Abstract
UNA MEJORA EN EL PROCEDIMIENTO DE PREPARACION DE UN ALQUILPOLIGLUCOSIDO QUE CONTIENE UN GRUPO ALQUILO DE CADENA LARGA DE 10 ATOMOS DE CARBONO O MAS MEDIANTE LA REACCION DE UN SACARIDO Y UN ALCOHOL DE CADENA LARGA EN PRESENCIA DE UN CATALIZADOR ACIDO, EN PARTICULAR UNA MEJORA EN EL PROCEDIMIENTO PARA INHIBIR O MINIMIZAR EL ENSUCIAMIENTO DEL CONDENSADOR DURANTE EL TRATAMIENTO BIEN DURANTE LA RETIRADA DE AGUA DEL REACTOR PARA FOMENTAR EL FIN DE LA REACCION O BIEN DURANTE UN TRATAMIENTO SUBSIGUIENTE DEL CHORRO DEL PRODUCTO DE REACCION EN DONDE EL CHORRO SE CALIENTA A TEMPERATURAS ELEVADAS BAJO VACIO PARA RETIRAR EL EXCESO DE ALCOHOL Y AGUA RESIDUAL, O SE INTRODUCE AGUA EN EL CHORRO DE TRATAMIENTO MEDIANTE UNOS EYECTORES DE VAPOR EN UN EVAPORADOR, TRAS ABANDONAR EL REACTOR. LA MEJORA CONSISTE EN AÑADIR UN ALCOHOL QUE TENGA UNA CADENA DE CARBONO CON UN NUMERO INFERIOR A LA CADENA DE CARBONO DEL GRUPO ALQUILO DEL PRODUCTO DE ALQUILPOLIGLUCOSIDO JUNTO CON EL ALCOHOL REACCIONANTE PARA OBTENER EL POLIGLUCOSIDO, O EN EL CHORRO DEL PRODUCTO DURANTE LA EVAPORACION DEL EXCESO DE ALCOHOL Y DE AGUA RESIDUAL.
