An electrolyte and a method of making an electrolyte of the formula: Mg[Al(R).sub.4].sub.2, where R represents a compound selected from a deprotonated alcohol or thiol; an amine; or a mixture thereof. The method includes the steps of: combining a Mg(AlH.sub.4).sub.2 precursor with an alcohol, thiol or amine of the general formula R—H to create a reaction liquor containing Mg[Al(R).sub.4].sub.2; and washing the reaction liquor in an organic solvent.

The metal organic framework (MOF) MIL-100(Al) can be produced in a process in which aluminum nitrate and trimesic acid are brought to react with one another in an alcohol/water mixture under the action of NH.sub.3 and/or an NH.sub.3-releasing compound under mild conditions.

The present invention relates to low temperature process for preparing nanoparticles of porous crystalline Fe-, Al- or Ti-based MOF carboxylate materials with low polydispersity index, and uses thereof, particularly as catalyst support for carrying out heterogeneously catalyzed chemical reactions, or as gas storage/separation/purification material, or as matrix for encapsulating active principles (medicine, cosmetics).

The present disclosure provides novel methods of making aluminum complexes with utility for promoting epoxide carbonylation reactions. Methods include reacting neutral metal carbonyl compounds with alkylaluminum complexes.

Provided herein are metal-organic frameworks having a repeating core structure that generally includes a linker coordinated to a secondary building unit through O-metal-O bonds. The linkers create a framework with a plurality of pores, where a cobalt carbonyl moiety occupies at least a portion of the plurality of pores. Provided are also methods of making such metal-organic frameworks via a solvothermal reaction. The metal-organic frameworks are suitable for use in carbonylation reactions, such as carbonylation of epoxides. The metal-organic frameworks may be used for producing acrylic acid from ethylene oxide and carbon monoxide on an industrial scale. The production may involve various unit operations, including for example a beta-propiolactone production system configured to produce beta-propiolactone from ethylene oxide and carbon monoxide; a polypropiolactone production system configured to produce polypropiolactone from beta-propiolactone; and an acrylic acid production system configured to produce acrylic acid with a high purity by thermolysis of polypropiolactone.

Compositions comprising multivariate metal-organic frameworks and other single-linker metal-organic frameworks are used for containing and storing a gas or fluid or for water harvesting or water purification applications.
