20080319202 | FLUID STORAGE AND DISPENSING METHODS AND APPARATUS - A method and device for storing and dispensing a fluid includes providing a vessel configured for selective dispensing of the fluid therefrom. Provided within a vessel is a nanocomposite material comprising an imidazolium surfactant and an integral solvent that is essential to the formation of the nanocomposite material. The fluid is contacted with the nanocomposite material for take-up of the fluid by the polymerized nanocomposite material. The fluid is released from the nanocomposite material and dispensed from the vessel. | 12-25-2008 |
20090054659 | Process to Prepare Sulfonyl Chloride Derivatives - A novel process for the preparation of hydantoin sulfonyl chlorides of general formula (I) wherein R and n are as specified in the description, and certain novel intermediates thereto, are disclosed. | 02-26-2009 |
20090292126 | Ionic Liquids - The present invention relates to compositions of matter that are ionic liquids, the compositions comprising any of eleven cations combined with any of three fluorinated sulfonated anions.
