oxygen delignified kraft pulp from eucalyptus (e. urophylla × e. grandis) was catalytically pretreated in aerobic condition using ammonium persulfate in present of catalists like cupric acetate and/or cobalt acetate in acetic acid-water solution, i. e. s2o82--cu2+, s2o82--co2+ and s2o82--(cu2++co2+). final bleached pulp after pretreatment with the three catalytic systems showed higher delignifi...

When studying some organic ammonium salts as potential solubilizers [1—4] we found that they possessed good surface-active properties as well as significant antimicrobial activity. The assumption of favourable relationship between the effect of the ammonium group and the properties of the alkanecarboxylic acid and of its esters, respectively, prompted us to prepare the title compounds and study...
