What does formaldehyde smell like at room temperature?
At room temperature, formaldehyde is a colorless, flammable gas that has a distinct, pungent smell. It is also known as methanal, methylene oxide, oxymethyline, methylaldehyde, and oxomethane.
Why is it important to keep formaldehyde free of methanol?
Formalin free of methanol is also shipped but must be kept warm (about 30°C (86°F)) to prevent polymerization. Pure formaldehyde, a gas, is not handled commercially because it tends to polymerize exothermally and may ignite.
How much formaldehyde is in a saturated water solution?
A saturated water solution, of about 40% formaldehyde by volume or 37% by mass, is called "100% formalin". A small amount of stabilizer, such as methanol, is usually added to suppress oxidation and polymerization. A typical commercial-grade formalin may contain 10–12% methanol in addition to various metallic impurities.
What are the two chemical reactions that produce formaldehyde?
Two chemical reactions on it simultaneously produce formaldehyde: that shown above and the dehydrogenation reaction: CH 3 OH → CH 2 O + H 2 In principle, formaldehyde could be generated by oxidation of methane, but this route is not industrially viable because the methanol is more easily oxidized than methane.
