Most DIY enthusiasts know the solvent acetone as simply acetone. With the closer designation, most people diverge. But especially with the offer on the Internet is again and again of "technical acetone" the speech. What this is all about, we have summarized here for you.
What is acetone?
Acetone is an organic solution. It is the oxidation product of secondary alcohols. As you might imagine, it is possible that the acetone exists in different qualities. Technical acetone defines nothing other than a certain degree of purity. Overall, a distinction is made between different qualities of purity:
- crude (crudum)
- for synthesis
- pure (purum)
- pure (puriss, purissimum)
- for analysis (reagent grade, per analysis or pa)
The degree of purity according to the pharmacopoeia
The degree of purity changes from less pure (crude, crudum) to "p. a. "better. In addition, there are other clearly defined degrees of purity. These are defined in so-called pharmacopoeias. These are designated differently depending on the area of application:
- Pharmacopoea Europaea Ph. Eur.
- United States Pharmacopeia USP-NF
Theoretically, acetone can correspond to all stated degrees of purity. However, acetone is technically common, although acetone Ph. Eur. Acetone p. a. Is quite common. It depends mainly on the use and the requirements. Especially in chemical synthesis as in the production of acrylic acetone must of course have a clearly defined degree of purity.
Acetone technically quite sufficient techn For the "home use" of do-it-yourselfers or the everyday applications of most craftsmen, technical acetone should be sufficient. Often, acetone is also available as acetone 99 percent and chemically pure.
Costs of acetone according to degree of purity
The purer the acetone is, the more expensive it is in the production and thus also in the sale. Therefore, technical acetone is also completely economical for most applications. In particular, since not infrequently the acetone should be diluted anyway.
Tips & Tricks Acetone was discovered as early as 1606. In nature it occurs in raspberries in the form of raspberry acetone. The acetone gives the raspberries their typical smell. The presence in edible fruits, however, should not hide the fact that acetone is slightly toxic. Ac Although acetone is not carcinogenic, as often suspected, it can cause serious harm (inhalation, eye, swallowing). Acetone on the skin does not only dry out and embrittle. The acetone is so absorbed and gets into the blood; Doctors were able to detect acetone after skin contact in the blood and spinal cord.
