Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
112 words
IN QUANTITATIVE ANALYSIS BY TIRATION INVOLVING THE QUANTITATIVE REACTION IN AN ELECTROLYTE OF A TIRATING AGENT WITH UNSATURATED HYDROCARBONS TO BE ANALYZED, THE IMPROVEMENT WHICH COMPRISES REGULATING THE AMOUNT OF TITRATING AGENT PRESENT IN THE ELECTROLYTE BY ELECTROLYTICALLY GENERATING BROMINE IN SITU, ESTABLISHING A REFERENCE POINT OF OROMINE CONTENTRATION IN SAID ELECTROYLTE, INTRODUCING THE UNSATURATED HYDROCARBONS TO BE ANALYZED, CONTROLLING THE CURRENT EMPLOYED IN THE ELECTROLYSIS SO AS TO EFECT THE GENERATION OF THE BORMINE AT A CONSTANT RATE, AMPEROMETRICALLY SENSING THE PRESENCE OF SAID REFERENCE POINT OF BROMINE CONCENTRATION AS AN INDICATION OF THE COMPLETION OF THE TIRATION OF SAID UNSATURATED HYDROCARBONS, AND DETERMINING THE TIME NECESSARY TO COMPLETE SUCH TIRATION.
