Abstract

Peracetic acid is being used to a limited extent as a bleaching agent for newsprint (1), and to a lesser extent, as a pulping agent, at least at the laboratory level (2). Haas, Schoch, and Ströle (3) report that peracetic acid is an excellent reagent for the preparation of holocellulose from wood. Ogait (4) also found that bleached cellulose could be obtained in 60 to 65% yield from wood and straw by the reaction of peracetic acid at 60 to 80°C. Haney, Martin and Sherk (5), and Poljac (6) have patented methods of oxidizing lignin in wood by peracetic acid. The high yields often obtained in bleaching, and excellent physical properties that it gives the sheet, make peracetic acid a very promising method, but high cost and instability have limited the extent of its use. Also, Baily and Dence (7) found peracetic acid inferior to chlorine dioxide for bleaching, in contrast to an earlier, more optimistic report by Wayman, Anderson, and Rapson (8).
