Abstract: An alcohol such as methanol is reacted with carbon monoxide in a liquid reaction medium including a catalyst, an alkyl iodide such as methyl iodide, alkyl acetate such as methyl acetate in specified proportions, an additive, and an effective amount of water, where the additive increases an ionic character of the hydrogen iodide bond and the effective amount of water is sufficient to facilitate carboxylic acid release after carbonylation at the catalyst and to reduce anhydride formation. The present reaction system not only provides an acid product at water levels considerable below levels currently used, but also provides unexpected reaction rates and unexpected high catalyst stability.

Abstract: Information about emergency situations is securely collected and processed by an agency, such as the local police force. When the information is approved for distribution as an emergency alert of a particular type, the alert is transmitted to a server. The server in turn facilitates the distribution of information widely to the public, and on a locality by locality basis. The server may format the emergency alert message or information for a variety of devices and send the information to those devices to convey the information to the public. The devices may include, for example, wireless devices, such as cell phones, personal digital assistants or any other type of wireless device; computers; electronic road signs; EAS equipment; computers and webpages; and any other type of output device.
