March 11 (Reuters) - The mainstream spot quotation range for toluene in East China is between 7,150 and 7,180 yuan per ton, down 20 yuan per ton from the previous trading day. Overnight, crude oil and aromatics futures both experienced significant declines, creating a dual negative impact from both cost and futures market pressures. As a result, toluene and xylene prices have notably retreated, erasing previous gains. Market sentiment remains generally weak throughout the day, and it is expected that toluene and xylene markets will continue to experience a volatile decline.
