(organic compound) A compound most often formed by the condensation of an alcohol and an acid, with elimination of water, which contains the functional group carbon-oxygen double bond (i.e., carbonyl) joined via carbon to another oxygen atom. Ether A volatile, highly flammable liquid, C4H10...

Stereolithography systems for conventional manufacturing applications have, as mentioned in an earlier section of this chapter, primarily used reactive acrylate/methacrylate, epoxide, or vinyl ether-based resins, or some hybrid composition thereof [5]. As stereolithographic fabrication technology expands to...
The focal point of this lesson will be on a specific class of organic compounds called aliphatic esters. Our primary points of discussion will...
Lipids were extracted using a modified methyl tert-butyl ether (MTBE, HPLC grade; Fischer Scientific, Massachusetts, USA) method as described previously50,51. Brain tissue (10 mg) was homogenized using a bead homogenizer (FastPrep-24, MP Bio, Sydney, Australia) at 6 m/s for 40 s, using...
The organic phase was extracted by addition of diethyl ether, then washed three times with saturated aqueous NaHCO3, separated, and dried over anhydrous MgSO4. The product was isolated by silica gel chromatography using a mixture of hexane and diethyl ether (9:1). Concentration under reduced ...
The ether bond is extremely stable. The oxirane method can also be used to fix hydroxylic components, such as alcohols and carbohydrates, to cross-linked agarose. Also thiols may be attached to agar gels by oxirane-agarose. The old and new methods of immobilization and their use for the ...
Interestingly, in imidazoline 1c (bearing an isopropyl group at the stereogenic center) reaction with benzaldehyde, the corresponding silyl ether 2c was obtained in higher yield (80%) and greater diastereomeric excess (de 95%) than other products. Using alkyl aldehyde for the reaction, the ...
The term "ester" was coined by the German chemist Leopold Gmelin in 1848. It is likely the term was a contraction of the German word "essigäther," which means "acetic ether." Examples of Esters Ethyl acetate (ethyl ethanoate) is an ester. The hydrogen on the carboxyl group ofacetic ...
