Make Formic Acid

In this video we make formic acid from oxalic acid and glycerol. • • First we combine 100g of glycerol with 100g of oxalic acid in an Erlenmeyer. A distillation apparatus is assembled around the flask and the mixture is gently heated to 105-120 Celsius. I personally didn't have a thermometer so i simply raised the temperature of the hot plate by about one degree per minute until i saw refluxing in the flask. The flask was then covered in aluminum foil to retain heat and encourage distillation and decomposition. First the distillation slowed (after about 1 hour) and the bubbling eventually slowed (after about 3 hours). The mixture was then cooled an additional 100g of oxalic acid was added. The mixture was then heated again and distilled. This cycle of waiting for the bubbling to subside and then adding more oxalic acid was repeated for 2 additional times for a total of 4 additions (including the initial oxalic acid addition). After the bubbling subsided again 50mL of water was added and the mixture distilled one last time. • Fractional distillation was performed to obtain formic azeotrope at 106-108 degrees Celsius. Total yield was 122g. Assuming the concentration is 77% then the formic acid yield was 94g or about 64% of theoretical. • • Related videos: • Make Silver conductive ink: • Make Conductive Silver Ink (complex i... • • Donate to NurdRage! • Through Patreon (preferred): / nurdrage • Through Bitcoin: 1NurdRAge7PNR4ULrbrpcYvc9RC4LDp9pS • Glassware generously provided by http://www.alchemylabsupply.com/ • Use the discount code nurdrage for a 5% discount. • Social media links: • Twitter: / nurdrage • Facebook: / nurdrageyoutube • Instagram: / nurdrageyoutube • This video generously sponsored by my patrons: • Jon Stanovich • Michael Zappe • Emil Mikulic • Anthony Rodriguez • Alex S. • Lord Martin Hill • Matthew Brunette • Simon Bitdiddle • Cullen Purkis • Carl Potter • Goodwine • Martel DuVigneaud • Zane Bacon • Roger • Bryan Boettcher • Dror Kronstein • Michael Gregg • Robert Boll • Nick Kinnan • doug dysart • Daniel Astbury • The King of Homestyle • Stephen Stair • Bobby Nansel • Andrea Nall • Dom Vasta • Tyler Bushey • Michael • Syam Krishnan • Phillip Hutchings • Uocjat • Marius Klimantavičius • Jacob Gruber • Henry Wu • Antton Tapani • Jean-Marc Bélisle • Lunarchy • Mark Oberfield • Meagan McLay • Curt Fischer • Christian Ullrich • Leonard Marshall • Daniel McLaughlin • Evan Schuld • Mecha Chocobo • Jason King • David Gilmour • Dean Bailey • Matt Sieker • Ben Anderson • Jessica Porter • Chase Curtis • Connor Reed • Wolf Bennett • Christian Cooper • Pablo Soares • Samuel Pelzer • Wesley Gardner • Mark Rose • Py • Kremling • Brian Nietfeld • Leon Verrall • Feliksas • George Jefferies • Syniurge • evan • Applied Science • Yuli Talyansky • Micha Gorelick • Marcio Yukio Teruya • Timothy Vincent • Chris M Guerra • Collin B Douglas • Daniel L. • Michal Z • Florent Parent • Thor • Danny Chan • Miguel-Angel Gutierrez • Casey Kikendall • David Drueding • Kay Bærulfsen • Craig M. • Adrian Kleven • Mark Beeunas • David • Craig House • John Bonnin • Benjamin Nied • Jacob Rodriguez • Benedikt Müller • Evan • Robert Kennymore • Julian Nicolai • rjk • Thomas Phipps • Jordan Blackman • LFTRnow • SaltyBrains • Scott Blanchette • Martins Latvis • Andy Hims • l.h. riley • T.
