Record 2 2012-08-20

English

Subject field(s)
  • Chemistry
OBS

Aliphatic olefins have straight or branching carbon chains, while alicyclic olefins one or more rings of carbon atoms in the molecule. If the molecule contains only one double bond, it is called a monoolefin. ... In the Geneva system of nomenclature, the aliphatic olefins with one ... double bond are called alkenes ...

French

Domaine(s)
  • Chimie
DEF

Résine vinylique (au sens chimique du terme) provenant de la polymérisation et/ou de la copolymérisation d'hydrocarbures non saturés. [Définition normalisée par l'AFNOR et reproduite avec son autorisation.]

English

Subject field(s)
  • Chemical Elements and Compounds
  • Aliphatic or Acyclic Hydrocarbons
Universal entry(ies)
CnH2n
formula, see observation
DEF

Unsaturated acyclic hydrocarbon with a single double-bond (carbon-carbon).

OBS

The suffixe -ene designates hydrocarbons with one or more double bonds.

OBS

Chemical formula: CnH2n

French

Domaine(s)
  • Éléments et composés chimiques
  • Hydrocarbures aliphatiques ou acycliques
Entrée(s) universelle(s)
CnH2n
formula, see observation
DEF

Hydrocarbure insaturé acyclique à une seule double liaison carbone [...]

OBS

En français, on trouve parfois le synonyme, incorrect mais usuel, oléfine (olefin en anglais). Les oléfines, en effet, en plus de désigner les alcènes, peuvent désigner d'autres hydrocarbures à plusieurs doubles liaisons carbone, par exemple les diènes, appelés aussi dioléfines ou alcadiènes (diene, alkadiene ou diolefin en anglais).

OBS

Formule chimique : CnH2n.

English

Subject field(s)
  • Chemical Elements and Compounds
  • Pollutants
CONT

Fluoroalkenes. Even with double-bonded fluorocarbons, we still can have fairly high lethal concentrations and fairly low toxicity. When you get down to this fellow, perfluoroisobutylene, it is extremely toxic. Hexafluoropropylene, which is used as an intermediate in polymer production, is moderately toxic via inhalation.

OBS

fluorinated alkene; fluoroalkene: generic terms.
