Synthesis of galactomannan sulfates

The experimental conditions for the sulfation of legume galactomannans were found, which allow for the obtainment of polysaccharides with a high degree of substitution. Sulfate esters of four galactomannans of different composition (galactose content, 16.4-47.5%) were synthesized using the SO^sub 3^...

Summary:The experimental conditions for the sulfation of legume galactomannans were found, which allow for the obtainment of polysaccharides with a high degree of substitution. Sulfate esters of four galactomannans of different composition (galactose content, 16.4-47.5%) were synthesized using the SO^sub 3^-pyridine complex in dimethylformamide as a sulfating agent. The degree of substitution was as high as 1.4-1.8; it did not correlate with the content of galactose in the polysaccharides. It was found that the degree of sulfation depended on the reaction temperature in the range of 19-60°C.[PUBLICATION ABSTRACT]
