Uses

Used in the Petroleum Industry:
2,2'-[oxybis(ethane-2,1-diyloxy)]bis[2-methylpropane] is used as an oxygenate additive for gasoline to improve its octane rating and reduce emissions. The addition of TAME enhances the performance and environmental characteristics of gasoline, making it a valuable component in the petroleum industry.
Used in Emission Reduction:
2,2'-[oxybis(ethane-2,1-diyloxy)]bis[2-methylpropane] is used as an emission reduction agent in gasoline. By increasing the oxygen content in the fuel, TAME helps to improve combustion efficiency, leading to a reduction in harmful emissions such as carbon monoxide, nitrogen oxides, and hydrocarbons.
Used in Fuel Performance Enhancement:
2,2'-[oxybis(ethane-2,1-diyloxy)]bis[2-methylpropane] is used as a fuel performance enhancer in gasoline. The addition of TAME increases the octane rating of the fuel, which helps to prevent engine knocking and improve overall engine performance. This makes TAME an essential component in the formulation of high-performance gasoline blends.

Diastereoselective synthesis, structure and reactivity studies of ferrocenyloxazoline gold(i) and gold(II) complexes

In the last few decades, gold complexes have demonstrated huge potential for soft Lewis acid catalysis. Despite the intensive research on Au complexes and planar chiral metallacycles, enantiopure ferrocenylgold complexes have-surprisingly-not been reported until the studies presented in this article. Herein, we report the asymmetric synthesis of planar chiral ferrocenyl Au(i) complexes. These dinuclear species form helically chiral ten-membered (NCCCAu)2 rings stabilized by aurophilic interactions. In supramolecular solid state structures, linear, zigzag or helical Au(i) wires with regular Au?Au separations were observed. The dissolved dinuclear entities could be oxidized by Au(i) to unique ferrocenyl Au(ii) complexes featuring short Au(ii)-Au(ii) bonds, while the ferrocene core remained intact. However, our initial studies revealed the issue of configurational lability of the ferrocenyl Au(ii) complexes in terms of the element of planar chirality in the presence of the gold source, (Me2S)AuCl. This was successfully addressed by a systematic study implementing permanent σ-donor ortho-protecting groups such as methyl and trimethylsilyl, which impede an epimerization event. Oxidation of the dinuclear Au(i) complexes was also accomplished by oxidative addition reactions with halogenated solvents, preferably CHCl3. Additional reactivity studies revealed that dinuclear Au(ii) dihalide complexes are also formed with reactive alkylhalides such as iodomethane, benzylbromide and benzyliodide. Interestingly, the whole spectral range of colors (violet, blue, green, yellow, and red) is covered by the title complexes depending on the Au oxidation state and the anionic ligands in the Au(ii) complexes. This appears to be quite unusual for ferrocenes, which typically adopt orange to red colors in a non-oxidized state.

Method for Producing Glycol Tert-Butyl Ether

A method is provided for producing glycol tert-butyl ether (GTBE). Diol and methyl tert-butyl ether (MTBE) are used. With the help of an acidic cationic exchange resin catalyst, GTBE are produced through transetherification. The present invention not only produces GTBE but also obtains highly-selective GTBE products. No by-products of glycol di-tert-butyl ether (GDtBE) and olefin are generated. The present invention effectively avoids the traditional complex procedure for separating GDtBE.

Synthesis of Ferrocene Oxazoline N,O ligands and Their Application in Asymmetric Ethyl- and Phenylzinc Additions to Aldehydes

The synthesis of a range of novel gem-disubstituted ferrocene-oxazoline ligands and their application in both the asymmetric ethyl- and phenylzinc additions to aldehydes is reported. These studies reveal that gem-disubstitution of i-Pr-containing ferrocene oxazoline ligands results in increased enantioselectivity compared to their unsubstituted counterparts. Utilizing zinc catalysis, these ligands provided a wide range of secondary alcohols in yields of up to 93% with ee's of up to >99%. An interesting crystal structure of a ferrocene oxide-lithium tetramer showing lithium-nitrogen coordination in the solid state is also presented.

Manipulating the diastereoselectivity of ortholithiation in planar chiral ferrocenes

The sense of asymmetric ortholithiation directed by a chiral oxazoline may be inverted simply by the choice of achiral ligand. Comparison of results with a number of ferrocenyl oxazoline derivatives suggests that lithiation takes place by coordination to the oxazoline nitrogen irrespective of the ligand used.

Method of Producing Diethylene-Glycol Tert-Butyl Ether Using Isobutylene and Diethylene Glycol

Usually an analysis of fuel displacement accident is required before operating a reactor. In the present invention, fuel displacement accident is analyzed by linearly combining calculation results of single displacement layouts and a calculation result of a default placement layout. In this way, a number of displacement combinations to be analyzed can be reduced. And, thus, time for the analysis is saved and safety of the reactor core can be affirmed.
