Beschreibung
1,3-Dimethoxybenzene, also known as dimethyl resorcinol or 3-methoxyanisole, belongs to the class of organic compounds known as dimethoxybenzenes. These organic aromatic compounds contain a monocyclic benzene moiety carrying two methoxy groups. 1,3-Dimethoxybenzene has been used in the synthesis of novel oxathiane spiroketal donors. It forms pi- and O-ylidic complexes with dichlorocarbene (CCl(2)).
Chemische Eigenschaften
m-Dimethoxybenzene has a very powerful sweet-earthy, intensely, nut-like aroma.
Occurrence
Reported found in Gruyere de Comte, blue cheeses, filberts and cognac
Verwenden
1,3-Dimethoxybenzene is used for the preparation of oxathiane spiroketal donors. It is also used for the formation of pi- and O-ylidic complexes with dichlorocarbene. Further, it acts as a flavoring agent.
Vorbereitung Methode
1,3-Dimethoxybenzene can be produced 1) by Methylation of Resorcinol in weak aqueous alkali with Dimethylsulfate. 2) from Methanol and Resorcinol with Potassium hydrosuIfate or Sodium naphthalene sulfonate as dehydrating agent.
Definition
ChEBI: 1,3-Dimethoxybenzene is a member of methoxybenzenes.
Taste threshold values
Chemical, medicinal, spice, cooling root beer-like.

Allgemeine Beschreibung
1,3-Dimethoxybenzene can be used as a flavoring agent in the food industry. It is reported to be found in the volatiles of port wine and Roquefort cheese.
läuterung methode
Extract it with aqueous NaOH, and water, then dry it. Fractionally distil it from BaO or Na. [Beilstein 6 IV 5663.]
