Claim 1
Independent Claim
126 words
THE METHOD OF DETECTING A POTENTIALLY DANGEROUS BUILD-UP OF A HYDROPEROXIDE IN THE CLEAVAGE ZONE IN A PROCESS FOR CLEAVING HYDROPEROXIDE INTO OTHER PRODUCTS INCLUDING PHENOL COMPRISING PASSING A BLEED STREAM OF CLEAVAGE ZONE MIXTURE FROM SAID CLEAVAGE ZONE INTO CONTACT WITH ACID TO CLEAVE RESIDUAL HYDROPEROXIDE IN SAID STREAM, MAINTAINING THE TEMPERATURE OF SAID MIXTURE WHERE IT CONTACTS SAID ACID SUFFICIENTLY BELOW THE NORMAL BOILING POINT OF SAID MIXTURE SO THAT THE TEMPERATURE OF THE RESULTING MIXTURE OF SAID STREAM AND ACID WILL BE BELOW THE BOILING POINT OF SAID RESULTING MIXTURE, AND MEASURING THE TEMPERATURE RISE OF SAID RESULTING MIXTURE CAUSED BY THE HYDROPEROXIDE HEAT OF DECOMPOSITION AND THE ACID HEAT OF SOLUTION AS A MEASURE OF THE HYDROPEROXIDE CONCENTRATION IN SAID BLEED STREAM.
