Abstract

"AUXILIAR DE DIGESTãO PARA UM MATERIAL DE LIGNO-CELULOSE; E MéTODO PARA A PRODUçãO DE UMA POLPA". Trata-se de um auxiliar de digestão para um material de ligno-celulose, que compreende um tensoativo não-iónico (A) compreendendo um ou mais compostos representados pela fórmula geral (1): R^ 1^-O- 1 (C~ 2~H~ 4~O)~ m~/ (A^ 1^O)~ n~]-H em que R^ 1^ é um grupo alquila ramificado contendo de 4-24 átomos de carbono; m é um número inteiro de pelo menos 1, tendo uma média de 4-20; A^ 1^ é um grupo alquileno contendo e ou 4 átomos de carbono; e n é 0 ou um número inteiro de pelo menos 1, tendo uma média de 0-15; em que (C~ 2~H~ 4~O) e (A^ 1^O) , no caso da média de n ser 1-15, são ligados de forma aleatória ou em blocos."DIGESTION AID FOR A LIGNO-CELLULOSE MATERIAL; AND METHOD FOR THE PRODUCTION OF A PULP". It is a digestion aid for a ligno-cellulose material, which comprises a nonionic surfactant (A) comprising one or more compounds represented by the general formula (1): R ^ 1 ^ -O- 1 (C ~ 2 ~ H ~ 4 ~ O) ~ m ~ / (A ^ 1 ^ O) ~ n ~] -H wherein R ^ 1 ^ is a branched alkyl group containing 4-24 carbon atoms; m is an integer of at least 1, averaging 4-20; A ^ 1 ^ is an alkylene group containing e or 4 carbon atoms; and n is 0 or an integer of at least 1, averaging 0-15; where (C ~ 2 ~ H ~ 4 ~ O) and (A ^ 1 ^ O), in the case of the mean of n being 1-15, are connected randomly or in blocks.
