The result showed that the hydrolysates of all the pulps don't contain hexenuronic acid,but contain acid soluble lignin when acid hydrolysis was carried out under the conditions of pH 3.

In this paper, the formation and characteristic of hexenuronic acid (HexA) in kraft pulp and its influence on pulping and bleaching were introduced, and the methods of removing HexA were also discussed.

Xylanase was used to treat pulp for the purpose of reducing the hexenuronic acid content.
