Изобретение относитс к способам защиты целлю; зосодержащих материалов- от поражени микроорганизмами и может быть использовано, например, с в целлюлозно-бумажной промьндленности.This invention relates to methods for protecting cella; zoosudozhaschimi materials from damage by microorganisms and can be used, for example, with a pulp and paper industry.
Известны способы обработки целлюлозосодержащих материалов салициланилидом и его натриевой солью 1.Known methods of processing cellulose-containing materials salicylanilide and its sodium salt 1.
Известен также способ консервации ,Q целлюлозосодержащих материалов, включающий обработку их динитрокислотой 2 .There is also known a method of preservation, Q cellulose-containing materials, including the processing of their dinitroacid 2.
Недостатком таких способов вл етс слаба защита от микроорганизмов при высоком расходе веществ. The disadvantage of such methods is weak protection against microorganisms with high consumption of substances.
Цель изобретени - повышение эффективности защиты от микробиологического поражени .The purpose of the invention is to increase the effectiveness of protection against microbiological damage.
Указанна цель достигаетс Тем, 20 что в качестве динитрокислоты используют с(.-галогендинитромасл ную кислоту в количестве 0,005-0,1% от веса абсолютно сухого материала.This goal is achieved by the fact that 20 as a dinitroacid is used with (. - halogen endinitric acid in an amount of 0.005-0.1% by weight of absolutely dry material.
В качестве ot-галогендинитромасл - 25 ной кислоты могут быть использованы 4-вром-4,4-динитромасл на кислота, 2-метил-4-бром-4,4-динитромасл на кислота и 4-хлор-4,4-динитромасл нгш кислота.4-bromo-4,4-dinitrobutyric acid, 2-methyl-4-bromo-4,4-dinitrobromic acid and 4-chloro-4,4-dinitrobutl ngsh can be used as ot-halohendinitro-butyric acid. acid.
Способ осуществл етс следующим образом.The method is carried out as follows.
Дл обработки 1000 г (вес абс.сух. целлюлозосодержаадего материала беретс 0,05 г 4-бром-4,4-динитромасл ной кислоты, раствор етс в 100 мл ацетона и полученным раствором производитс опрыскивание материала.For the treatment of 1000 g (the weight of the absolute dry cellulose content of the material is 0.05 g of 4-bromo-4,4-dinitrobasic acid, dissolved in 100 ml of acetone, and the resulting solution is sprayed.
Фунгицидна и бактерицидна активности соединений представлены в таблице.Fungicidal and bactericidal activity of the compounds are presented in the table.
