Translation of "Aromatizität" in English

Have you completed the learning unit Aromaticity: Aromatic or not?

The same rules regarding aromaticity in carbocycles also apply for heterocycles.

This residue is characterised by a large number of condensed rings and a high aromaticity.

In the method now published, the first step involves removing the aromaticity ("dearomatization").

In the early sixties, Heinz Staab began to focus on the question of benzenoid and annulenoid aromaticity.

These limits are regarded as kept, if the vulcanised rubber compounds do not exceed the limit of 0,35 % Bay protons as measured and calculated by ISO 21461 (Rubber vulcanised — Determination of aromaticity of oil in vulcanised rubber compounds).

These limits shall be regarded as kept, if the vulcanised rubber compounds do not exceed the limit of 0,35 % Bay protons as measured and calculated by ISO 21461 (Rubber vulcanised — Determination of aromaticity of oil in vulcanised rubber compounds).

The principle of the aromaticity of transition states defines which of the two modes of attack is being preferred.

Loss of aromaticity initially leads to a ketone (quinone) which spontaneously tautomerizes to the corresponding aromatic phenol.

This learning unit explains the topological method to determine the aromaticity of transition states according to Ewans, Dewar and Zimmermann.

By “aryl” is meant groups with aromaticity, including 5- and 6-membered aromatic single-ring groups, which may contain zero to four heteroatoms, and multi-cyclic systems with at least one aromatic ring.

For the purposes of the present invention, the term “quinoniod groups” is understood to mean carbon rings, more particularly 6-membered ring systems having conjugated double bonds but no aromaticity.

The result is reported in ° C. The lower the MMAP, the higher the aromaticity of the test substance.

The term “aryl” is understood to include groups with aromaticity, including multi-member aromatic single ring groups and multicyclic systems with at least one aromatic ring.

The humic acids based product HuminFeed® on base of highly oxidized lignite is characterized by its high fungicide property due to its high aromaticity.

Sorption is determined by steric effects, the number of nitro functional groups and the aromaticity of the explosive-typical compounds.

During oxidation of anthracene-9,10-diol to anthraquinone, the aromaticity of only the less resonance stabilized middle ring is lost.

According to Hückel's rule, an aromatic compound must have (4n + 2) ? electrons that form an uninterrupted ? electron cloud. In addition, it must be planar and cyclic. If the compound is not planar and cyclic then it is also not aromatic.

Principally, all three approaches assure the same results. The third method, applying the principle of aromaticity of transition states, is the simplest and most descriptive one.
