1,2-Dimethoxybenzene

1,2-디메톡시벤젠 C화학적 특성, 용도, 생산

화학적 성질

Colorless crystals or liquid. Soluble in alcohol and ether; slightly soluble in water.

출처

Reported present in asparagus (raw and cooked), bonito (dried), broccoli (cooked), cauliflower (cooked), cognac, endive, grape, Gruyere de Comte cheese, guava, leek (raw and heated), olive, peas, rhubarb, rice bran and vanilla extract.

용도

1,2-Dimethoxybenzene was used to investigate the electroantennogram response of vine weevil, Otiorhynchus sulcatus to plant volatiles.

정의

ChEBI: A dimethoxybenzene with the methoxy groups at ortho-positions.

제조 방법

Prepared by methylation of pyrocatechol.
1,2-Dimethoxybenzene can also be prepared from Catechol. The specific synthesis steps are as follows:
 Aqueous sodium hydroxide(40%,175 ml)is added dropwise during 3 hr at 18-22 to a well stirred mixture of catechol (50 g,0.45 mole),sodium hydrosulphite (20 g,0.115 mole),dimethyl sulphate (110 ml,146.63 g, 1.16 mole)and alcohol (150 ml).Ice (1 kg)is added to the reaction mixture and left overnight at room temperature.It is extracted with ether (2x 200 ml).The ether extract is washed with water,dried (anhydrous sodium sulphtate)and distilled.Veratrole is obtained as oil.Yield 52.75 g (84.1%).B.p.207°(1it.3b.p.207).

일반 설명

1,2-Dimethoxybenzene reacts with Li{N(SO₂CF₃)₂} to yield molecular crystal [Li{N(SO₂CF₃)₂}{C₆H₄(OCH₃)₂}₂] having solid-state lithium ion conductivity. It is a potential pollinator attractant of the nocturnal moth Hadena bicruris.

Toxicology

Data from 1,2-dimethoxybenzene and read-across analog 1,4-dimethoxybenzene (CAS # 150-78-7) show that 1,2-dimethoxybenzene is not expected to be genotoxic. Data show that there are no safety concerns for 1,2-dimethoxybenzene for skin sensitization under the current declared levels of use. The repeated dose, reproductive, and local respiratory toxicity endpoints were evaluated using the TTC for a Cramer Class I material, and the exposure to 1,2-dimethoxybenzene is below the TTC (0.03 mg/kg/day, 0.03 mg/kg/day, and 1.4 mg/day, respectively). The phototoxicity/photoallergenicity endpoints were evaluated based on UV spectra; 1,2-dimethoxybenzene is not expected to be phototoxic/photoallergenic. For the environmental endpoints, 1,2-dimethoxybenzene is not a PBT as per the IFRA Environmental Standards, and its risk quotients (i.e., PEC/PNEC) for the aquatic environment, based on its current volume of use in Europe and North America, are < 1

Purification Methods

Steam distil veratrole, then fractionally distil it from BaO, CaH2 or Na. Crystallise it from *benzene or low-boiling pet ether at 0o. Fractionally crystallise it from its melt. Store it over anhydrous Na2SO4. [Beilstein 6 IV 5564.]
