METHOD FOR MEASURING THE CONTENT OF A COAL-TAR PITCH, CAPABLE OF QUANTITIVELY MEASURING THE CONTENT OF A COAL-TAR PITCH WITHIN A COAL-TAR

摘要

PURPOSE: A method for measuring the content of a coal-tar pitch is provided to accurately analyze the content of a coal-tar pitch before purification, thereby controlling a production amount by predicting a generation amount of the coal-tar pitch before the purification.;CONSTITUTION: A method for measuring the content of a coal-tar pitch is as follows. A coal-tar is heated after measuring the weight of the coal-tar(S110). The weight of a coal-tar pitch remained after volatilization so that whether constant weight is obtained or not is judged(S120). If the constant weight is obtained, the content of the coal-tar pitch is analyzed(S130).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) Finish; (S110) Heating step; (S120) Content determining step; (S130) Content analyzing step
