chemical change

Noun
  1. (chemistry) any process determined by the atomic and molecular composition and structure of the substances involved (synset 113467563)
    referred to in: chemical science, chemistry - the science of matter; the branch of the natural sciences dealing with the composition of substances and their properties and reactions
    is a type of: action, activity, natural action, natural process - a process existing in or produced by nature (rather than by the intent of human beings)
    subtypes:
    • acylation - the process of introducing an acyl group into a compound
    • agglutinating activity, agglutination - the coalescing of small particles that are suspended in solution; these larger masses are then (usually) precipitated
    • amylolysis - conversion of starch to sugar
    • association - (chemistry) any process of combination (especially in solution) that depends on relatively weak chemical bonding
    • blueing, bluing - a process that makes something blue (or bluish)
    • calcification - a process that impregnates something with calcium (or calcium salts)
    • catalysis, contact action - acceleration of a chemical reaction induced the presence of material that is chemically unchanged at the end of the reaction
    • chelation - the process of forming a ring by forming one or more hydrogen bonds
    • chemical reaction, reaction - (chemistry) a process in which one or more substances are changed into others
    • chlorination - the addition or substitution of chlorine in organic compounds
    • cleavage - the breaking of a chemical bond in a molecule resulting in smaller molecules
    • corroding, corrosion, erosion - erosion by chemical action
    • cracking - the process whereby heavy molecules of naphtha or petroleum are broken down into hydrocarbons of lower molecular weight (especially in the oil-refining process)
    • deamination, deaminization - removal of the amino radical from an amino acid or other amino compound
    • decalcification - loss of calcium from bones or teeth
    • decarboxylation - the process of removing a carboxyl group from a chemical compound (usually replacing it with hydrogen)
    • de-iodination - the removal of iodine atoms from organic compounds
    • demineralisation, demineralization - the removal of minerals and mineral salts from a liquid (especially from water)
    • desalination, desalinisation, desalinization - the removal of salt (especially from sea water)
    • digestion - the process of decomposing organic matter (as in sewage) by bacteria or by chemical action or heat
    • dissociation - (chemistry) the temporary or reversible process in which a molecule or ion is broken down into smaller molecules or ions
    • gasification - the process of changing into gas
    • gassing - the process of interacting with gas
    • hydrogenation - a chemical process that adds hydrogen atoms to an unsaturated oil
    • intumescence, intumescency, swelling - the increase in volume of certain substances when they are heated (often accompanied by release of water)
    • inversion - a chemical process in which the direction of optical rotation of a substance is reversed from dextrorotatory to levorotary or vice versa
    • iodination - the substitution or addition of iodine atoms in organic compounds
    • chemical mechanism, mechanism - the atomic process that occurs during a chemical reaction
    • nitrification - the chemical process in which a nitro group is added to an organic compound (or substituted for another group in an organic compound)
    • peptisation, peptization - the process of converting to a sol; bringing to a colloidal solution
    • photosynthesis - synthesis of compounds with the aid of radiant energy (especially in plants)
    • polymerisation, polymerization - a chemical process that combines several monomers to form a polymer or polymeric compound
    • precipitation - the process of forming a chemical precipitate
    • proteolysis - the hydrolysis of proteins into peptides and amino acids by cleavage of their peptide bonds
    • pyrochemical process, pyrochemistry - processes for chemical reactions at high temperatures
    • sequestration - the action of forming a chelate or other stable compound with an ion or atom or molecule so that it is no longer available for reactions
    • synaeresis, syneresis - the separation of liquid from a gel that is caused by contraction (as in cheese making)
    • synthesis - the process of producing a chemical compound (usually by the union of simpler chemical compounds)
    • transamination - the process of transfering an amino group from one compound to another
    • transamination - the process of transposing an amino group within a chemical compound
    • ferment, fermentation, fermenting, zymolysis, zymosis - a process in which an agent causes an organic substance to break down into simpler substances; especially, the anaerobic breakdown of sugar into alcohol
    same as: chemical action, chemical process
