Furan je organická aromatická heterocyklická sloučenina uhlíku, vodíku a kyslíku. Je to bezbarvá, vysoce těkavá kapalina vonící podobně jako chloroform, je toxický a může být karcinogenní. Katalytickou hydrogenací furanu za účasti katalyzátoru palladia vzniká tetrahydrofuran. Jeho nejčastější použití je v plastech.
The analysis highlights Reakce, Syntéza and Fyzikální, chemické a biologické vlastnosti as prominent areas in the source structure around Furan.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
High-confidence facts extracted from structured source data. Use them as anchors for further research.
Browse the complete topic structure, not only the most central items. Less prominent entities and concepts can reveal missing angles, specialized context and useful research gaps. Each item opens a new analysis centered on that subject.
