What is isopropyl alcohol ?
I requirement to clean my printer..... the feeder Rollers
can i use something else approaching tea tree oil ... or pin polish remover... a non acetone one....
Answer:
Yes - it's rubbing alcohol. But, no I would not use it on the printer as it is pretty strong stuff and might damage your printer elements.
it is your simple rubbing alcohol you get within the little white bottles at any drug store....you could use those forced air can but i wouldnt use anything else but what the manufacturer recommeneds or it could cancelled you warranty
No! Just use rubbing alcohol....it IS isopropyl alcohol!

Isopropyl alcohol (also isopropanol or rubbing alcohol) is a common nickname for propan-2-ol, a colorless, flammable chemical compound with a strong odor. It have the chemical formula CH3CHOHCH3, and is the simplest example of a secondary alcohol, where on earth the alcohol carbon is attached to two other carbons. It is an isomer of propanol.
Sterilizing pads typically contain a 60-70% solution of isopropanol surrounded by water. Isopropyl alcohol is also commonly used as a cleaner and solvent contained by industry. It is also used as a gasoline additive for dissolving marine or ice contained by fuel lines. Isopropanol is the main ingredient contained by rubbing alcohol. It is used as a disinfectant, and is a common solvent.
Isopropanol is a core ingredient in "dry-gas" fuel stabilizer. In significant quantities, marine is a problem in fuel tank as it separates from the gasoline. If the engine tried to combust the water instead of gasoline serious engine problems could result, as dampen cannot be compressed by an engine (see hydrolock). The isopropanol does not remove the water from the gasoline. Rather, the isopropanol solubilizes the marine in the gasoline. Once soluble, the hose does not pose the same risk as insoluble dampen.
It is also a very pious cleaning agent and often used for cleaning electronic devices such as contact pins (like those on ROM cartridges), alluring tape deck and floppy disk drive head, the lenses of lasers in optical disc drives (e.g. disc, DVD) and removing thermal paste from CPUs. It is also used to verbs glass computer monitor screen (at some risk to the anti-reflection coating of the screen), and used by many music shops to confer second-hand or worn library newer looking sheens. It cleans dry-erase boards very capably and other unwanted ink related marks.

[edit] Uses
Sterilizing pads typically contain a 60-70% solution of isopropanol contained by water. Isopropyl alcohol is also commonly used as a cleaner and solvent contained by industry. It is also used as a gasoline additive for dissolving sea or ice within fuel lines. Isopropanol is the main ingredient surrounded by rubbing alcohol. It is used as a disinfectant, and is a common solvent.
Isopropanol is a central ingredient in "dry-gas" fuel stabilizer. In significant quantities, hose down is a problem in fuel tank as it separates from the gasoline. If the engine tried to combust the water instead of gasoline serious engine problems could result, as river cannot be compressed by an engine (see hydrolock). The isopropanol does not remove the water from the gasoline. Rather, the isopropanol solubilizes the hose in the gasoline. Once soluble, the marine does not pose the same risk as insoluble marine.
It is also a very dutiful cleaning agent and often used for cleaning electronic devices such as contact pins (like those on ROM cartridges), alluring tape deck and floppy disk drive head, the lenses of lasers in optical disc drives (e.g. disc, DVD) and removing thermal paste from CPUs. It is also used to verbs glass computer monitor screen (at some risk to the anti-reflection coating of the screen), and used by many music shops to administer second-hand or worn annals newer looking sheens. It cleans dry-erase boards very very well and other unwanted ink related marks.
[edit] Chemistry
Isopropyl alcohol forms an azeotrope next to water at 87.4% alcohol. It is impossible to dehydrate isopropanol further using standard distillation methods. For this justification, more expensive means, such as using a desiccant, are called for for production of 100% isopropyl alcohol.
Being a secondary alcohol, isopropanol can be oxidised to the ketone acetone. This can be achieve using oxidising agents such as chromic acid, or by dehydrogenation of isopropanol over a heated copper catalyst:
(CH3)2CH-OH → (CH3)2C=O + H2
Isopropanol may be converted to 2-bromopropane using phosphorus tribromide, or dried out to propylene by heating beside sulfuric acid. With sodium hydroxide and a halogen, or next to sodium hypochlorite, it undergoes the haloform aversion. This means it would bestow a positive result for an iodoform test.
Isopropanol is normally used as a hydride source in the Meerwein-Ponndorf-Verley let-up.
Like most alcohols, isopropyl alcohol reacts next to active metals such as potassium to form alkoxides which can be call isopropoxides. The reaction next to aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.
Isopropanol has a maximal absorbance at 204 nm contained by an ultraviolet-visible spectrum.
[edit] Safety
Isopropyl alcohol vapour is heavier than nouns and is highly flammable near a very wide-ranging combustible range. It should be kept away from warmth and open flame. When mixed beside air or other oxidizers it can explode through deflagration. [1]
Isopropyl alcohol is oxidized by the liver into acetone. Symptoms of isopropyl alcohol poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, and coma. Use within well-ventilated areas and use protective gloves while using. Poisoning can crop up from ingestion, inhalation, or absorption.
Long residence application to the skin can cause defatting.
[edit] Medicine/Toxicology
Isopropyl alcohol is something like twice as toxic as ethanol. Isopropyl alcohol does not cause an anion space acidosis (like ethanol or methanol). It produces an elevated osmolal gap, but roughly no abnormal anion space (though this may be seen as a result of hypotension and lactic acidosis). Overdoses may incentive a fruity, acetone-like odor on the breath.
