In organic chemistry, an acetal is a functional group with the connectivity R2C (OR')2. Here, the R groups can be organic fragments (a carbon atom, with arbitrary other atoms attached to that) or hydrogen, while the R' groups must be organic fragments not hydrogen.

2010年5月28日 · An acetal (sometimes called a ketal if originating from a ketone) contains a carbon with two single bonds to OR groups. Hydrates and hemiacetals are in equilibrium with their respective aldehydes and ketones.

Acetals are geminal-diether derivatives of aldehydes or ketones, formed by reaction with two equivalents (or an excess amount) of an alcohol and elimination of water. Ketone derivatives of this kind were once called ketals, but modern usage has dropped that term.

Acetal (polyoxymethylene or POM) is a high strength, low friction engineering plastic that has excellent wear properties in both wet and dry environments. Acetal is chemically resistant to hydrocarbons, solvents, and neutral chemicals. Easy to machine, acetal makes an outstanding choice for applications that require complex, tight tolerances.

2022年2月3日 · Acetal is a food-safe material that is used to make food processing equipment and kitchen appliances. A few grades of Acetal have been authorized by the FDA for use in the food sector. Therefore, it is consistently safe for most uses in the food and service industries.

What is Acetal? “An acetal is an organic molecule where two separate oxygen atoms are single bonded to a central carbon atom.” Two distinct oxygen atoms are singly linked to a central carbon atom in an acetal, which is an organic molecule. R 2 C(OR’) 2 is the general structure of acetals.

Acetal has been identified in drinking water, ground water, surface water, advanced treatment water, and in leachate samples. It has also been detected in orange essences, as a volatile component of pork, beef, and cognac, and in human breath samples.

2019年10月3日 · An acetal is an organic molecule where two separate oxygen atoms are single bonded to a central carbon atom. Acetals have the general structure of R 2 C(OR') 2 . An older definition of acetal had one at least one R group as a derivative of an aldehyde where R = H, but an acetal can contain derivatives of ketones where neither R group is a ...

2022年7月20日 · Now, let's consider acetal formation in a biochemical context. A very important example of the acetal/ketal group in biochemistry is the glycosidic bonds which link individual sugar monomers to form polysaccharides (see section 1.3 for a quick review).

Chemically speaking, an acetal is a functional group where you have two -OR groups sitting on the same carbon. So, it might look like a di-ether of some sort, but it is not! We know that a distinctive feature of a functional group is its unique chemical properties.
