AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Imidazolium chlorides with one or two carboxylic acid substituent groups, 1-methyl-3-alkylcarboxylic acid imidazolium chloride, [Me{(CH2)(n)COOH}im]Cl (n=l, 3), and 1,3-dialkylcarboxylic acid imidazolium chloride, [{(CH2)(n)COOH}(2)im]Cl (n=1, 3), have bee ...
The reaction of catechol methylation by methanol in gas-phase over modified g-alumina was studied with the aim to correlate catalytic activity and selectivity to acid/base properties of the catalysts. Catalytic activity and selectivity towards guaiacol for ...
Novel chemical compounds of the general formula KA, in which K is a 5- or 6- membered heterocyclic ring having 1-3 hetereo atoms, which can be independently N, S, or 0 with the proviso that at least one of the hetereo atoms must be a quaternized n ...
Room temperature ionic liquids (RTILs), considered as "designers' solvents", are attracting a great attention because of their possibility to be tailored based on property requirements. The ionic liquids designed and synthesized for carrying out specified ...
A series of 'dual-functionalised' ionic liquids, comprising imidazolium cations with various functionalities and the nitrile functionalised anion CH3H(BF3)CH2CN have been prepared; some exhibit very low viscosities-a highly valuable property in many a ...
A series of imidazolium salts with the nitrile functional group attached to the alkyl side chain, viz. [C(n)CNmim][X] (where C(n)CNmim is the 1-alkylnitrile-3-methylimidazolium cation and C-n = (CH2)(n), n = 1-4; X = Cl, PF6, and BF4) and [C(3)CNdmim][X] ( ...
