Process and apparatus for the analysis of mixtures of liquids

Claim 1

PROCESS FOR THE QUANTITATIVE DETERMINATION OF THE LOWEST BOILING COMPONENT OF A MIXTURE OF LIQUIDS, BY MEASURING THE DIFFERENCE BETWEEN THE BOILING TEMPERATURES OF SAID MIXTURE OF LIQUIDS AND A LIQUID USED FOR COMPRISIING CONTINOUSLY SUPPLYIING A FIRST SAMPLE OF SAIID MIXTURE OF LIQUIDS TO CONSTANT BOILING AND REFLUXING ALL VAPORS FORMED TO SAID FIRST SAMPLE; SIMULTANEOUSLY HEATING A SECOND SAMPLE OF SAID MIXTURE OF LIQUIDS TO CONSTANT BOILINGUNDER EQUAL PRESSURE AND DISTIILLING OFF FROM SAID SECOND SAMPLE SAID LOWEST BOILING COMPONENT BY FRACTIONATION AND REFLUXING ALL REMAINING VAPORS FORMED DURING SAID CONSTANT BOILING TO THE DISTILLATION RESIDUE THUS FORMED OF SAID SECOND SAMPLE SO THAT SAID SECOND SAMPLE WILL THEN CONSIST OF THE ORIGINAL MIXTURE OF LIQUIDS MINUS SAID LOWEST BOILING COMPONENT, AND MEASURING THE DIFFERENCE BETWEEN THE BOILING TEMPERATURES OF SAID DISTILLATION RESIDUE OF THE SECOND SAMPLE AND OF SAID UNCHANGED MIXTURE OF LIQUIDS OF THE FIRST SAMPLE.
