  • Launchers (Astronautics)
DEF

A chemical which supplies its own oxygen and which helps other combustible material burn more readily.

OBS

The DOT defines an oxidizer or oxidizing material as a substance that yields oxygen readily to stimulate the combustion (oxidation) of organic matter. Chlorate (ClO), permanganate (MnO), and nitrate (NO) compounds are examples of oxidizers. Note that they all contain oxygen (O).

OBS

oxidizing agent: term standardized by ISO.

PHR

Oxidizer pump.

Élément ou composé chimique susceptible de provoquer la réaction avec l'oxygène ou la combustion d'autres substances. [Définition normalisée par l'ISO.]

OBS

comburant : terme normalisé par l'ISO.

DEF

Compound that gives up oxygen easily, removes hydrogen from another compound, or attracts negative electrons.

OBS

[Textiles.] ... the problem is to allow the chemical to oxidize the colouring matter in the vegetable fibres and thus destroy these and give a good white color, without attacking and degrading the cellulose to any extent.

OBS

"Oxidant" is the term most widely used in documents dealing with atmospheric pollution, "oxidizer" is mostly used in the field of water pollution and "oxidizing agent" is the most generic chemical term.

French

Domaine(s)
  • Chimie
DEF

Corps capable de capter des électrons.

CONT

[Traitement des eaux.] Grâce à son puissant pouvoir oxydant, l'ozone est utilisé comme oxydant de tous les sels réducteurs. Ainsi il sert d'agent de traitement pour la déferrisation et la démanganisation de l'eau, faisant passer les sels ferreux et manganeux à l'état d'hydrates ferriques et manganiques qui précipitent et sont alors aisément éliminés par décantation ou filtration.

OBS

[Exemples d'oxydants : ] le chlore, l'iode, le permanganate de potassium, etc.

OBS

oxydation : [...] L'opération opposée est la réduction.

Spanish

Campo(s) temático(s)
  • Química
DEF

Reactivo que por su tendencia a captar electrones, puede originar una reacción de oxidación.

CONT

En trabajos anteriores 2-4 ha sido demostrada la eficacia de la oxidación de alcoholes por un método simple y de bajo costo, con el empleo de soluciones de hipoclorito de sodio como agente oxidante.
