The present disclosure relates to amorphous and crystalline forms of (R)—N-(4-chlorophenyl)-2-((1S,4S)-4-(6-fluoro-quinolin-4-yl)cyclohexyl)propanamide and its salts/cocrystals, solvates, and/or hydrates, processes for their production, pharmaceutical compositions comprising them, and methods of treatment using them.

Disclosed are an organic proton-type ionic liquid, a film with a two-dimensional perovskite pure-phase quantum well structure, a preparation method and use thereof. The chemical formula of the organic proton-type alkylamine acetate ionic liquid is RNH.sub.3.sup.+—RCOO.sup.−, where R represents an alkyl group of C4-8 or a phenyl group, preferably, the chemical formula of the organic proton-type alkylamine acetate ionic liquid is CH.sub.3(CH.sub.2).sub.3NH.sub.3.sup.+—CH.sub.2COO.sup.−. The organic proton-type alkylamino acetate ionic liquid disclosed in the present disclosure can be used to prepare perovskite material, the prepared perovskite film thereby can form a pure-phase single quantum well, and the crystal grain size of the film can reach the level of micrometers or even millimeters.

Proposed is a two-pot-two-step simultaneous conversion system for carbon dioxide and a hydrocarbon containing at least one hydroxy group and a method thereof. The system integrates a process of producing a metal salt that is a dehydrogenated form of the hydrocarbon, hydrogen, and water by reacting a hydrocarbon containing at least one hydroxy group in the presence of water and a metal oxalate, and a process of converting carbon dioxide or carbon dioxide-derived carbonate into formate by hydrogenation, thereby increasing energy efficiency while maintaining a higher hydrocarbon conversion rate and a higher carbon dioxide conversion rate than the one-pot conversion system for hydrocarbon and carbon dioxide.

Methods for providing corrosion inhibition in conduits, containers, and wellbores penetrating subterranean formations are provided. In some embodiments, the methods comprise contacting a metal surface with a fluid comprising a corrosion inhibitor additive. In certain embodiments, the corrosion inhibitor additive comprises a compound comprising a hydrophobic cation moiety, one or more lipophilic tails, and a linking moiety.

Disclosed is a method for preparing salicylamine acetate. The method comprises the steps of: (1) carrying out amino protection on salicylaldehyde having a structure represented by formula 1 to obtain a compound having a structure represented by formula 2; and (2) carrying out acid hydrolysis to the compound having a structure represented by formula 2 and then reacting the acid-hydrolyzed compound with acetic acid to obtain salicylamine acetate.

A process, a system, and an apparatus are provided for converting a lower alkane to an alkene. Oxygen and the lower alkane are provided to an ODH reactor to convert at least a portion of the lower alkane to an alkene. An ODH stream comprising the alkene, an oxygenate, steam, and a carbon-based oxide is produced. The bulk of the oxygenate is removed from the ODH outlet stream by non-dilutive cooling, with residual oxygenate being removed using dilutive quenching with a carbonate. Subsequently, separation of the carbon-based oxide from the alkene is achieved using a caustic tower, which also produces spent caustic in the form of a carbonate, which is then used as the carbonate for dilutive quenching. Dilutive quenching using a carbonate allows conversion of the oxygenate to an acetate, which can then be used to simplify separation of the oxygenate from water.

Provide are an ionic liquid composition for a carbon dioxide separation membrane, a carbon dioxide separation membrane retaining the composition in voids, and a carbon dioxide concentration apparatus provided with the carbon dioxide separation membrane that can be used to separate carbon dioxide from high partial pressure to low partial pressure. The permeability of CO.sub.2 and CO.sub.2 selectivity ratio of the carbon dioxide separation membrane can be improved, and carbon dioxide from high partial pressure to a low partial pressure of 1 kPa or lower can be selectively separated and recycled by using an ionic liquid composition prepared by combining: an ionic liquid (I) that is an aminium having one or more primary or secondary amino groups and an ethylenediamine or propylenediamine backbone in the cation; and an ionic liquid (II) in which the cation has no primary or secondary amino group and the anion is an oxoacid anion.
