Abstract: A synthetic process of producing liquid tin(II) alkoxides for use as either catalysts in the synthesis of lactide or as initiators in the polymerization of cyclic ester monomers to yield biodegradable polyesters is described. The synthetic process employs anhydrous tin(II) chloride dissolved in n-heptane mixed with dry diethylamine. Alcohols, ROH, in which the R groups are n-C4H9, n-C6H13, and n-C8H17 are added to the reaction mixture and stirred for 12 hours. The reaction mixture is then filtered under nitrogen or argon before being evaporated to dryness to yield the three tin(II) alkoxides, namely: tin(II) n-butoxide, tin(II) n-hexoxide, and tin(II) n-octoxide. All three tin(II) alkoxides are viscous, dark yellow liquids which are highly soluble in most common organic solvents. Furthermore, they can all be stored under an inert atmosphere for long periods without any significant change in their reactivity and, therefore, in their effectiveness as catalysts/initiators.

Abstract: A method for accessing document data via a web service is disclosed which includes receiving a request from a client application. The request for document data to be retrieved from a repository managed by an IDARS/DOM application. The method also includes processing the request including creating and transmitting at least one access request to the IDARS/DOM application, and receiving document data in response to each transmitted access request. The method further includes formatting the document data received from the IDARS/DOM application. The method still further includes transmitting the formatted document data to the client application. Apparatus, systems and articles of manufacture for accessing document data via a web service are also disclosed.
