| Alexander Mikhailovich Butlerov had hydrolyzed methylene acetate while trying to form methyl glycol and produced formaldehyde gas. |
| The chemicals that most often exceeded limits were naphthalene, formaldehyde and acetaldehyde. |
| At room temperature, formaldehyde is an extremely reactive colorless gas with a suffocating odor. |
| Presumably now the formaldehyde has cleared from his brain, he has woken up to the meaning of what he said. |
| The fumes also contain sulfur dioxide, and various aldehydes, primarily formaldehyde as well as acetaldehyde and acrolein. |
| It occurs synthetically as a byproduct in the manufacture of acetaldehyde and formaldehyde and during the atmospheric oxidation of turpentine. |
