Adamantane

Adamantane is a chemical compound that is quite useful in some technological as well as medicinal applications. Read this article to know more about this chemical.

What is Adamantane

It is a crystalline chemical compound. It is a cycloalkane (alkanes having rings of carbon atoms in their molecular structure) and is the simplest diamondoid (structures having resemblance to diamond). It is for this reason that this compound has been named “Adamantane”.

Chemical Formula of Adamantane

This chemical compound has the formula of C10H16.

History and Synthesis of Adamantane

H. Decker was the first person who, at a 1924 conference, suggested that a Hydrocarbon with the chemical formula of C10H16 and a molecular structure like a diamond may exist. He named this molecule “Decaterpene”.

In the same year, the German chemist Hans Meerwein tried to synthesize the compound by reacting Formaldehyde and Diethyl Malonate under the influence of Piperidine. It was the first laboratory-attempt to synthesis this substance. But instead of the desired product Meerwein got 1, 3, 5, 7-tetracarbomethoxybicyclo [3.3.1] nonane-2, 6-dione. The newfound compound was named “Meerwein’s Ester”. It was later used in the synthesis process of Adamantane and all its derivatives. Another German chemist named D. Bottger attempted to obtain the same compound using Meerwein’s Ester but got another derivative of it.

Vladimir Prelog was the first person to successfully synthesize Adamantane from Meerwein’s Ester in 1941. But the process followed by Prelog was too complicated for regular use. In 1956, the process was refined and simplified but it was still not simple enough for regular use. In 1959, Paul von Ragué Schleyer accidentally discovered a much simpler process to produce this substance.

In this process, Dicyclopentadiene was hydrogenated under the influence of a catalyst (e.g. Platinum Dioxide). Then, the resultant product was transformed into Adamantane in the presence of another catalyst (some Lewis acid like Aluminum Chloride). The substance produced in this process was very affordable.

All the mentioned processes produce a polycrystalline powder (solid composed of many small, almost always microscopic crystals) of the compound. It is possible to create single crystals from this powder.

Natural Occurrences of Adamantane

Before Adamantane was obtained through synthesis process, Czech chemists S. Landa and V. Machacek isolated this substance from petroleum in the year 1933. It was done with the help of fractional distillation. Petroleum was heated to a point where only solid impurities were left in it. The ensuing steam was sent through a Fractional Distillation Column. The Column temperature decreased because of the steam. As a result, Hydrocarbon fractions condensed all along the Column according to their different boiling points. Only a few milligram of the substance was produced in this process. But the high melting and boiling points of the compound were noticed.

Structure of Adamantane

A molecule of this compound contains three Cyclohexane rings (a Cycloalkane with chemical formula of C6H12). These are organized in the “armchair” or “chair” conformation (form of stereoisomerism).

The length of the Carbon-Carbon bond in the molecular structure is 1.54 Å (Angstrom.1 Å = 1/10,000,000,000 meter). It is almost identical to the carbon- carbon bond in a diamond molecule. The distance between the Carbon and the Hydrogen in the molecule is 1.112 Å.

Nomenclature of Adamantane

According to the systematic nomenclature rule, the right name for this substance should be tricyclo[3.3.1.13,7]decane. But International Union of Pure and Applied Chemistry (IUPAC) recommend continuing using “Adamantane” as its name.

Production of Adiponitrile

The electrohydrodimerization of Acrylonitrile (ACN) to Adiponitrile is a widely used electro-organic process for the preparation of this compounds. It can be produced by direct electrochemical hydrodimerization of Acrylonitrile in a medium that contains the compound along with electrolyte salt and water. The medium is passed through pairs of electrodes that are 0.05 to 2 mm. apart.

These days, cadmium cathodes and steel anodes are used in a bipolar cell without membranes. Two-phase recirculating aqueous emulsion of ACN, ADN, a bisquaternary salt (hexamethylene(bisethyltributyl)ammonium phosphate), phosphate buffer, anode anticorrosion additives, borax and EDTA is also deployed.  The process of preparation is conducted at a temperature of 55oC (131oF) and density of 2 kA/m2. A portion of the organic phase is continuously removed from the emulsion reservoir for separating the product. The aqueous phase also receives a continuous treatment to avoid organic byproducts and metallic salts accumulating from oxidation of electrode.

This chemical can also be produced from Butadiene. The Butadiene method was pioneered by DuPont and uses natural gas, which makes it sensitive to price fluctuations in natural gas. The Acrylonitrile method uses propylene and is subjected to fluctuation in the price of Propylene.

Like any other combustible substance, CS2 should be stored in a safe storage cabinet away from heat or any source of ignition. The container should be tightly closed and kept in a well-ventilated spot that has a cool temperature.

Personal safety

Individuals using this material should wear lab coat, gloves, splash goggles and vapor respirators to prevent any physical damage arising out of exposure to CS2.

In case of a large spill, these protective equipments should be worn along with full body suits and boots. It is also important to use a self-contained breathing equipment to avoid inhalation of this substance.

Carbon Disulfide Lewis Structure

A Lewis symbol is a type of symbol that represents the electrons located in the valence shell of a simple ion or an atom as dots positioned around the letter that symbolizes the chemical element. In this structure, each dot stands for one electron. The most appropriate Lewis Structure for CS2 can be drawn as Bond Order and Bond Length.

** * *      ** **

S     xx   C   xx   S

**                    **

Structure of Carbon Tetrabromide

This crystalline compound has a monoclinic crystal structure. The molecules of Carbon Tetrabromide are tetrahedral. It means the atoms are arranged in a tetrahedral manner inside each molecule of this compound.

Plastic Crystallinity of Carbon Tetrabromide

The high temperature alpha (α) phase of the Carbon Tetrabromide molecules is called a plastic crystal phase. These molecules are positioned on the corners as well as the center of the faces of the cubic unit cell in an fcc arrangement. Earlier it was believed that the molecules of this compound were able to rotate almost freely (a ‘rotor phase’), which could make them look like spheres after an average time. However, resent studies show them to be restricted to 6 possible orientations (Frankel disorder). In addition, these molecular orientations do not occur entirely independently. Sometimes the bromine atoms of different neighboring molecules come very close to each other leaving little space for independent orientation. This prevents certain orientational combinations between two neighboring molecules. These problems cause significant amounts of disorder inside the crystals of this carbon bromide compound leading to high-structured sheets of diffuse intensity in X ray diffraction. The defense intensity structure provides detailed information about this structure.

Reactions of Carbon Tetrabromide

This crystalline compound is used in the Appel reaction along with triphenylphosphine. Appel reaction is an organic reaction in which alcohols are converted to alkyl bromides. Carbon Tetrabromide is used for this purpose as it shows much less stability than lighter tetrahalomethanes.
