An impure propylene oxide feedstock contaminated with from about 50 to about 1000 ppm of methanol and from about 0 to about 1 wt. % of acetone is charged to the lower half of an extractive distillation column containing at least about 25 theoretical plates and an extractive distillation agent consisting essentially of a blend of acetone and water (acetone/water blend) containing about 20 to about 30 wt. % of acetone and, correspondingly, about 80 to about 70 wt. % of water is charged to the tower at a point 4 to 7 theoretical stages above the impure propylene oxide feed point; the extractive distillation agent being introduced into the extractive distillation column in the ratio of said feedstock to said extractive distillation agent of from about 5:1 to about 20:1, whereby an overhead distillate fraction is obtained consisting essentially of propylene oxide contaminated with not more than about 60 ppm of methanol, not more than about 0. 02 wt. % of acetone and not more than about 0. 3 wt. % of water.

A method of validating a request to access a target server in a computer network having an open, trusted database. The method begins when a request to access the target server is received at a host from which the scheme is supported. In response, a query is initiated to the trusted database to identify a technical, administrative or other contact person that may authorize the access request. In the Internet, the trusted database may be the WHOIS database that includes second level domain name information. A second query (e. g. , an e-mail) is then launched to the identified contact. The e-mail preferably includes a URL and a key. The URL identifies a response Web page interface that is accessible upon entry of the key. If the identified contact accesses the Web page interface, he or she may then authorize the access request, deny the access request, or indicate under what conditions the request may occur. The invention takes advantage of existing Internet infrastructure and methods to provide a robust lightweight authentication mechanism.

A scheduling method and system. The method includes receiving by a computing system first data and second data associated with a user. The first data comprises user identification associated, an activity selection for an activity, and first scheduling information. The second data comprises geographical preference data. The computing system determines facilities associated with the activity. The facilities are located within boundaries specified by the geographical preference data. The computing system generates tentative reservations for the user at each facility. The computing system presents the tentative reservations data to the user. The computing system receives verification data from the user. The computing system posts the tentative reservations data in a social networking environment. The computing system stores the tentative reservations data.

It has been discovered in accordance in accordance with the present invention that a tertiary butyl alcohol/ditertiary butyl peroxide azeotrope may be recovered from a product containing tertiary butyl alcohol and ditertiary butyl peroxide by distilling the tertiary butyl alcohol product to obtain an overhead fraction containing substantially all of the ditertiary butyl peroxide/tertiary butyl alcohol azeotrope and other contaminants. It has been further discovered in accordance with the present invention that the ditertiary butyl peroxide can be recovered from the distillate fraction by extraction with ethylene glycol (e. g. , in a countercurrent ethylene glycol extraction tower) to provide a ditertiary butyl peroxide product of any desired degree of purity.

Complexes made by reacting an ammonium-containing molybdenum compound with an alkylene glycol in the presence of water at an elevated temperature are described. Mild stripping of the water subsequent to complex formation is preferred. If some of the water is left in the complex, it may serve as an excellent olefin epoxidation catalyst. The ratio of moles of alkylene glycol to gram atoms of molybdenum in the complex forming reaction ranges from 7:1 to 20:1. Ethylene glycol and propylene glycol are the particularly preferred alkylene glycols.
