“…In order to link this study to previous work, SAPO of the AFI framework type was synthesised by the established ionothermal method . The study was systematically extended to investigate the effect of various parameters and reaction conditions (Table S1 and S2) on the resulting morphology, framework type, Si/Al composition, micropore area and volume, as well as structural properties.…”

The first systematic study on the ionothermal synthesis of silicoaluminophosphates (SAPOs) was performed to study the influence of reaction time, Si/Al or F/Al ratios and changing ionic liquid (cation, anion and alkyl group). The resulting materials were characterised by XRD, liquid ( 1 H) and solid state ( 29 Si) NMR, TPDA, SEM images, Volhard titration, as well as thermogravimetric and nitrogen sorption analyses. 1-Butyl-3methylimidazolium bromide ([C 4 mim]Br) as both solvent and structure-directing agent (SDA) produced the AFI framework. It was found that the resulting Si/Al ratio of SAPO-AFI increases with an increase in initial Si/Al ratio but decreases with F/Al ratio in the reaction mixture. Different ionic liquids giving the same framework type have no effect on the silicon uptake. The formation of Si-islands is favoured at extended reaction times or higher silicon content. The framework type of SAPOs can be changed from AEL to AFI by changing either the alkyl chain from ethyl to butyl, substituting the C2-position of the cation with a methyl moiety, or altering the cation (imidazolium vs. pyridinium). The framework selectivity was altered from AFI to LTA by changing the anion (of [C 4 py]Br to Cl À ), and to CHA by 1-methylimidazole addition. The first successful ionothermal synthesis of the AFI, LTA and CHA framework types of SAPOs is presented, providing a more efficient method than the conventional hydrothermal synthesis.[a] Dr.

“…The extent of disproportionation of [BF 3 X] − and equilibrium constants for reaction R2 ( K 2 ) are listed in Table . Considering that the content of [Emim][BF 3 X] is ∼80% and that the majority of ILs mixtures exhibit close to ideal mixing behavior, it could be assumed that the formula [Emim][BF 3 X] could represent the synthesized ILs …”

A new series of complex anion ionic liquids (ILs) [Emim][BF 3 X] (X = CH 3 SO 3 , EtSO 4 , HSO 4 , Tosylate) were synthesized and characterized by nuclear magnetic resonance, elemental analysis, differential scanning calorimetry analysis, and thermogravimetry. The physicochemical properties of these ILs, such as density, viscosity, conductivity, and surface tension, were measured and correlated with thermodynamic and empirical equations in the temperature range of 293.15− 358.15 K under ambient conditions, and the thermal expansion coefficient, standard molar entropy, lattice potential energy, viscosity activation energy, surface enthalpy, and surface entropy were further calculated from experimental values. According to the temperature-dependent viscosity and conductivity, [Emim][BF 3 X] ILs follow the Walden rule, and they are classified as "good (or super) ionic liquids".
