Cyclohexane

Posted on by Guilherme Campos

Cyclohexane

CAS: 110-82-7

Cyclohexane also known as CYX, hexamethylene, hexahydrobenzene, hexanaphthene, and benzenehexahydride is a colourless, volatile, and flammable liquid with the molecular formula C6H12, CAS: 110-82-7. It has a mild odour and is insoluble in water but soluble in alcohol, ether, acetone, benzene, and ligroin.  Cyclohexane occurs naturally in petroleum crude oil, volcanic gases and cigarette smoke.

Production

Cyclohexane can be produced by two methods.  The first is the catalytic hydrogenation of benzene using rhodium on carbon, and the second method is via fractional distillation of petroleum.

It has a specific gravity of 0.78 and a flashpoint of -20° C and is highly flammable

Uses

Cyclohexane is used predominately in the nylon industry where approximately 90% of it is consumed in the industrial production of adipic acid and caprolactam, which are themselves used to generate nylon6 and nylon6.6.  The rest is used both as a solvent for paints, resins, varnish and oil, and as a plasticiser.  Cyclohexane can also be used as an intermediate in the manufacture of other industrial chemicals such as cyclohexanone and nitrocyclohexanone.

Iso Propyl Alcohol- Iso propanol

CAS: 67-63-0

Iso Propyl Alcohol or Iso Propanol or 2-propanol is a structural isomer of propanol and has the molecular formula of C3H8O, CAS: 67-63-0.  It is a clear, colourless liquid and has a distinctive strong alcohol or acetone-like odour.  This solvent is highly flammable, with a flashpoint of around 11 – 13° C.  Iso propanol is soluble in most solvents, including water.

Production

Iso propanol is chemically manufactured by combining water and propene through indirect hydration or direct hydration.  The indirect hydration method is a reaction between propene and sulphuric acid to create sulphate esters.  This product then undergoes hydrolysis.  This method can use a low quality propene because of the mixture with sulphuric acid.  The direct method manufactures the product by reacting propene and water in with an acid catalyst.  The propene for this method needs to be of a high quality.  In both the above methods, the mixture of water and by-products need to go through a distillation process to separate out the iso propanol.

Uses

The largest use of iso propanol is as a solvent, cleaning product and a chemical intermediate.  It can be found in paints, thinners for wood furnishings, inks, cosmetics, toiletries, household cleaning products, specialist cleaning products and room sprays.  It can also be used as an anti-freeze and plays an important part in making the water component of petrol more soluble so that it doesn’t freeze.  Iso propanol can also be used as a biological specimen.

Toluene

CAS: 108-88-3

Toluene is a clear water-insoluble solvent with a molecular formula of C7H8, CAS: 108-88-3.  It has an aromatic, benzene-like smell and is a highly volatile flammable liquid with a flash point of 4° C.  It is obtained from petroleum and coal tar.

Production

Toluene is naturally released into the atmosphere from the following: petroleum fuels, toluene-based solvents, thinners and from motor vehicle exhaust fumes.  The current method to chemically manufacture toluene is through a catalytic reforming process.  A hydrocarbon mixture which is rich in aromatics is passed over a dehydrated catalyst and then obtained from a cut of the distillation or solvent extraction process.

Uses

The main chemical use of toluene is to make benzene, xylenes and other solvents. 

It can also be used to manufacture other chemicals such as phenol, nitrobenzene, benzoic acid and benzyl chloride. 

As a solvent, toluene can be used in paints, paint thinners, adhesives, inks, resins, cleaning agents, leather tanners and inks.  It can also be used to manufacture polymers that produce nylon, plastic soda bottles and for pharmaceuticals, dyes and cosmetic products.  Toluene is also used as a coolant in sodium cold traps underneath nuclear reactor loops.

Cyclohexanone

CAS: 108-94-1

Cyclohexanone also known as Oxocyclohexane, pimelic ketone, cyclohexyl ketone, and CYC is a clear oily liquid that has a colourless to light yellow tinge, a pungent odour and has the molecular formula C6H10O, CAS:108-94-1. It has a specific gravity of 0.945 and a flash point of 46 °C. It is slightly soluble in water and is completely miscible with common solvents.  It occurs naturally in crude oils and is also produced synthetically, in large quantities, as it is a key intermediate in the production of nylon.

Production

Production of cyclohexanone is based on the hydrogenation of benzene or by the oxidation of cyclohexane, in air, and typically in the presence of cobalt crystals.

Uses

Cyclohexanone is an important industrial chemical as it is a chemical intermediate used in the production of specific target molecules.  In fact, the consumption of cyclohexanone is linked almost entirely to the nylon industry with derivatives of it used to produce adipic acid and caprolactam, which are precursors for nylon 6. 

Other cyclohexanone derivatives are used for the synthesis of pharmaceuticals, dyes, herbicides, pesticides, plasticizers and rubber chemicals.

N-Butyl Acetate

CAS: 123-86-4

N-Butyl Acetate is a chemical compound with a molecular formula of C6H12O2, CAS: 123-86-4. It is commonly used as a solvent in the production of lacquers, inks and adhesives.  This product is a colourless liquid that has a fruity odour.  This product is highly flammable with a flash point of 24° C. It is highly miscible with all common organic solvents (alcohols, ketones, glycols, esters) but has only slight miscibility in water.

Production

The most common method for creating n-butyl acetate is via the esterification of a butanol isomer and acetic acid which are heated in the presence of a strong acid.

Uses

The most common use of normal butyl acetate is as a solvent in the production of lacquers and paints.  Its other major use is in the creation of adhesives and hardened coatings.  N-butyl acetate is also used in the pharmaceutical industry as a solvent or an extraction agent.  Its minor uses include cosmetic products, fragrance solvent in perfumes, as an anti-corrosive agent, in cleaning and car care products.  It is also used in the synthetic fruit flouring industry.
