Formaldehyde has a pungent odor and is very soluble in water. Formaldehyde is highly reactive and readily combines. with many chemical compounds, and under normal conditions, it is a gas. In its simplest form, formaldehyde is a color-. less gas. But the term formaldehyde is sometimes used to describe liquids composed of various mixtures of formalde-. hyde, water, and alcohol.
Forms of formaldehyde. Formaldehyde is more complicated than many simple carbon compounds in that it adopts several different forms. As a gas, formaldehyde is colorless and has a characteristic pungent, irritating odor. Upon condensation, the gas converts to various other forms of formaldehyde (with different chemical formulas) that are of more practical value. One important derivative is the cyclic trimer metaformaldehyde or 1,3,5-trioxane with the formula (CH2O)3. There is also a linear polymer called paraformaldehyde.
