Olefin or "alkene" is a class of hydrocarbons having one or more double bonds between the C-atom obtained by cracking naphtha or other petroleum fractions at high temperatures. Those olefins containing one double bond are called alkenes, and those with two are called alkadienes, or diolefins
Tradenames. There are several tradenames depending on first of all the producer of the product but also on the number of C-atoms of the olefins in the mixture in question. For example, Chevron Philips will give the tradename AlphaPlusTM C14-16-18 for one of their Olefins, but the IBC product name shall be Olefins (C13+, all isomers)
Therefore, it is very important to obtain the correct IBC product name and not only accept the tradename before loading
For information: The IBC code shows 4 (four) different entries for "Olefin mixtures". Which entry to apply depends on the composition of the Olefin mixture to be carried, namely the number of carbon (C) atoms. The four different Olefin mixtures are:
Olefin Mixture (C7-C9) C8 rich, stabilised
Olefin mixture (C5-C7)
Olefin mixture (C5-C15), and
alpha-Olefins (C6-C18) mixtures
