The present disclosure provides a sound absorbing material. The sound absorbing material comprises MFI-structural-type zeolite. The MFI-structural-type zeolite comprises a framework, and the framework comprises SiO.sub.2 and AlO.sub.3, and the mass ratio of Si to Al in the framework is less than 200 and not less than 50. The present disclosure also provides a speaker box applying the sound absorbing material. The sound absorbing material provided by the present disclosure and the speaker box using the sound absorbing material can further improve the performance of the speaker box, reduce the failure of zeolite and improve the performance stability of the speaker box.

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.

The present invention relates to a molecular sieve, particularly to an ultra-macroporous molecular sieve. The present invention also relates to a process for the preparation of the molecular sieve and to its application as an adsorbent, a catalyst, or the like. The molecular sieve has a unique X-ray diffraction pattern and a unique crystal particle morphology. The molecular sieve can be produced by using a compound represented by the following formula (I), ##STR00001## wherein the definition of each group and value is the same as that provided in the specification, as an organic template. The molecular sieve is capable of adsorbing more/larger molecules, thereby exhibiting excellent adsorptive/catalytic properties.
