Transcript of Formaldehyde

FORMALDEHYDE CHEMICAL FORMULA (also known as methanal) Lewis Dot Structure (valence electrons = 12) Physical properties Molecular weight: 30.03 g/mol Colorless gas with a strong odor at room temperature works cited http://www.referatele.com/referate/engleza/online2/FORMALDEHYDE---Physical-Properties-Chemical-Structure-Preparation-Methods-Reactions-Usagem-Danger-Ma.php http://www.atsdr.cdc.gov/toxprofiles/tp111-c3.pdf melting point: -92 C boiling point: -21 C 55% soluble in fresh water Flash point: 60 C Chemical Properties The minimum temperature at which a liquid gives off a vapor in sufficient concentration to ignite Auto-ignition temperature: 300 C The minimum temperature at which a substance will undergo spontaneous combustion http://chemistry.bd.psu.edu/jircitano/IMforces.html dipole-dipole attractions London dispersion forces The force between two molecules close together attractive forces between the positive end of one polar molecule and the negative end of another polar molecule Intermolecular Forces Storage and disposal Real life applications Was used to decaffeinate coffee, made illegal in 1985 plastics, carpeting, clothing, resins, glues, medicines, vaccines and the film used in x-rays used in shampoo and tooth paste (fights bacteria) Intramolecular Bonds Covalent bonds Hydrogen bonds Keep in closed containers and well ventilated areas heavily contaminated items are disposed of as chemical waste in specially marked containers http://water.usgs.gov/admin/memo/policy/wrdpolicy93.044.html
