Determination of Polyols in Alkyd and Polyester Resins by Gas Liquid Chromatography

摘要

Polyols are one of the major components in alkyd and polyester resins and the physical characteristics of these resins are greatly influenced by the type of polyol present. The objective of this investigation was to develop a quantitative analytical procedure for dihydric alcohols which would be suitalbe for quality control. The procedure described in this report employs gas chromatography for the analysis of polyols liberated from resins by refluxing with butylamine. Qualitative and quantitative analysis for diols is accomplished by standardization with known polyol solutions. (Author)
