Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O.
used to make phosphate esters such as tricresyl phosphate: Potassium dichromate: a common inorganic chemical reagent, most commonly used as an oxidizing agent in various laboratory and industrial applications Potassium hydroxide: a strong base; precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals
By some definitions, "organic" compounds are only required to contain carbon. However, most of them also contain hydrogen, and because it is the carbon-hydrogen bond that gives this class of compounds most of its particular chemical characteristics, carbon-hydrogen bonds are required in some definitions of the word "organic" in chemistry.

Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
Methanol is a promising energy carrier because, as a liquid, it is easier to store than hydrogen and natural gas. Its energy density is, however, lower than methane , per kg. Its combustion energy density is 15.6 MJ / L ( LHV ), whereas that of ethanol is 24 and gasoline is 33 MJ/L.
They result in a gas mixture containing acetaldehyde, ethane, ethyl, methane, hydrogen, carbon dioxide, ketene, and formaldehyde. [53] High-temperature pyrolysis (830–1,200 K (557–927 °C; 1,034–1,700 °F)) at elevated pressure in an inert atmosphere leads to a more complex composition of the gas mixture, which also contains acetylene and ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Both industrially and in the laboratory, propionaldehyde has primary application as a chemical building block. [2]: 4 [4] It is predominantly used as a precursor to trimethylolethane (CH 3 C(CH 2 OH) 3) through a condensation reaction with formaldehyde. This triol is an important intermediate in the production of alkyd resins.
