Ni forskjellige prøver av n-butanol, fremstilt ved hydrering av krotonaldehyd, Nine different samples of n-butanol, prepared by the hydration of crotonaldehyde,
ble hver destillert i en fraksjoneringsdestillasjonskolonne for å fjerne ved overløp en fraksjon inneholdende acetaldehyd, n-butyraldehyd, vann og andre forbindelser som er til stede som har kokepunkter som were each distilled in a fractionating distillation column to remove at overflow a fraction containing acetaldehyde, n-butyraldehyde, water and other compounds present having boiling points which
er lavere enn kokepunktet for n-butanol. N-butanolet som ble tilbake, ble blandet is lower than the boiling point of n-butanol. The n-butanol that remained was mixed
med en mengde monoetanolamin som vist i tabellen, og ble destillert i en fraksjonert destillasjonskolonne som ble operert ved i det vesentlige atmosfærisk trykk. Renset n-butanol ble oppsamlet som destillat. with an amount of monoethanolamine as shown in the table, and was distilled in a fractional distillation column operated at substantially atmospheric pressure. Purified n-butanol was collected as distillate.
Fargene som ble utviklet av n-butanol The colors that were developed by n-butanol
som ble fremstilt på denne måte, etter behandling med svovelsyre som beskrevet ovenfor, sammen med mengden av krotonaldehyd og total karbonyl til stede, er angitt i følgende tabell. which was thus prepared, after treatment with sulfuric acid as described above, together with the amount of crotonaldehyde and total carbonyl present, are given in the following table.
