Chemical: Cyclobutanecarboxylic acid
Status: Active Update: 28-05-2018 https://echa.europa.eu/registration-dossier/-/registered-dossier/24735
Cyclobutanecarboxylic acid: Does not have an individual approval but may be used under an appropriate group standard
UsesCyclobutanecarboxylic acid is used in water treatment, row materials for sodium fluosilicate potassium fluosilicateammonium fluosilicatecopper fluosilicatebarium fluosilicate and other fluosilicates and silicic tetrafluoride. It is also used in refining lead of electrolysis, as mordant and in the treatment of metal surface.
PreparationCyclobutanecarboxylic acid synthesis: Put 1,1-Cyclobutanedicarboxylic acid into a distillation device for heating, decarboxylate at about 160°C to release carbon dioxide, then heat for distillation, collect 189-195°C fractions as crude product, and re-distill to obtain the finished product cyclobutanecarboxylic acid. Yield 86%-91%.
