The synthesis of galactoglucomannan sulfates using a sulfamic acid/urea mixture in 1,4-dioxane was studied for the first time. The effect of the galactoglucomannan sulfation time and temperature on the sulfur content in the galactoglucomannan sulfates was investigated. The introduction of sulfate groups into the galactoglucomannan structure was confirmed by the elemental analysis and Fourier transform infrared spectroscopy. The initial and sulfated galactoglucomannans were identified by X-ray diffraction, electron microscopy, and gel permeation chromatography. The thermal analysis has shown that sulfated galactoglucomannan, after the endothermic peak related to the moisture removal, yields a pronounced high-intensity exothermic peak with a maximum at 216 °C, and above 230 °C, the heat absorption effect (endothermic peak) characteristic of decomposition of the parent substance in the range of 230–335 °C is observed. According to the scanning electron microscopy data, the initial galactoglucomannan consists of irregular asymmetric particles with an average size from 400 to 900 µm, and the sulfated galactoglucomannan ammonium salt consists of particles 200–500 µm in size with different shapes. It was shown by gel permeation chromatography that, after the sulfation process, the main galactoglucomannan peak shifts toward higher molecular masses (from 24 to 26 kDa).

首次研究了在1，4-二恶烷中使用氨基磺酸/脲混合物合成半乳葡甘露聚糖硫酸盐的方法。研究了半乳葡甘露聚糖硫酸化时间和温度对半乳葡甘露聚糖硫酸盐中硫含量的影响。通过元素分析和傅里叶变换红外光谱证实了硫酸根基团引入半乳葡甘露聚糖结构中。通过X射线衍射，电子显微镜和凝胶渗透色谱法鉴定了初始的和硫酸化的半乳葡甘露聚糖。热分析表明，硫酸化的半乳葡甘露聚糖在与水分去除相关的吸热峰之后，会产生明显的高强度放热峰，最高峰出现在216°C和230°C以上，观察到母体物质在230–335°C范围内分解时的吸热效果（吸热峰）特征。根据扫描电子显微镜数据，最初的半乳葡甘露聚糖由不规则的不对称颗粒组成，平均大小为400至900 µm，硫酸化的半乳葡甘露聚糖铵盐由大小为200–500 µm的不同形状的颗粒组成。凝胶渗透色谱法表明，在硫酸化过程之后，主要的半乳葡甘露聚糖峰向更高的分子量（从24至26 kDa）移动。硫酸化的半乳葡甘露聚糖铵盐由200-500 µm大小的颗粒组成，形状各异。凝胶渗透色谱法表明，在硫酸化过程之后，主要的半乳葡甘露聚糖峰向更高的分子量（从24至26 kDa）移动。硫酸化的半乳葡甘露聚糖铵盐由200-500 µm大小的颗粒组成，形状各异。凝胶渗透色谱法表明，在硫酸化过程之后，主要的半乳葡甘露聚糖峰向更高的分子量（从24至26 kDa）移动。
