| | Cyclobutanecarboxylic acid Usage And Synthesis |
| Chemical Properties | CLEAR COLOURLESS TO SLIGHTLY AMBER LIQUID | | Uses | Cyclobutanecarboxylic 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. | | Preparation | Cyclobutanecarboxylic 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%. | | Synthesis Reference(s) | The Journal of Organic Chemistry, 22, p. 1680, 1957 DOI: 10.1021/jo01363a041 | | Purification Methods | Dissolve the acid in aqueous HCO 3 then acidify with HCl and extract it into Et2O, wash with H2O, dry (Na2SO4), concentrate to a small volume, then distil it through a glass helices packed column. The S-benzylisothiuronium salt has m 176o (from EtOH), the anilide has m 112.5-113o, and the p-toluide has m 123o.
