Patent number: 7612233Abstract: The calculation of the above balance shows that the division of stream (5) into the streams (5a) and (5b) used here leads to the fact that in the neutralization stage no excess sodium formate is produced, so that any ejection can be omitted. Furthermore, the water content of the stream (14) comprising sodium formate recirculated to the first crystallization stage in this case can be set to a very low value.Type: GrantFiled: May 2, 2006Date of Patent: November 3, 2009Assignee: BASF SEInventors: Alexander Hauk, Stefan Gropp, Robert Lenz, Daniela Rieck, Jörg Heilek, Gerhard Laux

Publication number: 20090143618Abstract: A process is proposed for preparing acid formates in which a liquid stream I comprising formic acid and a liquid stream II comprising a metal formate are prepared, the liquid streams I and II are fed to a rectification column in such a manner that a higher or identical feed point to the rectification column is chosen for the liquid stream II than for the liquid stream I, the liquid streams I and II are mixed in the rectification column, with water being removed overhead from the rectification column and a bottoms stream comprising the acid formate is taken off from the rectification column, which comprises the bottoms stream being produced as melt comprising less than 0.5% by weight of water.Type: ApplicationFiled: November 5, 2004Publication date: June 4, 2009Applicant: BASF AKTIENGESELLSCHAFTInventors: Alexander Hauk, Jorn Karl, Jurgen Paschold, Stefan Gropp, Anna Valeska Lohmann, Robert Lenz, Thomas Letzelter, Robert Heinz
