WebThe two major process steps of mercerization and etherification were originally carried out in separate reactors with a dry solids content of about 80 to 90%, and no organic solvent was used (Voss 1939). The original two-step dry process of mercerization and subsequent etherification has now been widely substituted by a one-step slurry process WebMay 11, 2024 · Etherification of 5-hydroxymethylfurfural (HMF) and ethanol to yield ethoxymethylfurfural (EMF) is an important reaction for producing diesel blendstocks from biomass resources. This aqueous-phase etherification reaction occurs with higher selectivity on H-BEA (95%) than on Amberlyst-15 (76%), H-FAU (64%), H-MFI (88%), …

In organic chemistry, ethers are a class of compounds that contain an ether group—an oxygen atom connected to two alkyl or aryl groups. They have the general formula R−O−R′, where R and R′ represent the alkyl or aryl groups. Ethers can again be classified into two varieties: if the alkyl or aryl groups are … See more Ethers feature bent C–O–C linkages. In dimethyl ether, the bond angle is 111° and C–O distances are 141 pm. The barrier to rotation about the C–O bonds is low. The bonding of oxygen in ethers, alcohols, and water is similar. In … See more The C-O bonds that comprise simple ethers are strong. They are unreactive toward all but the strongest bases. Although generally … See more • Ester • Ether lipid • Ether addiction • Ether (song) • History of general anesthesia • Inhalant See more In the IUPAC Nomenclature system, ethers are named using the general formula "alkoxyalkane", for example CH3–CH2–O–CH3 is methoxyethane. If the ether is part of … See more Ethers can be prepared by numerous routes. In general alkyl ethers form more readily than aryl ethers, with the later species often requiring metal catalysts.
