March 17 (Reuters) - The mainstream quotation range for xylene in the South China market is 7,650-7,700 yuan/ton, unchanged from the previous trading day. Sinopec South China Company's listed price for xylene remains stable at 7,700 yuan/ton. In the previous trading day, the domestic toluene and xylene markets showed a strong and volatile trend, with rising crude oil prices and tight supply supporting market sentiment. However, downstream demand remains weak, leading to a pullback in intraday prices after an initial surge. The market is expected to maintain a volatile trend in the short term, with continued focus on international developments.
