The present disclosure relates to a novel method for preparing high-purity gadobutrol. The present disclosure can be easily applied to a large scale production because purity of intermediate can be managed via simple and mild process and accordingly, high-purity or ultra high-purity gadobutrol that has higher purity than previous gadobutrol can be prepared in high yield therethrough.

A class of alkanol amine ligands reacted with bismuth carboxylates lends unique curability properties to isocyanate and polyols for production of polyurethane for CASE applications, including growing demand for polyurethane spray-foam. The amino-alcohol ligand, when associated with bismuth neodecanoate, offers improved moisture and solvent resistance during B-side (polyol) storage, cure rates analogous to tin-based curatives, and overall good final physical properties of the cured polyurethane.

The present patent application relates to new metal complexes having at least one N-aminoguanidinate ligand. The patent application further relates to the preparation of the new metal complexes and also to their use. The new metal complexes are especially suitable as precursors for the preparation of functional layers by means of gas-phase thin-film processes such as CVD, MO-CVD, MOVPE and ALD. Additionally, they are also suitable as catalysts for olefin hydroamination and for olefin polymerization.

Provided herein are the metalloborane compounds, MOF-metalloborane compositions, and hydrogen storage system used for high density hydrogen storage. The compounds and compositions may have the structure M2B6H6 or MOF-M2B6H6-dicarboxylic acid. Particularly the transition metal M may be titanium or scandium and the MOF may be MOF5. The hydrogen storage systems hydrogen absorbed to the metalloborane compounds or to the MOF-metalloborane compositions. Methods of storing hydrogen are provided comprising flowing or passing hydrogen gas for absorptive contact with the metalloborane compounds or to the MOF-metalloborane compositions. A method for calculating the hydrogen storage capacity of a metalloborane is provided in which random sampling of the thermodynamic states of a two-system model of hydrogen in the presence of a metal organic framework-metalloborane crystal structure is used to calculate probability of hydrogen absorption.
