text: formic acid is removed by distillation from the liquid stream comprising formic acid, water and tertiary amine (I) obtained from step (b) in a distillation apparatus at a temperature at the bottom of from 100 to 300° C. and a pressure of from 30 to 3000 hPa abs.
text: WO 2012/000,964 teaches a process for obtaining formic acid by thermal separation of a stream comprising formic acid and a tertiary amine, in which combining tertiary amine and a formic acid source produces a liquid stream comprising formic acid and a tertiary amine in a molar ratio of from 0.5 to 5, from 10 to 100% by weight of the secondary components comprised therein are separated off and formic acid is removed by distillation from the resulting liquid stream in a distillation apparatus at a temperature at the bottom of from 100 to 300° C. and a pressure of from 30 to 3000 hPa, and the bottom output from the distillation apparatus is separated into two liquid phases of which the upper liquid phase is enriched in tertiary amine and is recirculated to the formic acid source and the lower liquid phase is enriched in formic acid and is recirculated to removal of the secondary components and/or to the distillation apparatus.
