Automated process for the hydrolysis of titanium sulfate solutions
Abstract
Abstract THE HYDROLYSIS OF TITANIUM SULFATE SOLUTIONS IS PERFORMED AND CONTROLLED BY HEATING A SEEDED TITANIUM SULFATE SOLUTION WITH AGITATION WHILE SIMULTANEOUSLY MEASURING THE REFLECTANCE OF THE RESULTING SUSPENSION, UNTIL A CRITICAL POINT IS ATTAINED AS INDICATED BY A SUBSTANTIAL CHANGE IN THE RATE OF REFLECTANCE PER UNIT OF HYDROLYSIS TIME, ALLOWING THE SOLUTION TO REMIAN QUIESCENT FOR FROM 5 TO 60 MINUTES, THEN RESUMING THE HEATING OF THE SOLUTION UNTIL THE HYDROLYSIS PRODUCES THE DESIRED YIELD OF TITANIUM HYDRATE. THE MEASUREMENT OF REFLECTANCE MAY BE MADE BY PHOTOELECTRIC MEANS, AND THE POINT OF INFLECTION OF THE REFLECTANCE CURVE OR ITS FIRST OR SECOND DERIVATIVE WITH RESPECT TO TIME MAY BE USED TO CONTROL THE HYDROLYSIS PROCESS.
