ALIPHATIC HYDROCARBON [4 records]

Record 1 2017-09-14

English

Subject field(s)
  • Aliphatic or Acyclic Hydrocarbons
CONT

Chlorinated Aliphatic Hydrocarbons (CAHs), a family of compounds that are commonly used as chlorinated organic solvents, are increasingly being detected in soil and groundwater. The most prevalent of these CAHs are perchlorethylene (PCE), trichloroethylene (TCE), and trichloroethane (TCA) ...

French

Domaine(s)
  • Hydrocarbures aliphatiques ou acycliques
CONT

Les hydrocarbures aliphatiques chlorés sont obtenus par chloration des alcanes correspondants, par addition de chlore ou de chlorure d'hydrogène à des composés insaturés, par réaction entre le chlorure d'hydrogène ou la chaux chlorée et des alcools, aldéhydes ou cétones et, exceptionnellement, par chloration du sulfure de carbone, ou d’une autre manière.

Record 2 2009-07-28

English

Subject field(s)
  • Chemistry
  • Solvents and Petroleum Spirits
CONT

This non-solvated crystalline material is more pure than the material produced by the processes described in the literature. The present material is free of aluminum impurities, as well as, chlorinated aliphatic hydrocarbon solvents and aromatic solvents. This non-solvated crystalline form is particularly preferred for use in the manufacture of pharmaceutical compositions.

Key term(s)
  • hydrocarbure aliphatique
  • hydrocarbure acyclique

English

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

Halogenated aliphatic hydrocarbons (HAHs), e.g., carbon tetrachloride, are among a group of chemicals that have been shown to induce oxidative stress.

French

Domaine(s)
  • Éléments et composés chimiques
  • Chimie du pétrole
  • Agents de pollution
CONT

Élimination des micropolluants organiques. [...] Notre attention se porte donc sur les PAHs (hydrocarbures polycycliques aromatiques) tels que le naphtalène, phénanthrène, anthracène, les PCBs (polychlorobiphényles), les détergents et leurs dérivés, les PCDD/F (polychlorodibenzodioxines/furannes) et divers pesticides en ce qui concerne l'accumulation dans les boues et les HAHs (hydrocarbures aliphatiques halogénés) tels que le chloroforme, le trichloréthylène ou le perchloréthylène, en ce qui concerne l'accumulation dans les effluents (ERU).
