Abstract
"MéTODO PARA O ALVEJAMENTO DE POLPA DE PAPEL". Diversos tipos de polpa de papel são alvejados em duas etapas em pressão atmosférica e em uma temperatura de menos do que ou igual a 100<198>C. A primeira etapa é realizada por colocar a polpa em estado bruto em contato com uma mistura de ácido peracético e de ácido perfórmico. A segunda etapa é realizada através do tratamento da polpa alvejada obtida a partir da primeira etapa, com uma solução de hidróxido de sódio e de peróxido de hidrogênio. As polpas obtidas têm um valor de abrilhantamento elevado e um grau de polimerização próximo ao das polpas em estado bruto. O método é ecológico e não poluidor.
