Why Formaldehyde is Called Poisonous Alcohol?

how it is prepared? The indirect process reacts with propane with sulfuric acid to form a mixture of sulfate esters. Subsequent hydrolysis of these esters produces isopropyl alcohol. Direct hydration reacts with propane and water, either in gas or liquid phases, at high pressures in the presence of solid or supported acidic catalysts. Both processes require that the isopropyl alcohol be separated from water and other by-products by distillation.

Isopropyl alcohol and water form a zoetrope and simple distillation gives a material which is 87.9% by weight isopropyl alcohol and 12.1% by weight water. Isopropyl alcohol is made by azeotropic distillation of the "wet" isopropyl alcohol.

Isopropyl alcohol is oxidized by the liver into acetone by alcohol dehydrogenises. Symptoms of isopropyl alcohol poisoning include flushing, headache, dizziness, nervous system depression, nausea, vomiting, anesthesia, and coma. Use in well-ventilated areas and use protective gloves while using. Poisoning can occur from ingestion, inhalation, or absorption.

Isopropyl alcohol acts as depressing thing. Its metabolite, acetone, is a depressant in its own right. Around 15 g of isopropyl alcohol can have a toxic effect on a 70 kg human if left untreated. However, it is not nearly as toxic as methanol or ethylene glycol. Isopropyl alcohol does not cause any gap (in which as lowered blood serum pH causes depletion of an anion) as do ethanol and methanol. Isopropyl alcohol does, however, produce an osmosis difference between the calculated and measured osmosis difference of serum, as do the other alcohols.

Overdoses may cause a fruity odor in the breath as a result of its metabolism to acetone, which is not further metabolized. By a deep consideration of the above mentioned facts about formaldehyde it can be clearly said that it is poisonous.
