The Chemical Compound Sodium Dichromate

The chemical compound sodium dichromate contains two sodium atoms, two chromium atoms and seven oxygen atoms. It is a powerful oxidizer and is used in laboratory chemistry.

DFT-computed mixing energies show that within this set of compounds, the aforementioned O relaxation displacements are energetically unfavorable irrespective of the B’ cation chemistry (see Supporting Information). The structural results suggest a possible explanation for this observation.


A chemical substance is a form of matter that has constant composition and characteristic properties. It can be a pure substance (such as water or gold) or a mixture, such as a diamond or table salt. A mixture can only be separated into its constituent elements by physical means. A sample of a chemical can be analyzed to determine its exact chemical composition.

A chemist can look at the chemical structure of a compound and predict its potential for undergoing a specific chemical change. These changes produce one or more different types of matter, such as rust forming from iron and oxygen.

A chemist can also describe a chemical property using its molecular formula, which identifies the atoms and bonds that make up a compound. This information can be downloaded as a structural data file (SDF/MOL) from the SMILES string page for O7′-methylistanblamine, and can be converted into two-dimensional drawings or three-dimensional models using a cheminformatics software program.


The use of fossil raw materials in chemistry has negative environmental implications and their replacement by biomass is urgently needed. This is a long-term challenge in which chemists should have an important role to play.

The aim of this Action is to provide a mechanism for developing sustainable industrial chemicals and chemical based consumer products utilising environmentally friendly processes. In order to minimise potential overlaps and utilise the new knowledge generated in existing COST Actions, it is expected that this Action will be interlinked with working groups of other Actions.

The exploitation of renewable feedstocks requires the development of efficient, economically benign and environmentally friendly process methodologies. This research needs to take into account the fact that a lot of energy is used in making and breaking chemical bonds as well as in transforming materials. Therefore engineering aspects should be included from an early stage. This can lower the traditional barriers for introducing green chemicals and processes in conventional and profit oriented industry.
