Calorimetric analysis for control of catalytic polymerization reactions

Claim 1

A METHOD FOR THE INTRODUCTION INTO A CATALYTIC REACTION ZONE OF THE AMOUNT OF CATALYST NECESSARY TO OBTAIN DESIRED PROPERTIES OF A PRODUCT OF THE REACTION COMPRISING PASSING A FEED STREAM INTO SAID REACTION ZONE, WITHDRAWING A SAMPLE FROM SAID FEED STREAM, PASSING THE THUS WITHDRAWN SAMPLE INTO AN ANALYZING ZONE, INTRODUCING INTO SAID SAMPLE IN SAID ANALYZING ZONE IN THE PRESENCE OF AT LEAST ONE TERMINAL ACETYLENIC HYDROCARBON A MATERIAL WHICH REACTS WITH CATALYST POISONS CONTAINED IN SAID SAMPLE, SAD MATERIAL CONSISTING ESSENTIALLY OF AN ORGANOLITHIUM COMPOUND OF THE FORMULA R(LI)X, WHERE R IS A HYDROCARBON RADICAL SELECTED FROM THE GROUP CONSISTING OG ALIPHATIC, CYCLOALIPHATIC, AND AROMATIC RADICALS AND CONTAINS FROM 1 TO 20, INCLUSIVE, CARBON ATOMS, AND X IS AN INTEGER FROM 1 TO 4, INCLUSIVE, DETECTING A CHANGE IN COLOR OF THE SAMPLE RESULTING FROM THE REACTION OF SAID MATERIAL WITH SAID TERMINAL ACETYLENIC HYDROCARBON, WHICH SIGNIFIES THE SUBSTANTIALLY COMPLETE REACTION OF THE CATALYST POISONS CONTAINED THEREIN, AND INTRODUCING CATAYLST INTO SAID REACTION ZONE AT A RATE RESPONSIVE TO THE AMOUNT OF SAID MATERIAL ADDED TO SAID SAMPLE PRIOR TO THE DETECTION OF SAID CHANGE IN COLOR.

Claim 2

A METHOD FOR THE INTRODUCTION INTO A CATALYTIC REACTION ZONE OF THE AMOUNT OF CATALYST NECESSARY TO OBTAIN DESIRED PROPERTIES OF A PRODUCT OF THE REACTION COMPRISING PASSING A FEED STREAM INTO SAID REACTION ZONE, WITHDRAWING A SAMPLE FROM SAID FEED STREAM, PASSING THE THUS WITHDRAWN SAMPLE INTO AN ANALYZING ZONE, INTRODUCING INTO SAID SAMPLE IN SAID ANALYZING ZONE IN THE PRESENCE OF AT LEAST ONE TERMINAL ACETYLENIC HYDROCARBON A MATERIAL WHICH REACTS WITH CATALYST POISONS CONTAINED IN SAID SAMPLE, SAD MATERIAL CONSISTING ESSENTIALLY OF AN ORGANOLITHIUM COMPOUND OF THE FORMULA R(LI)X, WHERE R IS A HYDROCARBON RADICAL SELECTED FROM THE GROUP CONSISTING OG ALIPHATIC, CYCLOALIPHATIC, AND AROMATIC RADICALS AND CONTAINS FROM 1 TO 20, INCLUSIVE, CARBON ATOMS, AND X IS AN INTEGER FROM 1 TO 4, INCLUSIVE, DETECTING A CHANGE IN COLOR OF THE SAMPLE RESULTING FROM THE REACTION OF SAID MATERIAL WITH SAID TERMINAL ACETYLENIC HYDROCARBON, WHICH SIGNIFIES THE SUBSTANTIALLY COMPLETE REACTION OF THE CATALYST POISONS CONTAINED THEREIN, AND INTRODUCING CATAYLST INTO SAID REACTION ZONE AT A RATE RESPONSIVE TO THE AMOUNT OF SAID MATERIAL ADDED TO SAID SAMPLE PRIOR TO THE DETECTION OF SAID CHANGE IN COLOR.
