The term higher alkanes is sometimes used literally as "alkanes with a higher number of carbon atoms". One definition distinguishes the higher alkanes as the n-alkanes that are solid under natural conditions. Alkanes from nonane to hexadecane those alkanes with nine to sixteen carbon atoms are liquids of higher viscositywhich are less suitable for use in gasoline. They form instead the major part of diesel and aviation fuel. Diesel fuels are characterised by their cetane numbercetane being an older name for hexadecane.

However the higher melting points of these alkanes can cause problems at low temperatures and in polar regionswhere the fuel becomes too thick to flow correctly. Mixtures of the normal alkanes are used as boiling point standards for simulated distillation by gas chromatography. Alkanes from hexadecane upwards form the most important components of fuel oil and lubricating oil.

In latter function they work at the same time as anti-corrosive agents, as their hydrophobic nature means that water cannot reach the metal surface. Many solid alkanes find use as paraffin waxused for lubricationelectrical insulationand candles. Paraffin wax should not be confused with beeswaxwhich consists primarily of esters. Alkanes with a chain length of approximately 35 or more carbon atoms are found in bitumen asphaltused for example in road surfacing.

However, the higher alkanes have little value and are usually split into lower alkanes by cracking. This group of n-alkanes is generally liquid under standard conditions.

More information about the EC Inventory can be found here. If the substance was not covered by the EC Inventory, ECHA attributes a list number in the same format, starting with the numbers 6, 7, 8 or 9. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance.

If generated, an InChI string will also be generated and made available for searching. More help available here. CAS no. The CLP Regulation makes sure that the hazards presented by chemicals are clearly communicated to workers and consumers in the European Union. The source of the information is mentioned in the introductory sentence of the hazard statements.

When information is available in all sources, the first two are displayed as a priority. The purpose of the information provided under this section is to highlight the substance hazardousness in a readable format.

It does not represent a new labelling, classification or hazard statement, neither reflect other factors that affect the susceptibility of the effects described, such as duration of exposure or substance concentration e. Other relevant information includes the following:. Harmonised classification and labelling is a legally binding classification and labelling for a substance, agreed at European Community level. If the substance is covered by more than one CLH entry e. It is possible that a harmonisation is introduced through an amendment to the CLP Regulation.

The quality and correctness of the information submitted to ECHA remains the responsibility of the data submitter.Nonacosane has also been identified within several essential oils. It can also be prepared synthetically. It has 1, constitutional isomers. The "Iris kerneriana" rhizomes contain; tetradecanoic acid Nonacosane occurs naturally and has been reported to be a component of a pheromone of "Orgyia leucostigma", and evidence suggests it plays a role in the chemical communication of several insects, including the female "Anopheles stephensi" a mosquito.

Other compounds found in passion flowers are coumarins e. Many flavonoids and their glycosides have been found in "Passiflora", including apigenin, benzoflavone, homoorientin, 7-isoorientin, isoshaftoside, isovitexin or saponaretinkaempferol, lucenin, luteolin, n-orientin, passiflorine named after the genusquercetin, rutin, saponarin, shaftoside, vicenin and vitexin.

Maypop, blue passion flower "P. Also documented to occur at least in some "Passiflora" in quantity are the hydrocarbon nonacosane and the anthocyanidin pelargonidindiglycoside. Members of "P. These are composed of a complex mixture containing dimethylalkanes, n-alkanes, and monomethylalkanes. They are straight-chain and have methyl branches. These serve to protect the wasps from dehydration.

Their composition tends to be unique to each species of wasp. Hydrocarbons are present on the surface of workers, males, eggs, and larvae, as well as the surface of the nest and its pedicel. The lipids in the nest paper probably function in kin recognition among workers, while those in the pedicel likely deter predators.

In ants, the necrophoric response is defined as the behavior of recognizing dead colony members and carrying them to a refuse pile away from the nest.

Adult males have the hydrocarbon compounds as the workers, but they are present in different amounts. Nest paper and pedicel have much larger hydrocarbon units, between 27 and 31 carbons in length. The pedicel also contains hexadecanoic acid and octadecanoic acid.Nonacosane [ 1 ].
