Abstract

PROCEDIMIENTO PARA DESACIFICAR MATERIALES CELULOSICOS, PROCEDIMIENTO PARA PREPARAR ALCOXIDOS METALICOS Y COMPOSICION QUE CONTIENE ESTOS COMPUESTOS. LA DESACIDIFICACION CONSISTE EN PONER EN CONTACTO MATERIAL CELULOSICO CON SOLUCIONES EN HIDROCARBUROS O HALOCARBUROS DE CIERTOS ALCOXIDOS METALICOS, ESPECIFICAMENTE ALCOXIALCOXIDOS DE MAGNESIO Y/O ZINC, EVENTUALMENTE TRATADOS CON DIOXIDO DE CARBONO PARA QUE TENGAN BAJA VISCOSIDAD. LA COMPOSICION COMPRENDE UNA MEZCLA DE COMPUESTOS DE FORMULAS: (RBS4O) Y M(OC(O)OCH(RBS2)CHSI2(OCH(RBS2)CHSI2)SINORBS3)SI2+.Y +.(RBS1OH)SIX*C Y*C (RBS4O)(O)CO) Y M(OCH(RBS2)CHSI2(OCH(RBS2)CHSI2)SINORBS3)SI2+.Y +.(RBS1OH)SIX*C *C DONDE M ES MG, ZN O SUS MEZCLAS, N ES 1-20, RBS3 Y RBS4 SON GRUPOS HIDROCARBILO, RBS2 ES HIDROGENO O METILO, RBS1 ES IGUAL O DIFERENTE DE RBS4 Y/O RBS3O (CHSI2CH(RSI2)OSINCHSI2CH(RBS2), Y VALE 0,01-1 Y X 0
