Investigation of the stability of azacrown complexes with some transition metal ions [PDF]
مجله علوم و فنون هستهای, 2020 The separation of metal ions from nuclear waste is an important issue in the nuclear industry. Cyclic chemical compounds including ether groups are called crown ethers. These compounds strongly bind to certain cations, forming complexes.

Experimental and modeling study of the autoignition of 1-hexene/iso-octane mixtures at low temperatures [PDF]
, 2005 Autoignition delay times have been measured in a rapid compression machine at Lille at temperatures after compression from 630 to 840 K, pressures from 8 to 14 bar, \Phi = 1 and for a iso octane/1 hexene mixture containing 82% iso-octane and 18% 1 hexene.

Probing the C-H Activation of Linear and Cyclic Ethers at (PNP)Ir [PDF]
, 2009 Interaction of the amido/bis(phosphine)-supported (PNP)Ir fragment with a series of linear and cyclic ethers is shown to afford, depending on substrate, products of α,α-dehydrogenation (carbenes), α,β-dehydrogenation (vinyl ethers), or decarbonylation ...

Synthesis and desulfurization-decarboxylation of cyclic thionocarbonates of glycerol 1-ethers
Journal of Lipid Research, 1969 A method is described for the synthesis of cyclic thionocarbonates of 1-O-alkyl glycerols in quantitative yield. These derivatives of glycerol ethers can be quantitated by UV absorbance, analyzed by gas-liquid chromatography, or quantitatively converted ...

Oxetanes: Recent Advances in Synthesis, Reactivity and Medicinal Chemistry [PDF]
, 2016 The 4-membered oxetane ring has been increasingly exploited for its behaviors, i.e. influence on physicochemical properties as a stable motif in medicinal chemistry, and propensity to undergo ring opening reactions as a synthetic intermediate.

A TGA/FTIR and Mass Spectral Study on the Thermal Degradation of Bisphenol A Polycarbonate [PDF]
, 2004 The thermal degradation of polycarbonate under nitrogen was studied using TGA/FTIR, GC/MS and LC/MS as a function of mass loss. The gases evolved during degradation were inspected by in situ FTIR and then the evolved products were collected and analysed ...
