| titleOfInvention | Production of precursor pitch for general purpose carbon fiber |
| abstract | PURPOSE: To efficiently obtain the subject pitch having excellent spinnability and capability of becoming infusible and 100% optical isotropy at a low cost by quenching a high-temperature treated pitch in directly heat exchanging with a precursor pitch of low-temperature. n CONSTITUTION: A tar pitch is purified and heat-treated at high-temperature, then quenched by pouring into a quenching tank previously containing a low- temperature precursor pitch in a range of 250-330°C in stirring state to be directly subjected to heat-exchange with said low-temperature pitch to afford the subject pitch made from suppressed polycondensation and aromatizing reaction. Besides, 350-420°C temperature and ≤50mmHg pressure are generally preferable as the high-temperature treatment condition. n COPYRIGHT: (C)1991,JPO&Japio |
