Abstract

ZWITERÍONS DERIVADOS DE DISSULFETO DE CARBONO. Trata-se de aminas e derivados de amina que melhoram a faixa de tamponagem e/ou reduzem a quelação e outras interações negativas do tampão e do sistema a ser tamponado. A reação de aminas ou poliaminas com várias moléculas para formar poliaminas com diferentes pKas estenderá a faixa de tamponagem, derivados que resultam em poliaminas que têm o mesmo pKa produzem uma capacidade de tamponagem maior. Derivados que resultam em tampões zwiteriônicos melhoram o rendimento permitindo uma faixa maior de estabilidade.CARBON DISULFIDE DERIVATIVE ZWITERIONS. These are amines and amine derivatives that improve the buffering range and/or reduce chelation and other negative interactions of the buffer and the system to be buffered. Reacting amines or polyamines with various molecules to form polyamines with different pKas will extend the buffering range, derivatives that result in polyamines having the same pKa produce a higher buffering capacity. Derivatives that result in zwitterionic plugs improve yield by allowing a wider range of stability.
