Abstract: The present invention provides a cigarette filter material useful for selectively and efficiently reducing formaldehyde while maintaining a palatable component such as nicotine or tar. The cigarette filter material is obtained by coating-treating a substrate (such as a cellulose acetate fiber) with a solution (particularly, an aqueous solution) containing a polysaccharide having an amino group (e.g. chitosan) and a polar solvent (e.g., water) [and optionally an acid such as a hydroxy acid (e.g., lactic acid)]. A cigarette filter of such a cigarette filter material can efficiently and selectively reduce formaldehyde.

Abstract: A mixture containing hydrogen iodide and water and having a water content of not more than 5% by weight (particularly not more than 3% by weight) in a distillation system is distilled to prevent condensation of hydrogen iodide in the distillation system. The mixture may comprise hydrogen iodide, water, methanol, methyl iodide, acetic acid, and methyl acetate.

Such a process (distillation process) effectively inhibits condensation of hydrogen iodide in the distillation system and corrosion in the distillation system.
