[General Description]

Colorless crystals.
[Reactivity Profile]

1,4-DIMETHOXYBENZENE(150-78-7) is an ether. Ethers may react violently with strong oxidizing agents. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
[Air & Water Reactions]

Slightly water soluble .
[Chemical Properties]

Hydroquinone Dimethyl Ether occurs in hyacinth oil and has also been identified in tea. It is a white, crystalline solid (mp 57–58°C) with an intensely sweet, somewhat herbal, nut-like odor.
Hydroquinone dimethyl ether is prepared by etherification of hydroquinone and is used in soap perfumes.
[Chemical Properties]

p-Dimethoxybenzene has a bitter taste.
[Chemical Properties]

white crystals or powder
[Occurrence]

Reported found in hyacinth (Hyacinthus orientalis L.) essential oil, Rhodophyllus icterius, papaya, peppermint oil, green tea, cherimoya and cooked shrimp
[Definition]

ChEBI: 1,4-Dimethoxybenzene is a dimethoxybenzene.
[Preparation]

By methylation of hydroquinone using dimethyl sulfate and alkali.

Journal of the American Chemical Society, 83, p. 1251, 1961 DOI: 10.1021/ja01466a056
[Flammability and Explosibility]

Notclassified
[Purification Methods]

Steam distil 1,4-dimethoxybenzene, then crystallise it from hexane or *benzene, and from MeOH or EtOH, but these are wasteful due to high solubilities. Dry it under vacuum. It also sublimes under vacuum. [Beilstein 6 IV 5718.]
