Abstract

La presente se refiere a aminas de formulas I y II, y sus derivados, donde en la formula I: A y E se eligen independientemente de -CH2CH2- o -CH2CH2CH2-, n es un entero positivo, R1 y R2 se eligen independientemente de -H o -CS2 y en la formula II: A y E se eligen independientemente de -CH2CH2- o -CH2CH2CH2-, n es un entero positivo, R1 se elige independientemente de -H o -CS2 y R2 es un alquilo saturado, insaturado, lineal o ramificado, ciclico o aciclico de 1 a 22 carbonos o 1 a 22 carbonos de amida. Dichas aminas y derivados mejoran el intervalo de amortiguacion, y/o reducen la quelacion y otras interacciones negativas del amortiguador y el sistema a amortiguar. La reaccion de las aminas o poliaminas con varias moleculas forman poliaminas con diferentes pKa que extenderan el intervalo de amortiguacion; los derivados que dan como resultado poliaminas que tienen la misma pKa producen una mayor capacidad de amortiguacion. Los derivados que dan como resultados amortiguadores zwitterionicos mejoran el rendimiento al permitir un mayor intervalo de estabilidad.
