Ethers and Derivatives

2-Methoxyethanol, or methyl cellosolve, is an organic compound with formula C 3H 8O 2 that is used mainly as a solvent. It is a clear, colorless liquid with an ether-like odor. It is in a class of solvents known as glycol ethers which are notable for their ability to dissolve a variety of different types of chemical compounds and for their miscibility with water and other solvents. It can be formed by the nucleophilic attack of methanol on protonated oxirane followed by proton transfer: C 2H 5O+ + CH 3OH → C 3H 8O 2 + H+ 2-Methoxyethanol is used as a solvent for many different purposes such as varnishes, dyes, and resins. It is also used as an additive in airplane deicing solutions. In organometallic chemistry it is commonly used for the synthesis of Vaska's complex and related compounds such as carbonylchlorohydridotris(triphenylphosphine)ruthenium (II). During these reactions the alcohol acts as a source of hydride and carbon monoxide.2-Methoxyethanol is toxic to the bone marrow and testicles. Workers exposed to high levels are at risk for granulocytopenia, macrocytic anemia, oligospermia, and azoospermia.The methoxyethanol is converted by alcohol dehydrogenase into methoxyacetic acid which is the substance which causes the harmful effects. Both ethanol and acetate have a protecting effect. The methoxyacetate can enter the Krebs cycle where it forms methoxycitrate.

Diphenyl ether is widely used as a heat transfer agent and a dye carrier. It can be used alone or as a mixture with other materials. Because of its reactivity, It can also be used as a raw material or chemical intermediate to produce commercial products. Diphenyl ether is used in the production of: Diphenyl ether is employed as a processing aid in the production of polyesters. It acts as a chemical intermediate in the production of surface active agents and high temperature lubricants, fire retardants like polybrominated diphenyl ethers (PBDEs) and fragrance for detergents. Heat transfer media – like DOWTHERMTM fluids used for heating industrial processes Alkylated diphenyl oxides – used to make surfactants, greases and lubricants Halogenated diphenyl oxides – used in insecticides, wood preservatives, and flame retardants for appliance casings in consumer electronic products High temperature solvents Coatings Textile dye labeling Plastics – like ethylene-propylene-diene monomer (EPDM) rubber that is used for membrane roofing materials Diphenyl ether plays a vital role in the Ferrario reaction to produce phenoxathiin, which finds application in polyamide and polyimide production. Involving similar reactions, diphenyl ether is a significant side product in the high-pressure hydrolysis of chlorobenzene in the production of phenol. Diphenyl ether is found in alcoholic beverages. Diphenyl ether is present in muscat grapes, green tea, vanilla, lemon balm, buckwheat, potato chips and grilled beef. Diphenyl ether is a flavouring ingredient.

Used as a monomer of polyimide, a high temperature resistant polymer material, also used as a dye intermediate in the plastic industry, and also used as a fragrance for resin synthesis. Dye intermediates. Resin synthesis. 1. It is one of the important raw materials for high temperature resistant resins such as new special engineering plastics polyimide, polyetherimide, polyesterimide, polymaleimide, and polyaramid; 2. It is also synthetic 3,3',4,4'-Tetraaminodiphenyl ether raw material, the latter is the main monomer for preparing a series of aromatic heterocyclic heat-resistant polymer materials. 3. It is also used as a raw material and crosslinking agent for synthetic polymers such as high-performance heat-resistant epoxy resin and polyurethane. 4. At the same time, it is also used to replace carcinogenic benzidine to produce azo dyes, reactive dyes and perfumes. At present, using diaminodiphenyl ether as a raw material has developed direct dyes of different color levels such as scarlet, brilliant red, sand red, yellow brown, green, gray, blue, brilliant orange, black, etc., which can be used for silk, wool, cotton, The dyeing of hemp and other fabrics is superior to benzidine dyes in terms of color fastness and exhaustion rate.
