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.This refers to amines of formulas I and II, and their derivatives, where in formula I: A and E are chosen independently of -CH2CH2- or -CH2CH2CH2-, n is a positive integer, R1 and R2 are chosen independently of -H or -CS2 and in formula II: A and E are independently chosen from -CH2CH2- or -CH2CH2CH2-, n is a positive integer, R1 is independently chosen from -H or -CS2 and R2 is a saturated, unsaturated alkyl , linear or branched, cyclic or acyclic with 1 to 22 carbons or 1 to 22 amide carbons. Said amines and derivatives improve the buffer range, and/or reduce chelation and other negative interactions of the buffer and the system to be buffered. The reaction of amines or polyamines with various molecules forms polyamines with different pKa that will extend the buffer range; Derivatives resulting in polyamines having the same pKa produce greater buffering capacity. Derivatives that result in zwitterionic dampers improve performance by allowing a greater range of stability.
