Ethyl Alcohol, Absolute
Ethanol, also known as Ethyl Alcohol, is a volatile, straight-chain, primary alcohol. It is commonly used as an organic solvent for non-polar substances due to its versatility and miscibility with water. Absolute Ethanol is a common microbiology reagent as a disinfectant and antiseptic for sanitizing lab equipment. It works by denaturing bacterial, fungal, and viral proteins.

Description
Junyuan Petroleum Group’s Ethanol, Absolute is provided at >199 proof and Molecular Biology Grade. It is most effective as a disinfectant when used at 70% with water, which we also provide in a ready-to-purchase product. When combined with Hydrogen Peroxide, it is especially effective at removing bacterial spores as well.
Ethanol, Absolute is the ideal choice for an organic solvent; ready to be used with our many antibiotics and plant growth hormones. Junyuan Petroleum Group offers everything needed for DNA and RNA purification, of which Ethyl Alcohol is an important tool. To qualify as “absolute,” the ethyl alcohol must contain no more than one percent water. In other words, absolute alcohol is liquid alcohol that is at least 99 percent pure alcohol by weight. Ethanol is a colorless liquid with molecular formula C2H5OH. It is the alcohol found in alcoholic beverages.
Junyuan Petroleum Group’s products are supplied for LABORATORY RESEARCH USE ONLY. The product may not be used as a drug, agricultural or pesticidal product, food additive or as a household chemical.

| Reactivity | It can react vigorously, violently or explosively with oxidizers When Ethanol comes in contact with Platinum or Sodium, it liberates flammable hydrogen gas It can react vigorously or explosively with acid hydrides or acid chlorides It reacts with alkali metals to liberate flammable hydrogen gas It reacts with acetyl bromide to evolve hydrogen bromide It reacts with ammona + silver nitrate to form silver nitride and silver fulminate Ethyl alcohol can react with freshly cut/etched/scratched aluminum with the evolution of heat and release of hydrogen gas. The Ethyl alcohol has to be on the aluminum surface as it is being cut/scratched/etched |
Ethanol
Ethanol is a volatile, flammable, simple, organic alcohol. Available in various reagent grades, it has applications as a lab/medicinal solvent, an antiseptic, a fuel source/additive, a precursor to organic compounds, etc.
Denatured alcohol (CAS 64-17-5), also known as denatured ethanol or industrial methylated spirit (IMS), is ethanol (ethyl alcohol) to which has been added small known quantities of other substances, so as to ‘denature’ or adulterate it in a controlled manner.
What Additives are Used in Denatured Alcohol?
Often, the additive is methanol (at 5 to 10%), but isopropanol (IPA), methyl ethyl ketone (MEK), acetone or methyl isobutyl ketone (typically all at 1%) may be used. Denatonium can be added for a bitter taste, colored dyes such as methyl violet for visual identification, or a combination may also be used. The purpose of these additives is to create ethanol that is not suitable for human consumption.
The primary purpose of denaturation is to render the ethanol unfit, unpalatable, and unsafe for recreational human consumption, or unsuitable for any other unauthorized purpose. Denaturation usually makes the product exempt from duty payable and other taxes, making it cheaper to purchase.
How Is Denatured Alcohol Used?
Denatured alcohol is used commercially and in industry:
• As a general-purpose solvent, especially for removal of adhesives, waxes, and paint
• For cleaning and degreasing apparatus and equipment
• As a fuel for burners and stoves
• As a surface disinfectant or sterilizer for use in cleanrooms, laboratories, and clinical environments, presented as a liquid, spray, gel, or pre-moistened wiper
• As a preservative and antibacterial agent in cosmetics
Denatured alcohol with added methanol is acutely toxic. It is flammable at room temperature and storage in a secure location is recommended. Due attention should also be given to all other appropriate precautions necessary for handling these chemicals.
Chemical Properties
Applications
Ethanol is used in antibacterial hand sanitizer gels, as an antidote to methanol poisoning and an antitussive agent. It is acting as a solvent to remove the paint and ink stain on curtains, dress and upholstery. It is utilized as a fuel in camping and primus stoves. It is likewise employed to clean the windows, manufacturing nail-polish and to test pectin levels in jam and jelly making. It finds application in personal care products such as mouthwashes, perfumes and deodorants.

Hazards:
Even though ethanol is very commonly used, it is a dangerous chemical. It is highly flammable, it has exact flash points which are important to know when using it. While ethanol is consumed when drinking alcoholic beverages, consuming ethanol alone can cause coma and death. Ethanol may also be a carcinogenic. However, ethanol is a toxic chemical and should be treated and handled as such, whether at work or in the home.
Absolute Ethanol is also known as Pure Alcohol, Ethanol Absolute, Ethanol, Ethyl Alcohol and simply Alcohol. It is the alcoholic element of intoxicating drinks and as such, duty must be paid to the government when purchasing Absolute Ethanol; this is usually included in the price. However, Absolute Ethanol itself is not intended for human consumption.Get best price for Ethanol, CAS No. 64-17-5, C2H5OH of packaging size 200 litre drum.

Safety Information:
Ethanol Absolute is undenatured anhydrous ethanol, also known as 100% ethyl alcohol, only able to be supplied to holders of a suitable Customs permit.
This is industrial ethanol = ethyl alcohol made from an industrial process to ensure it is pure and anhydrous.
Ethanol Absolute is clear and pure, it contains no dye or no bitrex, and has a pleasant alcoholic odour.
It possesses a low boiling point, a high rate of evaporation, and high solvent power.
Ethanol Absolute finds applications in hand sanitiser, laboratory solvent, conservation work in museums and galleries, perfumery, inks, paints, lacquers, adhesives, nail polish and nail polish remover, fuel, electronics cleaning and dewatering, and as a clean-up solvent for fibreglassing.
Ethanol can be used as a cleaning agent, where its fast evaporation speeds up the process and often prevents the need to clean the surface afterwards.
This fast evaporation lends itself useful in sanding wood, as it helps draw dust and shavings out from between the grains leaving a visibly cleaner product than could be achieved with water.
