What is acetone

Acetone is an organic solution. It is the oxidation product of secondary alcohols. As you can imagine, it is possible that the acetone is available in different qualities. Technical acetone defines nothing more than a certain degree of purity. Overall, a distinction is made between different qualities of purity:

  • raw (crudum)
  • technically
  • for synthesis
  • pure (purum)
  • pure (puriss, purissimum)
  • for analysis (analytically pure, pro analysi or p. a.)

The degree of purity according to the pharmacopoeia

The degree of purity changes from less pure (raw, crudum) to “for analysis p. a. "better. In addition, there are other clearly defined degrees of purity. These are laid down in so-called pharmacopoeias. These are designated differently depending on the area of ​​application:

  • Pharmacopoeia Europaea Ph. Eur.
  • United States Pharmacopeia USP-NF

Theoretically, acetone can correspond to all specified degrees of purity. However, acetone is technically common, with acetone Ph. Eur. Or Acetone p. a. Is quite common. It mainly depends on the use and requirements. Especially in chemical syntheses such as the production of acrylic, the acetone must of course have a clearly defined degree of purity.

Acetone is mostly technically sufficient

Technical acetone should be completely sufficient for "home use" by do-it-yourselfers or everyday use by most craftsmen. Acetone is often offered as acetone 99 percent and chemically pure.

Acetone cost by degree of purity

The purer the acetone, the more expensive it is to manufacture and therefore also to be sold. Therefore, technical acetone is completely sufficient economically for most applications. Especially since it is not uncommon for the acetone to be diluted anyway.

Acetone was discovered as early as 1606. It occurs naturally in raspberries in the form of raspberry acetone. The acetone gives the raspberries their typical smell. However, its presence in edible fruits should not hide the fact that acetone is slightly toxic.

Although acetone is not carcinogenic, as is often assumed, it can lead to serious damage (when inhaled, in the eyes, when swallowed). Acetone on the skin does not only have a drying and embrittling effect. The acetone is absorbed in this way and gets into the blood; Doctors were able to detect acetone in the blood and spinal cord after skin contact.
