, and plastics modifiers and stabilizers. It is a powerful solvent for both polar and non-polar compounds. Miscible liquids include long and short chain alcohols, esters, ketones, amides, carboxylic acids and anhydrides, amines, alkyl halides (including Cn and higher homologs), stearates, ethers, alkanes below C?, olefins, nitriles, nitro compounds, pyridines and other heterocyclics, organophosphorus compounds, organotin compounds, organosilicates, and inorganic acids. Solubility of gases and of inorganic compounds in 1-formylpiperidine is similar to those observed in dimethylformamide. Of particular importance is the high solubility of many polymers in this solvent and a

number of applications are reported in polymer technology. The compound is a uniquely versatile liquid having the notable ability to be fully soluble in both water and hexane. The chemical properties of 1-formylpiperidine are similar to dimethylformamide and it forms complexes with many reagents. Its higher boiling point can be of particular advantage in anionic displacement reactions. It is readily purified and dried by simple distillation; once dry it will absorb water from the atmosphere only slowly. Specifications, data, and bibliographic material are available upon request.
