formaldehyde usage and synthesis
chemical properties clear liquid
air & water reactions the solution gives up formaldehyde vapors readily. these vapors are flammable over a wide vapor-air concentration range. water soluble.
reactivity profile formaldehyde, solution, reacts violently with strong oxidizing agents (hydrogen peroxide, performic acid, perchloric acid in the presence of aniline, potassium permanganate, nitromethane). reacts 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].
health hazard the probable oral lethal dose for humans is 0.5-5 g/kg, or between 1 ounce and 1 pint for a 150 pound person. acute -- below 1 ppm, odor perceptible to most. 2-3 ppm, mild tingling of eyes. 4-5 ppm, increased discomfort, mild lacrimation. 10 ppm, profuse lacrimation; can be withstood only for few minutes. 10-20 ppm, breathing difficult, cough, severe burning of nose and throat. 50-100 ppm, acute irritation of respiratory tract, very serious injury likely. skin -- primary irritation from strong solutions, gas. delayed -- sensitization dermatitis. suspected carcinogen. effects in women include menstrual disorders and secondary sterility. solutions splashed in eyes have caused injuries ranging from severe, permanent corneal opacification and loss of vision to minor discomfort. in people sensitized to formaldehyde, late asthmatic reactions may be provoked by brief exposures at approximately 3 ppm.
fire hazard toxic vapors such as carbon dioxide and carbon monoxide are generated during combustion. explosion hazard: when aqueous formaldehyde solutions are heated above their flash points, a potential for explosion hazard exists. high formaldehyde concentration or methanol content lowers flash point. reacts with nitrogen oxides at about 180; the reaction becomes explosive. also reacts violently with perchloric acid-aniline, performic acid, nitromethane, magnesium carbonate, and hydrogen peroxide. when heated, irritant formaldehyde gas evolved from solution. the main products of decomposition are carbon monoxide and hydrogen. metals such as platinum, copper, chromia, and alumina also catalyze the formation of methanol, methylformate, formic acid, carbon dioxide, and methane. reacts with peroxide, nitrogen oxide, and performic acid causing explosions. can react with hydrogen chloride or other inorganic chlorides to form bis-chloromethylether (bcme), a known carcinogen. very reactive, combines readily with many substances, 40% solution is powerful reducing agent. incompatible with amines, azo compounds, dithiocarbamates, alkali and alkaline earth metals, nitrides, nitro compounds, unsaturated aliphatics and sulfides, organic peroxides, oxidizing agents, and reducing agents. aqueous solutions are unstable. commercial formaldehyde-alcohol solutions are stable. gas is stable in absence of water. avoid oxidizing and alkaline materials. hazardous polymerization may occur. compound will polymerize with active organic materials such as phenol. will polymerize violently in the presence of caustics and nitrides; (amines) exothermic reaction, (azo compound) exothermic reaction giving off nitrogen gas, (caustics) heat generation and violent polymerization, (dithiocarbamates) formation of flammable gases and toxic fumes, formation of carbon disulfide may result, (alkali and alkaline earth metals) heat generation and formation of a flammable hydrogen gas.
