PURPOSE:To detect easily the concn. of an ion dissociative compd. to be added in a process for producing polyester in a soln. with high accuracy by measuring the electric conductivity of the soln. contg. said compd. or the quantity of electricity associated therewith. CONSTITUTION:The detection of an ion dissociative compd. to be added in a process for producing polyester in a concn. is detected by measuring the electric conductivity of the soln. contd. said compd. or the quantity of electricity associated therewith by noticing that the greater part of the compd. causes ion dissociation in a soln. The concn. is thus obtd. immediately with good accuracy without repeating laborious analyzing operations. |
