General Description
A liquid with a sharp odor. Less dense than water. Flash point between 0-73°F. Mildly toxic by ingestion and inhalation. Severely irritates the skin and eyes. Used to make other chemicals.
Reactivity Profile
1,1-DIMETHOXYETHANE(534-15-6) may react violently with strong oxidizing agents. Can act as a weak base to form salts with strong acids and addition complexes with Lewis acids. In other reactions, which typically involve the breaking of the carbon-oxygen bond, ethers are relatively inert.
Air & Water Reactions
Highly flammable. May form unstable peroxides when exposed to oxygen. These products can sometimes be observed as clear crystals deposited on containers or along the surface of the liquid. Slightly soluble in water.
Health Hazard
Inhalation or contact with material may irritate or burn skin and eyes. Fire may produce irritating, corrosive and/or toxic gases. Vapors may cause dizziness or suffocation. Runoff from fire control may cause pollution.
Fire Hazard
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.
Chemical Properties
1,1-Dimethoxybenzene has a sharp, sweet, alcohol, ether, green, new-mown-hay odor
Chemical Properties
clear colorless liquid
Occurrence
Reported found in raspberry, blackberry, strawberry, peas, fresh figs, hop oil, coffee, cognac, white wine
and tea.
Uses
Acetaldehyde dimethyl acetal may be used in the preparation of glucoside derivatives of steganol. It may be used as polymer solvent for the encapsulation of water-soluble model protein, bovine serum albumin into biodegradable poly(D,L-lactic acid.
Uses
1,1-Dimethoxyethane is used as a reagent in the synthesis of tricyclic and tetracyclic 1,5-benzodiazepine derivatives as nevirapine analogues.
Uses
As Mering's mixture which is 2 vol dimethylacetal and 1 vol chloroform.
Definition
ChEBI: 1,1-dimethoxyethane is an acetal that is dimethoxymethane substituted by a methyl group at position 1. It has a role as a flavouring agent and a plant metabolite. It is an acetal and a diether. It is functionally related to a dimethoxymethane.
Purification Methods
Distil the dimethyl acetal through a fractionating column and fraction boiling at 63.8o/751mm is collected. It forms an azeotrope with MeOH. Alternatively purify it as for acetal above. It has been purified by GLC. [Beilstein 1 IV 3103.]
