Major industries with exposure to strong inorganic acid mists include those that manufacture phosphate fertilizer, isopropanol (isopropyl alcohol), synthetic ethanol (ethyl alcohol), sulfuric acid, nitric acid, and lead batteries. Exposure also occurs during copper smelting, and pickling and other acid treatment of metals (Suresh, 2009).

What Is the Connection between Ethanol and Sulfuric Acid?
Sep 14, 2019· The connection between ethanol and sulfuric acid involves at least three possible reaction pathways. They are esterification — involving either one or two molecules of ethanol, or alcohol — and dehydration, again involving either one or two alcohol molecules.

esterification alcohols and carboxylic acids
Esters can also be made from the reactions between alcohols and either acyl chlorides or acid anhydrides. Making esters from alcohols and acyl chlorides (acid chlorides) If you add an acyl chloride to an alcohol, you get a vigorous (even violent) reaction at room temperature producing an ester and clouds of steamy acidic fumes of hydrogen chloride.

Alcohol Reactivity
Two such oxidants are Jones reagent (a solution of sodium dichromate in aqueous sulfuric acid) and pyridinium chlorochromate, C 5 H 5 NH (+) CrO 3 Cl (–), commonly named by the acronym PCC and used in methylene chloride solution. In each case a chromate ester of the alcohol substrate is believed to be an intermediate, which undergoes an E2like elimination to the carbonyl product.

Dehydration of Alcohols | MendelSet
Jul 19, 2011· An alcohols (OH) is not a very good leaving group, because after it dissociates from a molecule it becomes a negatively charged hydroxide ion. Far better would be to first protonate the alcohol. This way it leaves the molecule as water which has no charge and is very stable. Phosphoric acid gets this job done.
