Abstract
Official abstract text for this publication.
Adsorbent materials adsorb large quantities of inert permanent gases and maintain the initial pressure inside aerosol packages throughout the useful life of the packages, thus acting as propellants.
First claim
Opening claim text (preview).
What is claimed is: 1. An aerosol package comprising a bag, a can, and a valve; wherein the volume between said bag filled with product and said can is a propellant volume; wherein said propellant volume comprises an MOF and carbon dioxide; wherein said carbon dioxide is partly adsorbed in said MOF, forming an adsorption matrix with uptake constant K greater than about 0.015 g/g.psig at about 100 psig, and the remainder of said carbon dioxide is in equilibrium with said adsorbed carbon dioxide at a pressure; and wherein said pressure remains constant throughout the useful life of said aerosol package. 2. The method of claim 1 , wherein said MOF is MIL-101. 3. The method of claim 1 , wherein said MOF is MOF-177. 4. The method of claim 1 , wherein said pressure inside said aerosol package is about 100 psig.-10. 5. The method of claim 1 , wherein said aerosol package is selected from the group comprising a bag-in-bottle package and a bag-on-valve package. 6. The method of claim 5 , wherein said aerosol package is a bag-on-valve package; wherein said adsorbent material is MIL-101; and wherein said pressure is about 100 psig.
