Patent number: 6610888Abstract: A method of reacting a solution comprising a mixture of chemical compounds which are in chemical equilibrium with one another with at least one further chemical compound (9) is provided. The method comprises the following steps: fractionation of the solution by means of a separation method to give at least two fractions (5, 6) which are enriched in different chemical compounds of the mixture; and reaction of a fraction (5) with the further chemical compound or compounds (9). The fractionation is advantageously carried out using a film evaporator (1). Unreacted fractions (6) can be recirculated via a residence time vessel (3) back to the fractionation step. The method is particularly suitable for reactions of an aqueous formaldehyde solution in which various components of the solution (formaldehyde, methylene glycol, polyoxymethylene glycols) react in different ways.Type: GrantFiled: May 31, 2000Date of Patent: August 26, 2003Assignee: BASF AktiengesellschaftInventors: Eckhard Ströfer, Stephan Scholl, Hans Hasse

Patent number: 6563006Abstract: Catalytic processes have been developed for direct ambient air oxidative conversion of hydrocarbons to aldehydes and unsaturated alcohols. Aliphatic hydrocarbons including methane, hexanes, octanes, decanes, gasoline, diesel fuel, oils, solvents and other organic compounds have been oxidized by this catalytic process. The catalysts are based on molecular strings of di-, tri- and/or poly-groups of transition metal complexes. Laboratory results have demonstrated [iron(II)]2, [manganese(II)]2 and related families of catalysts to be effective for ambient air direct oxidative conversion of hydrocarbons to products in high yields at room temperature and above, while [cobalt(II)]3 was effective for air oxidative conversion of methane to formaldehyde and for other gaseous hydrocarbons to their corresponding aldehydes at elevated temperatures.Type: GrantFiled: April 30, 2001Date of Patent: May 13, 2003Inventor: Melvin K.
