Where does isopropyl alcohol come from or how is it made?

Isopropyl alcohol does not occur naturally.\nIt is produced from propene by indirect hydration in a\ncomplex process known as "strong-acid process", or by\ndirect catalytic reduction of acetone.

The word is "extract".\n\nAlcohol containing products such as wine, champagne, whiskey, beer etc are made from food products having a lot of carbohydrates like rice, wheat, barley etc. What differs in the wine, whiskey etc. is the amount of alcohol or more precisely Ethanol or C2H5OH, it is obtained on fermentation which breaks up the long starch chains into simpler ethanol molecules.\n\nFermentation is an oxidation reaction, if allowed to continue, C2H5OH is oxidised to Acetic or Ethanoic acid CH3COOH whose diluted form is vinegar.

by distilling non-pure alcohol. (you need the proper equipment though - they do this in like high school chemistry class or something like that). But as far as I know, it's impossible to get 100% pure alcohol, because it will absorb some water vapour from the air, so the closest you can get is lika 99,8% or something.

There are several different types of isomers.  Typically, an isomer has the same chemical formula, with a different arrangement of the molecules.  Isopropanol and n-propanol are a good example of this.\n\nYou can also arrange the molecules of isopropanol (C3H8O) into other compounds, such as methyl ethyl ether.  These are also isomers of that compound.\n\nAnother type of isomer is a stereoisomer, where the chemicals are bound together the same way, the positioning on the chemicals is different -- think of your hands -- same parts, attached to the same other bones, just one is a left hand, and the other is a right.  Mirror images of each other.

Physical and chemical properties\nThe hydroxyl group generally makes the alcohol molecule polar. Those groups can form hydrogen bonds to one another and to other compounds. Two opposing solubility trends in alcohols are: the tendency of the polar OH to promote solubility in water, and of the carbon chain to resist it. Thus, methanol, ethanol, and propanol are miscible in water because the hydroxyl group wins out over the short carbon chain. Butanol, with a four-carbon chain, is moderately soluble because of a balance between the two trends. Alcohols of five or more carbons (Pentanol and higher) are effectively insoluble because of the hydrocarbon chain's dominance.\n\nBecause of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. All simple alcohols are miscible in organic solvents. This hydrogen bonding means that alcohols can be used as protic solvents.\n\nThe lone pairs of electrons on the oxygen of the hydroxyl group also makes alcohols nucleophiles.\n\nAlcohols, like water, can show either acidic or basic properties at the O-H group. With a pKa of around 16-19 they are generally slightly weaker acids than water, but they are still able to react with strong bases such as sodium hydride or reactive metals such as sodium. The salts that result are called alkoxides, with the general formula RO- M+.\n\nMeanwhile the oxygen atom has lone pairs of nonbonded electrons that render it weakly basic in the presence of strong acids such as sulfuric acid. For example, with methanol:

Terephtalic acid (TPA) (or 1, 4-dicarboxyic benzene) is made from 1, 4- dimethylbenzene (or para-xylene). The xylene is oxidized using a catalyst to yield TPA. The xylene is a petrochemical isolated from crude oil.\n\nTPA is then reacted with ethylene glycol to produce the polyester,  first prepared by DuPont and sold under the name DACRON.

Ether, or diethyl ether as it is more correctly called is made by combining ethanol molecules with each other on a catalyst so that ether and water is formed as the product. 2Ethanol + heat + catalyst = 1 diethyl ether + 1 H2O

well they use fermentation and fractional distillation to get the alcohol content high.  some are distilled more than once

Part of pharmaceutical manufacture involves solvents such as isopropyl alcohol which are driven off during the process. Typically, the volatile solvents are incinerated because letting them just go to the atmosphere is considered pollution.  An attractive option to VOC incineration is solvent recovery. This is a process whereby the process hydrocarbon is sent not to an incinerator but to a bed of activated carbon or zeolite. This material has the unique property by which hydrocarbons are highly attracted and adsorb to it. This functionally filters the hydrocarbon from the process stream effectively removing the pollutant.  The hydrocarbon on the carbon may then be de-sorbed and processed such that the hydrocarbon is recovered. The recovered hydrocarbon may then be re-processed, saving the manufacturer the cost for more solvent. This amounts to a huge cost savings in manufacturing the product, as upwards of 95% or more of the solvent is driven off the product and upwards of 98% of the solvent is filtered from the stream. That means that more than 93% of the solvent may be recovered and reused. Solvent recovery systems, when properly applied will actually pay for themselfs in recovered solvent within 2 years.

Ethanol can be made from anything that contains carbon, oxygen & hydrogen. (Which means any plant).\n\nThe simplest way to make it is by allowing yeast to digest sugars (which is how beer & wine are made) and then using the distillation process to separate the ethanol from everything else, but this is by no means the only way.\n\nThe race is on to identify which process produces the most ethanol at the least cost, because ethanol is an unlimited-availability alternative to gasoline, but cost is always an issue.  Current engine designs also demand that they burn gasoline/ethanol mixtures that don't exceed a certain percentage of ethanol, because it burns hotter and would melt regular engines if used pure.\n\nBut I believe we'll figure it out soon enough.

The conditions are different.\n\nCyclohexane has a boiling point of 80.74 °C and isopropyl alcohol has a boiling point of 82.3 °C which is very close.  Separating by distillation would be difficult as both of the liquids would have some vapor pressure at either temp.\n\nGas chromatography uses (or can use) a stationary phase which has a high polarity allowing the cyclohexane to travel through while hindering the alcohol (which would come out of the column later).  The separation is almost always 100 percent.

You can produce benzyl alcohol from benzaldehyde by the crossed Cannizzaro reaction (see link below), but there is a theoretic maximum yield of 50% only.

It looks like an alcohol.  An alcohol has the structure R-O-H, where R is any alkyl (carbon and hydrogen) group.
