Abstract:
Alkylation-acid end point detector for measuring the titratable acidity of the acid. It employs an electrical titration cell to generate a potential that is related to the acidity pH of the acid. It amplifies and differentiates the potential followed by amplifying the first derivative signal to produce a sharp acid end point signal without using a second derivative.
