Solubility: Miscible (NIOSH, 2016); Miscible (NIOSH, 2016); Miscible (NIOSH, 2016); 13.20 M; In water, 4.00X10+5 mg/L at 20 ?; In water, miscible at 25 ?; In water, 95 weight % at 20 ?; Soluble in ethanol and chloroform; miscible with ether, acetone and benzene; In water, 2X10+5 mg/L at 18 ?.; Slowly soluble in cold , more readily soluble in hot water, with evolution of formaldehyde; Soluble in fixed alkali hydroxide solution; insoluble in alcohol, ether; INSOL IN MOST ORG SOLVENTS.; The higher polymers are insoluble in water.; The rate at which paraformaldehyde dissolves (hydrolyzes) in water is at a minimum at pH 3-5; it increases rapidly at lower or higher pHs.; 400 mg/mL at 20 ?; Solubility in water: very good; Solubility in water: miscible; Solubility in water: poor; Miscible Stability: On standing, especially in the cold, may become cloudy, and on exposure to very low temperature ppt of trioxymethylene formed; in air it slowly oxidizes to formic acid /40% solution/.;Formaldehyde gas is stable in the absence of water.; Depolymerizes readily, especially upon heating or in presence of alkalis or acids.;... /Formaldehyde Lozengens, containing 10 mg paraformaldehyde/ are liable to deteriorate on storage.
