The relationship of the dimer content of rosin determined by gas chromatography to crystallization time
The resin acid dimer content of rosin influences the crystallization time, as determined with the Burrell‐Castor Gelometer. A gas chromatographic packing prepared by treatment of Chromosorb W with dimethyldichlorosilane and trimethylchlorosilane resolved the methyl esters of rosin dimers into 15 com...

| Zusammenfassung: | The resin acid dimer content of rosin influences the crystallization time, as determined with the Burrell‐Castor Gelometer. A gas chromatographic packing prepared by treatment of Chromosorb W with dimethyldichlorosilane and trimethylchlorosilane resolved the methyl esters of rosin dimers into 15 components. A vacuum stripping method for assay of rosin dimer agrees with results obtained by quantitative gas chromatography. |
