1,4-Dimethoxybenzene Chemical Properties,Uses,Production

Chemical Properties

white crystals or powder

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.

Occurrence

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

Uses

Weathering agent in paints and plastics, fixative in perfumes, dyes, resin intermediate, cosmetics, especially suntan preparations, flavoring.

Uses

1,4-Dimethoxybenzene is used as Pharmaceutical Intermediate. It is used in some paints and as a diazo dye. It is also used in perfumes and flavors in order to its floral odor. In addition, it is used on greasy skin, and with sulfur to treat acne, or as a dandruff treatment.

Preparation

By methylation of hydroquinone using dimethyl sulfate and alkali.

Synthesis Reference(s)

Journal of the American Chemical Society, 83, p. 1251, 1961 DOI: 10.1021/ja01466a056

General Description

Colorless crystals.

Air & Water Reactions

Slightly water soluble .

Reactivity Profile

1,4-Dimethoxybenzene 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.

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.]
