Question

What is the action of dilute hcl on acetaldehyde diethyl acetal?

Answer 1

Acetaldehyde (systematic name ethanal) is an organic chemical compound with the formula CH3CHO, sometimes abbreviated by chemists as MeCHO (Me = methyl). It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry. Acetaldehyde occurs naturally in coffee, bread, and ripe fruit,[11] and is produced by plants. It is also produced by the partial oxidation of ethanol by the liver enzyme alcohol dehydrogenase and is a contributing cause of hangover after alcoholconsumption. Pathways of exposure include air, water, land, or groundwater, as well as drink and smoke.[12] Consumption of disulfiram inhibits acetaldehyde dehydrogenase, the enzyme responsible for the metabolism of acetaldehyde, thereby causing it to build up in the body.

Acetaldehyde




Answer 2

The nature of the products obtained from reactions of acetaldehyde with  methanol have been investigated in neutral and acidic solutions by titration with  iodine and sodium bisulphite, ultraviolet absorption, and infrared spectroscopy.  In neutral and buffered solution the hemiacetal is the only important product; in  the presence of a high concentration of hydrogenions the acetal is produced nearly  quantitatively.

It is well known that the reaction between many aldehydes and alcohols  leads to the formation of acetals.
