    • A method for preparing hydroxymethylfurfural, which includes: a) mixing and dissolving triose or its derivatives and solvent 1 to obtain the first reaction mixture; b) reacting the obtained first reaction mixture with Alkaline Catalyst 1 to condense into hexose; c) mixing and dissolving the resulting hexose and solvent 2 to obtain the second reaction mixture; d) adding acid catalyst 2 to the second reaction mixture, then heating the second reaction mixture at 80˜280° C. to form the third reaction mixture including hydroxymethylfurfural; e) obtaining the hydroxymethylfurfural separating by separating from the third mixture. The method is a new synthetic way for preparing 4-hydroxymethylfurfural and 5-hydroxymethylfurfural.
    • 一种制备羟甲基糠醛的方法,其包括:a)将丙糖或其衍生物和溶剂1混合并溶解得到第一反应混合物; b)将获得的第一反应混合物与碱性催化剂1反应,以冷凝成己糖; c)混合并溶解所得己糖和溶剂2以获得第二反应混合物; d)向第二反应混合物中加入酸催化剂2,然后在80-280℃下加热第二反应混合物以形成第三反应混合物,包括羟甲基糠醛; e)通过与第三混合物分离获得羟甲基糠醛分离。 该方法是制备4-羟甲基糠醛和5-羟甲基糠醛的新合成方法。
