Abstract

PREPARACION DE ALCOXILATOS DE FORMULA R1O(-CHR2-CHR2-O-)NH, DONDE R1 ES ALQUILO LINEAL O RAMIFICADO DE 6C, R2 ES H, METILO O ETILO Y N UN ENTERO DE 1 A 5. SE PREPARAN POR REACCION DE UN ALCOHOL ALIFATICO CON 4-6C, CON 1-5 MOLES DE OXIDO DE PROPILENO O BUTILENO O SUS MEZCLAS. LOS ALCOHOLES PUEDEN SER ALIFATICOS DE CADENA LINEAL O RAMIFICADA O ALICICLICOS DE 4-6C, LOS OXIDOS DE ALQUILENO PUEDEN SER: 1,2-OXIDO DE BUTILENO O 2,3-OXIDO DE BUTILENO. LA REACCION TIENE LUGAR EN PRESENCIA DED UN CATALIZADOR ALCALINO (HIDROXIDO, AMINA O TRIFLUORURO DE BORO), A TEMPERATURAS DE HASTA 150JC Y PRESIONES DE HASTA 7 KG/CM. SE EMPLEAN COMO AGENTES ESPUMANTES EN LA FLOTACION DE CARBONES O MENAS SULFURADAS U OXIDADAS.
