Abstract

La presente invencion se refiere a una clase de zwitterion amino especificamente se refiere a un colector de mineria y su amina, y sales relevantes, donde: R y R´ se seleccionan independientemente de -H o -CS2H, n es entero no negativo. Una amina y derivados de amina mejoran el intervalo de amortiguacion y/o reducen la quelacion y otras interacciones negativas del amortiguador y el sistema que se amortiguara, los derivados que dan como resultados amortiguadores zwitterionicos, mejoran el rendimiento ya que permiten un mayor intervalo de estabilidad, siendo util como dispersante, quelante, reticulante, antimicrobiano, conservante de sistemas organicos y amortiguadores de pH en sistemas de perforacion de yacimientos petroliferos, especificamente el zwitterion de la invencion es util como colector en la mineria.The present invention refers to a class of amino zwitterion specifically refers to a mining collector and its amine, and relevant salts, where: R and R 'are independently selected from -H or -CS2H, n is a non-negative integer. An amine and amine derivatives improve the buffer range and / or reduce chelation and other negative interactions of the buffer and the system to be buffer, derivatives that result in zwitterionic buffers, improve performance by allowing a greater range of stability. Being useful as a dispersant, chelator, crosslinking agent, antimicrobial, preservative of organic systems and pH buffers in oil field drilling systems, specifically the zwitterion of the invention is useful as a collector in mining.
