Dimethoxybenzene Usage And Synthesis

Chemical Properties	clear colorless to slightly brown liquid
Chemical Properties	m-Dimethoxybenzene has a very powerful sweet-earthy, intensely, nut-like aroma.
Occurrence	Reported found in Gruyere de Comte, blue cheeses, filberts and cognac
Uses	Organic intermediate, flavoring.
Uses	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.
Preparation	From resorcinol by methylation using dimethyl sulfate and alka
Taste threshold values	Chemical, medicinal, spice, cooling root beer-like.
Synthesis Reference(s)	The Journal of Organic Chemistry, 55, p. 991, 1990 DOI: 10.1021/jo00290a033
General Description	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.
Purification Methods	Extract it with aqueous NaOH, and water, then dry it. Fractionally distil it from BaO or Na. [Beilstein 6 IV 5663.]
