paraformaldehyde usage and synthesis

chemical properties	white solid
general description	a white solid with a light pungent odor. a linear polymer of formaldehyde of formula ho(ch2 o)xh where x averages about 30. soluble in water when x is less than 12; higher polymers are not immediately soluble. slow dissolution in water proceeds by means of hydrolysis to give fragments of lower x. flammable, although may take some effort to ignite. flash point 158°f. used in fungicides, bactericides, and in the manufacture of adhesives. a hazard to the environment. immediate steps should be taken to limit spread to the environment.
air & water reactions	flammable. forms aqueous solution of formaldehyde, often quite slowly.
reactivity profile	paraformaldehyde may react violently with strong oxidizing agents (hydrogen peroxide, performic acid, perchloric acid in the presence of aniline, potassium permanganate, nitromethane). may react with bases (sodium hydroxide, potassium hydroxide, ammonia), and with nitrogen dioxide (explosive reaction around 180°c). reacts with hydrochloric acid to form highly toxic bis(chloromethyl) ether. polymerization reaction with phenol may develop sudden destructive pressure [bretherick, 5th ed., 1995, p.168]. may generate flammable and/or toxic gases in combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. generates toxic formaldehyde gas when heated. can react with air to give first peroxo acids, and ultimately formic acid. these reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction). incompatible with liquid oxygen.
health hazard	vapor or dust irritates eyes, mucous membranes, and skin; may cause dermatitis. ingestion of solid or of a solution in water irritates mouth, throat, and stomach and may cause death.
fire hazard	behavior in fire: changes to formaldehyde gas, which is highly flammable.
