Description of key information
Additional information
PETROLEUM GASES: Environmental classification is based on the data for the major components (propane, n-butane and isobutane); these gases have been considered by Environmental Effects Working Group, and it was agreed that they do not meet the criteria for classification as dangerous for the environment. Physical properties indicate that petroleum gases will rapidly evaporate from the aquatic environment and that neither acute, nor chronic toxic effects will be seen in practice. Recommended classification: No classification for environmental effects.[Concave report No. report no. 01/54; Concave report No. 6/05, 2005 ]
PETROLEUM GASES
1. Description
Petroleum gases constitute a group of 91 substances entered in EINECS. They originate
from the distillation of crude oil, or as by-products from other refinery operations in
particular, those involving cracking processes. All are entered in Annex I of the DSD and
for labelling purposes, the short name petroleum gas has been assigned. Commercially,
the most important members of this group are those identified as liquefied petroleum gas
(LPG). The main CAS Nos that are used for LPG are 68476-85-7, 68476-86-8, 92045-80-2
and 68512-91-4. LPG is taken to be representative of petroleum gases in terms of its
environmental properties.
2. Composition/properties
LPG consists predominantly of C3 and C4 hydrocarbons, the main constituents being
propane, n-butane and isobutane [1]. LPG will contain small amounts of hydrocarbons
outside these carbon numbers, notably C5 hydrocarbons. LPG derived from cracking
processes will contain olefinic C3 and C4 hydrocarbons, notably propene, butenes and
butadiene. LPG may also contain sulphur compounds, in particular mercaptans and
organic sulphides. [Concave report No. report no. 01/54]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
