- W5969594 abstract "Hexenuronic acid (HexA) is formed during kraft pulping by the conversion of 4-O-methyl-glucuronic acid groups in strong alkali conditions. HexA can be removed from the pulp by including an acid hydrolysis (A) stage in the bleaching sequence. Despite a significant body of work in this area, very little research has been carried out to examine HexA in pulps produced from South African-grown tree species under the conditions of the local pulp and paper industry. The objective of this paper, which is part of a broader study, was to determine the optimum conditions in the A-stage that resulted in maximum removal of HexA, but with minimum impact on the physical and chemical properties of the pulp after bleaching. For this purpose, oxygen delignified pulps produced from a Eucalyptus hybrid clone, E. grandis x E. urophylla, were subjected to acid hydrolysis at varied temperature and reaction times. The pH was kept constant at 3.5 for all experiments. The results showed that the A-stage was efficient in the removal of HexA; acid hydrolysis carried out at 125°C-180min removed as much as 98% of the HexA, resulting in a kappa number reduction of approximately 6 units." @default.
