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.

There is disclosed a novel monohydrate salt form of denatonium acetate. More particularly, the novel salt form and crystalline hydrate form is useful for the treatment and prevention of diseases and conditions, such as metabolic syndrome, obesity, NASH, glycemic control/diabetes, and IBD (intestinal bowel disease).

A method for producing an actinic ray-sensitive or radiation-sensitive resin composition, the method including passing a solution including an acid compound having a pKa of 2.0 or more through a column packed with an ion-exchange resin, producing an onium salt by using the acid compound having been passed through the column, and mixing together the onium salt and a resin that undergoes an increase in polarity due to action of acid.

A benzodiazepine compound represented by formula I, or a salt thereof has an intravenous sedative anesthesia effect. The recovery quality of the compound is significantly improved compared with remimazolam in rat and mouse caudal venous anesthesia models. During anesthetization, the compound has a rapid onset, a short duration, a quick recovery and a good tolerance, can be used for anesthesia induction, anesthesia maintenance and day surgery anesthesia.

The disclosure relates to oral formulations for gastric delivery of a pharmaceutically acceptable salt of a phenyl pyrrole aminoguanidine compound.

The present disclosure discloses free form or base and salts of compound of formula (I). Said salts include adipate, benzenesulphonate, hydrobromide, fumarate, benzoate, methanesulfonate, L-malate, d-glyconate, sorbate, phosphate, sulfate, L-tartrate, p-methylbenzenesulphonate, citrate, hydrochloride, ethanesulfonate, 1-hydroxy-2-naphthoate, succinate, acetate, glutarate or L-pyroglutamate. The present disclosure also discloses the crystals of free form and above salts.

Provided in the present invention are a salt of an arylaminopurine derivative represented by Formula (2), a preparation method therefor and the use thereof. The salt obtained in the present invention has good crystallinity and significantly improved solubility relative to that in the free form, and the preferred salt and crystal form have low hygroscopicity and can exist stably. Therefore, compared with the free form of arylaminopurine derivatives or other salts, it is easier to prepare same into a medicine.
