Abstract:
A method for storing or separating acetylene is provided to store a large amount of acetylene safely even at low temperature or ambient temperature, and to produce high-purity acetylene gas by using a metal-formate porous crystal material. A storage method of acetylene includes a step of bringing acetylene or an acetylene-containing gas mixture into contact with a metal-formate porous crystal material represented by the following structural formula 1 to adsorb the acetylene. In the formula 1, each formate ion is bonded to three metal ion(M)s, each metal ion is bonded to six formate ions, a compositional ratio of the metal ion(M) and formate ion is 1:2, and the metal is Mg, Mn, Co, Zn, or Fe.
Abstract:
PURPOSE: A giant multimeric carbohydrate in which two or more multimeric carbohydrates are bonded to a single anchoring agent is provided to be used as a protein inhibitor. CONSTITUTION: A giant multimeric carbohydrate in which two more multimeric carbohydrate are bonded to a single anchoring agent is formed by covalent bond of one or more carbohydrate derivative with cucurbitruil derivative single molecule A1 or A2 of chemical formula 1. The carbohydrate derivative is monosaccharide, disaccharide, or polysaccharide. A protein inhibitor contains the giant multimeric carbohydrate. An anti-adherent of microorganism contains the giant multimeric carbohydrate.
