Charalambous, ed s, The Brief Profile summarizes the non-confidential data on substances as it is held in the databases of the European Chemicals Agency ECHAincluding data provided by third parties. The Brief Profile is automatically generated; note that it does not currently distinguish between harmonised classification and minimum classification; information requirements under different legislative frameworks may therefore not be fully up to date or complete.
For accuracy reasons, substance manufacturers and imports have the responsibility to consult official sources, e. The information provided in the free-text fields is not published in the Brief Profiles.

For accuracy reasons, substance manufacturers and importers are responsible for consulting official sources.
The Brief Profile summarises the non-confidential data on substances as it is held in the databases of the European Chemical Agency ECHAincluding data provided by third parties. Due to the quantity of information and the number of chemicals, the Brief Profile is automatically generated based on the information available and is not manually verified.
For sections such as substance use, chemical properties and the classification and labelling of substances, the quantity and quality of the information is the responsibility of manufacturers and importers. While the Agency tries to aggregate the information on chemicals in the best possible way, ECHA cannot check whether all the information provided by industry is free of errors. Brief Profiles are updated regularly and new information is added when available.
Since the source data can be updated at any time while the Brief Profiles are updated at intervals, a slight delay in the publication of information may occur. Furthermore, updates in the source data may not always result in an update of the Brief Profile. For example, an update in a section of a dossier that is not displayed in the Brief Profile will not result in an update of the Brief Profile.
If you have any comments or suggestions, please contact ECHA using our contact form. All the source data on which the summaries on this page are based, is provided by industry and stored in the ECHA databases.
Data from all dossiers registered for the same substance is used in the summarisation and aggregation process, as it is presumed that all data submitted by the registrants is relevant for the substance being registered. If the test material used is different from the substance being registered an indication will be provided.
Please note that the information provided in the free-text fields is not published in the brief profiles. Each endpoint includes three information blocks:. Note: Information presented in this section is generated as part of an automatic process, i. There are four methods to aggregate and summarise data, depending on the available data and endpoint.
An icon is displayed to indicate the type of aggregation and summarisation performed:. When more than one numerical result is available per endpoint the count is displayed between square brackets.
Physical properties of alcohols
For other data an order of magnitude logic might apply; e. Due to the number of the substances and the associated information, substance data is processed and aggregated in an automatic process.
Therefore, data has to fit the format and aggregation logic that is used for the Brief Profile. These study results can however be consulted when opening the source data. If only waived data is available for the substance, following justifications for data-waiving can be displayed in the Brief Profile:. Please see the registered dossiers for substance information for the following endpoints:. In addition, information on the type of substance, origin, number and type of registered compositions and other places where the substance is listed are displayed in this section.

Two additional straight chain isomers of 1-hexanol, 2-hexanol and 3-hexanolexist, both of which differing by the location of the hydroxyl group. Many isomeric alcohols have the formula C 6 H 13 OH.
It is used in the perfume industry. Hexanol is produced industrially by the oligomerization of ethylene using triethylaluminium followed by oxidation of the alkylaluminium products.
The process generates a range of oligomers that are separated by distillation. Another method of preparation entails hydroformylation of 1-pentene followed by hydrogenation of the resulting aldehydes. This method is practiced in industry to produce mixtures of isomeric C 6 -alcohols, which are precursors to plasticizers.
In principle, 1-hexene could be converted to 1-hexanol by hydroboration diborane in tetrahydrofuran followed by treatment with hydrogen peroxide and sodium hydroxide :.
Unknown List by Melting Point & Boiling Point
This method is instructive and useful in laboratory synthesis but of no practical relevance because of the commercial availability of inexpensive 1-hexanol from ethylene. Alarm pheromones emitted by the Koschevnikov gland of honey bees contain 1-hexanol. CisHexenalanother volatile organic compoundis also considered responsible for the freshly mowed grass flavor.

Methyl alcohol, ethyl alcoholand isopropyl alcohol are free-flowing liquids with fruity odours. The higher alcohols—those containing 4 to 10 carbon atoms—are somewhat viscous, or oily, and they have heavier fruity odours. Some of the highly branched alcohols and many alcohols containing more than 12 carbon atoms are solids at room temperature. The boiling points of alcohols are much higher than those of alkanes with similar molecular weights.
Such a large difference in boiling points indicates that molecules of ethanol are attracted to one another much more strongly than are propane molecules. Most of this difference results from the ability of ethanol and other alcohols to form intermolecular hydrogen bonds. See chemical bonding: Intermolecular forces for a discussion of hydrogen bonding.
This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Hydrogen bonds, with a strength of about 5 kilocalories 21 kilojoules per mole, are much weaker than normal covalent bondswith bond energies of about 70 to kilocalories per mole.
The amount of energy per mole that is required to break a given bond is called its bond energy. Water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
Because alcohols form hydrogen bonds with water, they tend to be relatively soluble in water. Methanol, ethanol, n -propyl alcohol, isopropyl alcohol, and t - butyl alcohol are all miscible with water. Because they are strongly polar, alcohols are better solvents than hydrocarbons for ionic compounds and other polar substances. Article Media. Info Print Print. Table Of Contents. Submit Feedback.

Chinese USA.The boiling point of alcohol depends on which type of alcohol you're using, as well as the atmospheric pressure.
The boiling point decreases as atmospheric pressure decreases, so it will be slightly lower unless you are at sea level. Here is a look at the boiling point of different types of alcohol. The boiling point of ethanol or grain alcohol C 2 H 5 OH at atmospheric pressure One practical application of the different boiling points of alcohols and of alcohol with respect to water and other liquids is that it can be used to separate them using distillation.
In the process of distillation, a liquid is carefully heated so more volatile compounds boil away. They may be collected, as a method of distilling alcohol, or the method may be used to purify the original liquid by removing compounds with a lower boiling point. Different types of alcohol have different boiling points, so this can be used to separate them from each other and from other organic compounds. Distillation may also be used to separate alcohol and water. The boiling point of water is F or C, which is higher than that of alcohol.
However, distillation can't be used to fully separate the two chemicals. Many people believe alcohol added during the cooking process boils away, adding flavor without retaining alcohol.
The reason is that alcohol and water bind to each other, forming an azeotrope. The components of the mixture can't be easily separated using heat. The only way to completely remove alcohol from a liquid is to boil it away completely or allow it to evaporate until it's dry. Share Flipboard Email. Anne Marie Helmenstine, Ph. Chemistry Expert.
