In this study, the catalytic role of silicate forsterite (Mg₂SiO₄) surfaces in the synthesis of iminoacetonitrile (IAN, HN=CH-CN) from the condensation of two hydrogen cyanide (HCN) molecules is investigated through quantum mechanical simulations. Using density functional theory calculations, the potential energy surfaces alongside the kinetics of various surface-mediated reactions leading to the formation of IAN are characterized. The effectiveness of forsterite as a catalyst is a delicate balance of the surface reactivity: on one side, the deprotonation of HCN is mandatory to trigger the dimerization; on the other side, the species should be weakly bound to the surface, thus allowing for their diffusion to meet with each other. The work reveals interesting counterintuitive results: the (120) and (101) forsterite surfaces (the less reactive ones) exhibit favorable catalytic properties for the reaction, in detriment to the (111) one (one of the most reactive).

To date, reactions of SO₄^•– with alkyl sulfates and sulfonates, which are common organosulfur compounds found in atmospheric aerosols and cloud droplets, are not well understood. Here, we employed a laser flash photolysis-long path absorption (LFP-LPA) technique to measure the temperature-dependent oxidation kinetics of organosulfur compounds initiated by SO₄^•– in the aqueous phase. These compounds included five alkyl sulfates, namely, methyl sulfate (MS), ethyl sulfate (ES), octyl sulfate (OS), decyl sulfate (DS), and dodecyl sulfate (SDS), as well as three sulfonates, namely, methanesulfonate (MSA), hydroxymethanesulfonate (HMS), and 2-hydroxyethylsulfonate (HES). Our kinetic data revealed that the second-order rate constants of these organosulfur compounds were in the range of 10³ to 10⁸ L mol^–1 s^–1 and exhibited a positive temperature-dependency across the range of 278 to 318 K. Upon oxidation, the hydrogen abstraction is likely the dominant pathway. Moreover, alkyl sulfates and sulfonates generally exhibit smaller reactivities compared to other organic compounds with the same carbon number, such as alcohols. This reduced reactivity could be explained by the strong electron-withdrawing nature of sulfur functional groups (i.e., −OSO₃^– in alkyl sulfates and −SO₃^– in sulfonates). Among the two sulfur functional groups, −SO₃^– shows a stronger deactivating effect than −OSO₃^–, likely due to the higher charge density of the former.

When water passes through a mixture of NaCl and KCl, the solid dissolves and the initial eluate contains NaCl:KCl in a 2.4:1 molar ratio, consistent with the invariant point of the NaCl–KCl–H₂O ternary system. The ratio of eluted NaCl:KCl remains constant until the supply of one of the salts in the solid phase is exhausted and the eluate transitions to a saturated solution of the remaining salt. If the initial mixture of salts contains &lt;2.4:1 NaCl:KCl, a pure solution of KCl will eventually elute from the system. Similar behavior extends to the weathering observed in NaCl–KCl–MgCl₂–CaCl₂–H₂O mixtures. For this quinary system, the eluate initially contains NaCl:KCl:MgCl₂:CaCl₂ in an approximate ratio of 1:1.6:4:4. CaCl₂ and MgCl₂ are depleted rapidly relative to NaCl and KCl, and once the calcium and magnesium are exhausted, the system returns to the behavior observed of a NaCl–KCl–H₂O ternary system.
