Investigations on the chemical composition of precipitates formed in the synthesis of alkyd resins


Polimery 1988, No 3, 95


DOI: dx.doi.org/10.14314/polimery.1988.095

Summary

By the application of various analytical techniques such as emission spectral analysis, titrimetric methods, complexometry, spectrophotometry and elemental analysis, the composition of precipitates formed in the process of alkyd resins synthesis and disturbing their manufacturing process has been established. It has been found that these precipitates are composed of a mixture of phthalates of various metals (with a distinct predominance of calcium phthalate) formed in the reaction o f phthalic acid (after hydrolysis of phthalic anhydride) with ions of metals contained in the reaction substrates.
