Aldehydes, Ketones and Quinones

Acetone is a manufactured chemical that is also found naturally in the environment. It is a colorless liquid with a distinct smell and taste. It evaporates easily, is flammable, and dissolves in water. It is also called dimethyl ketone, 2-propanone, and beta-ketopropane. Acetone is used to make plastic, fibers, drugs, and other chemicals. It is also used to dissolve other substances. It occurs naturally in plants, trees, volcanic gases, forest fires, and as a product of the breakdown of body fat. It is present in vehicle exhaust, tobacco smoke, and landfill sites. Industrial processes contribute more acetone to the environment than natural processes.

Benzaldehyde, also known as benzoin aldehyde, is an organic compound formed after the hydrogen of benzene is replaced by aldehyde group. Benzaldehyde is the simplest and most commonly used aromatic aldehyde in industry. At room temperature, it is a colorless liquid with special almond smell. Benzaldehyde is a compound formed by the direct connection of aldehyde group and phenyl group. It was once called bitter almond oil because of its flavor similar to bitter almond. Benzaldehyde widely exists in the plant kingdom, especially in Rosaceae plants. It mainly exists in the form of glycosides in the stem bark, leaves or seeds of plants, such as amygdalin in almond, cherry, laurel leaves and peach kernel. Benzaldehyde naturally exists in almond oil, agastache oil, hyacinth oil, Ylang Ylang Ylang oil and other essential oils. Benzaldehyde is an important raw material for medicine, dyestuff, perfume and resin industry. It can also be used as solvent, plasticizer and low temperature lubricant. In the flavor industry, it is mainly used for the deployment of food flavors. It is used in flavoring and tobacco flavors. Although widely used as commercial food condiments and industrial solvents, benzyl alcohol is mainly used in the synthesis of a variety of other compounds ranging from pharmaceuticals to plastic additives. Benzyl alcohol is also an important intermediate product in the production of perfume, perfume and synthetic aniline dyes.

It can be used in paints and other coatings. It's also used for glue and as a cleaner.

Acrolein (IUPAC Name: 2-acrolein) is the simplest α,β- Unsaturated carbonyl compound, with chemical formula of C3H4O, is a colorless, transparent and malodorous liquid under normal circumstances, and its vapor has strong irritation and tear inducing properties. It is a very important synthetic intermediate in chemical industry. It is widely used in resin production and organic synthesis.

Cyclopentanone is a colorless and transparent oily liquid with a special ether and slightly peppermint like odor. It is insoluble in water, but soluble in ethanol, ether and acetone. It is narcotic at high concentration and can be prepared by oxidation of Cyclopentanol. Cyclopentanone is a kind of organic chemical raw material, which is also a raw material for medicine and perfume industry. It can be used to prepare new perfume methyl hydrojasmonate, as well as for rubber synthesis, biochemical research and insecticide. For example, cyclopentanone and valeraldehyde are used as raw materials to form amyl cyclopentanone through hydralic condensation and dehydration. Then, selective catalytic hydrogenation is used to produce amyl cyclopentanone. Amyl cyclopentanone has strong floral and fruity fragrance, and has jasmine fragrance. It can be used in the daily flavor formula, and its dosage can be less than 20%.
