Cyclobutanecarboxylic acid Usage And Synthesis
- Chemical PropertiesCLEAR COLOURLESS TO SLIGHTLY AMBER LIQUID
- Synthesis Reference(s)The Journal of Organic Chemistry, 22, p. 1680, 1957 DOI: 10.1021/jo01363a041
- Purification MethodsDissolve 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.
