Oxidation stability of biodiesel<br />
873 Biodiesel Rancimat<br />
A new era in the determination of the oxidation<br />
stability of biodiesel (FAME)<br />
The 873 Biodiesel Rancimat is tailor-made for the<br />
determination of the oxidation stability of biodiesel,<br />
diesel fuel and mixtures of biodiesel with diesel fuel.<br />
The accessories optimized for this application comprise<br />
elongated reaction vessels and special, chemically<br />
resistant connection tubings. To minimize cleaning<br />
expenditure some of the accessories are disposables.<br />
This has the added advantage of significantly improving<br />
the accuracy and reproducibility of the measurements.<br />
The software offers automatic data recording<br />
and evaluation as well as a measurement database<br />
and thus allows the comfortable management of large<br />
amounts of data.<br />
Oxidation stability of biodiesel (fatty acid methyl<br />
esters, FAME)<br />
In addition to other alternative fuels such as ethanol,<br />
methanol or biogas (methane), fatty acid methyl esters<br />
are becoming commercially available; these are also<br />
known as biodiesel, RME (rapeseed oil methyl esters) or<br />
FAME (fatty acid methyl esters). As an alternative, fatty<br />
acid ethyl esters (FAEE) are used in some countries.<br />
Biodiesel has a relatively short storage life as it is slowly<br />
oxidized by atmospheric oxygen. The substances produced<br />
by this decomposition can cause motor damage.<br />
For this reason oxidation stability is an important quality<br />
criterion for biodiesel and is determined regularly<br />
during its manufacture. By using the 873 Biodiesel<br />

Rancimat this determination can be carried out simply<br />
and reliably. The oxidation process can be slowed down<br />
by the addition of antioxidants. The 873 Biodiesel<br />
Rancimat can also be used for determining the effectiveness<br />
of antioxidants.<br />
