Abstract: An Electronic Commerce system enables corporate purchasers and suppliers to electronically transact for the purchase and supply of goods/services. The system includes three major hardware and software components: buyer, supplier and bank/administration. To enable suppliers to supply goods and services online and process electronic orders, several software components are used for operating a supplier processor server and a supplier catalog server. To enable corporate purchasers to purchase products and services online, preferably over the Internet, from suppliers, software is used for operating a customer server to which multiple users may log-on and access the supplier server. An Automated Clearing House (ACH) server may be used to interface with a bank's (ACH) systems.

Abstract: Disclosed is a process for the recovery of residual rhodium from tar obtained by submitting a rhodium-containing catalyst-tar solution to an extraction using methyl iodide and aqueous hydrogen iodide, thereby recovering catalyst values in the aqueous phase and tar containing residual rhodium in the methyl iodide phase. The residual rhodium-containing tar is submitted to an extraction using a water-immiscible, inert solvent for the tar and aqueous ammonia to obtain residual rhodium in the aqueous phase. The catalyst-tar solution employed is derived from a production system in which acetic anhydride is prepared by carbonylating methyl acetate in the presence of rhodium, lithium and methyl iodide.
