    摘要： A porous cellulose acetate molding containing an odoriferous substance is provided which is prepared by incorporating an odoriferous substance in a porous molding comprising cellulose acetate having a combined acetic acid of 50 to 58%, a pore volume of at least 0.65 cc/g and a collapsing strength of at least 10 kg. Said porous cellulose acetate may be one which is surface-saponified. Examples of the odoriferous substances include volatile substances such as insect repellents, antibacterials and mold inhibitors. Said porous cellulose acetate molding can adsorb the odoriferous substances fully without substantially changing its shape and persistently volatilize the substance for a long time.
