AmmoniaAmmonia is an inorganic chemical compound of nitrogen and hydrogen with the formula NH3. A stable binary hydride and the simplest pnictogen hydride, ammonia is a colourless gas with a distinctive pungent smell. It is widely used in fertilizers, refrigerants, explosives, cleaning agents, and is a precursor for numerous chemicals. Renewable ammonia is considered as an important energy carrier in future energy systems.
Organic compoundOrganic compounds are a subclass of chemical compounds of carbon. Little consensus exists among chemists on the exact definition of organic compound; the only universally accepted definition is the quasi-tautological "organic compounds are the subject matter of organic chemistry". Generally, any large chemical compound containing a carbon–hydrogen or carbon–carbon bond is accepted as an organic compound.
EthanolamineEthanolamine (2-aminoethanol, monoethanolamine, ETA, or MEA) is a naturally occurring organic chemical compound with the formula H2NCH2CH2OH or C2H7NO. The molecule is bifunctional, containing both a primary amine and a primary alcohol. Ethanolamine is a colorless, viscous liquid with an odor reminiscent of ammonia. Ethanolamine is commonly called monoethanolamine or MEA in order to be distinguished from diethanolamine (DEA) and triethanolamine (TEOA).
PHIn chemistry, pH ( or ; ) is a logarithmic scale used to specify the acidity or basicity of aqueous solutions. Acidic solutions (solutions with higher concentrations of hydrogen (H) cations) are measured to have lower pH values than basic or alkaline solutions.
Functional groupIn organic chemistry, a functional group is any substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. This enables systematic prediction of chemical reactions and behavior of chemical compounds and the design of chemical synthesis.
TriolIn chemistry, a triol is an organic compound containing three hydroxyl groups (−OHfunctional groups), such as glycerol.Chemical formulaA chemical formula is any of several kinds of notation for expressing the composition and structure of a chemical compound. Chemical formulas use element symbols for the atoms of each chemical element in a compound. There are several conventional types of chemical formula that present different levels of detail.MoleculeA molecule is a group of two or more atoms that are held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions that satisfy this criterion. In quantum physics, organic chemistry, and biochemistry, the distinction from ions is dropped and molecule is often used when referring to polyatomic ions.
Alcohol (chemistry)In chemistry, an alcohol (from Arabic al-kuḥl'the kohl') is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom. Alcohols range from the simple, like methanol and ethanol, to complex, like sugar alcohols and cholesterol. The presence of an OH group strongly modifies the properties of hydrocarbons, conferring hydrophilic (water-attracted) properties.
TonneThe tonne ( or ; symbol: t) is a unit of mass equal to 1,000 kilograms. It is also referred to as a metric ton in the United States to distinguish it from the non-metric units of the short ton and the long ton. One tonne is equivalent to approximately 2,204.6 pounds, 1.102 short tons, and 0.984 long tons. The exact corresponding SI unit is the megagram (symbol Mg), a less common way to express the same mass.
AmineIn chemistry, amines (, UK also ) are organic compounds that contain carbon–nitrogen bonds. Amines are formed when one or more hydrogen atoms in ammonia are replaced by alkyl or aryl groups. The nitrogen atom in an amine possesses a lone pair of electrons. Amines can also exist as heterocyclic compounds.*As an Amazon Associate I earn from qualifying purchases.
