Core Insights - The domestic phenol industry is expected to recover as overseas production capacity is being shut down, particularly in Europe, due to high energy costs and carbon tax policies [2][3]. - Domestic phenol prices are currently at their lowest since June 2023, with an average price of 6,562 RMB/ton in July 2025, compared to historical averages of 8,859 RMB/ton in 2021 and 10,023 RMB/ton in 2022 [1][2]. - The effective production capacity of domestic phenol has increased significantly from 3.33 million tons/year in 2021 to 6.57 million tons/year in 2024, with a compound annual growth rate (CAGR) of 25.43% [2]. Summary by Sections Price Trends - The average price of domestic phenol in the first half of 2025 is projected to be 7,026 RMB/ton, indicating a downward trend from previous years [1]. - Historical price data shows a significant decline from 10,023 RMB/ton in 2022 to 7,914 RMB/ton in 2024 [1]. Production Capacity and Consumption - Domestic phenol production capacity growth has slowed, with a CAGR of 3.57% expected in 2024, down from 37.99% between 2021 and 2023 [2]. - Apparent consumption of domestic phenol has increased from 3.08 million tons in 2021 to 5.24 million tons in 2024, with a CAGR of 19.37% [2]. Import and Export Dynamics - Domestic phenol imports have decreased significantly from 522,300 tons in 2021 to 249,600 tons in 2024, reflecting a CAGR of -21.82% [2]. - Exports have also declined from 135,100 tons in 2021 to 79,100 tons in 2024, although a notable increase of 184.81% is expected in 2024 [2]. Investment Recommendations - The report suggests that the exit of overseas phenol production capacity will likely boost domestic production and sales, benefiting companies in the sector [3]. - Key companies to watch include Weiyuan Co.

• 2025年纯苯供应端压力持续高企。国内方面,下半年裂解装置投产高峰及炼厂开工恢复将推动产量显著增加,全年 表观需求预计增长8.9%,增速较前两年明显回落但仍处高位。1-5月纯苯进口同比+64%,增量主要来自韩国。预计 下半年月均进口量将稳定在45万吨左右高位,全年进口预期上调至555万吨,同比+28.7%。加氢苯产量预计全年持 平,下半年其市场地位或因期货上市交割规则而有所提升。下游需求结构变化显著,苯乙烯成为核心支撑,而其他 四小下游整体增速放缓且表现分化:己内酰胺和苯胺由去年的强势转为明显弱势,全年表需增速预计分别仅为+7% 和-8%;己二酸维持弱势,全年表需预计下滑7%;相对亮眼的是苯酚,受益于新产能推迟、老装置退出及下游PC高 产,利润修复明显,全年表需预计增长+7%。供增需减格局之下,纯苯库存仍然维持高位为主。 • 苯乙烯上半年得益于上半年海外供应收缩及下游产量偏高,维持了高利润、高开工、低库存的格局,并承接了纯 苯环节的让利。然而,下半年格局面临逆转:供应端,随着国内外装置大规模重启及潜在新产能投放,叠加海外 供应恢复,苯乙烯供应将显著修复。需求端,主要下游家电排产增速乏力,内需疲软叠加出口受 ...

Core Viewpoint - The article provides a comprehensive analysis of the pure benzene industry, highlighting its production processes, supply chain dynamics, and market trends, particularly focusing on the impact of downstream demand and global trade flows [3][5][17]. Summary by Sections Pure Benzene Overview - Benzene (C6H6) is a colorless, flammable liquid that serves as a fundamental petrochemical raw material, indicating the development level of a country's petrochemical industry [3][12]. Pure Benzene Industry Chain - The main downstream products of pure benzene include styrene, caprolactam, phenol, aniline, and adipic acid, with styrene consumption being the largest but declining in recent years due to real estate market influences [12][16]. Production Process - Pure benzene is produced as a byproduct in various chemical processes, with its output influenced by the profitability of producing other chemicals like PX and the demand for blending oil [16]. Global Capacity and Distribution - Global pure benzene capacity has accelerated, primarily driven by China, with Northeast Asia accounting for nearly half of the total capacity [17][24]. Trade Flows - The global trade flow of pure benzene moves from major production areas to consumption regions, with China, the US, and Europe being the primary consumers [20][41]. Domestic Capacity and Production - By the end of 2024, China's pure benzene capacity is projected to reach 25.73 million tons, with significant capacity additions in 2022 and 2023, although growth is expected to slow in 2024 [24]. Seasonal Operation Rates - The operational rates of domestic pure benzene facilities exhibit seasonality, aligning with refinery maintenance schedules, particularly in spring and autumn [33]. Downstream Demand - Downstream demand for pure benzene has been increasing, especially since 2021, driven by the commissioning of styrene and other downstream facilities, although the share of styrene has been declining [35]. Import and Export Dynamics - Domestic pure benzene is primarily imported, with significant imports from South Korea and Southeast Asia, while exports remain minimal [41]. Profitability - The profitability of pure benzene production is typically assessed through the price spread between pure benzene and naphtha, with variations depending on market conditions [46]. Supply and Demand Balance - The supply-demand balance for pure benzene is influenced by various factors, including production costs and downstream demand fluctuations [50]. Futures Contracts - Futures contracts for pure benzene are traded on the Dalian Commodity Exchange, with specific trading units and delivery standards outlined [53][54]. Delivery Standards - The delivery standards for pure benzene include specifications for appearance, purity, and various chemical content limits, ensuring quality control in trading [54][55]. Delivery Areas and Pricing - Delivery areas for pure benzene are strategically chosen to facilitate trade, with pricing adjustments based on regional supply and demand dynamics [56].
科学家解码蝗虫群聚信息素的生物合成途径与行为操控
Jing Ji Guan Cha Wang· 2025-06-30 09:27
经济观察网讯 据动物研究所消息,昆虫信息素作为昆虫体内各种腺体或细胞产生并分泌到体外的微量 化学物质,是昆虫种内和种间通讯的化学媒介,在昆虫的求偶、交配、觅食、聚集、产卵、导航定向、 防御报警和种间识别等行为中发挥重要作用。因此,开发与利用昆虫信息素是实现精准调控害虫行为、 推动害虫绿色可持续防控发展的突破方向。而揭示昆虫信息素的合成途径是实现这种绿色防控策略的必 要环节。尽管已有超过3000种昆虫的信息素被发现和鉴定,但全面揭示一个特定的信息素在昆虫体内的 生物合成途径鲜有报道。 4VPMTs是4VA生物合成的关键酶,也是抑制蝗虫聚集的重要靶点。4-硝基苯酚(4NP)通过竞争性结 合4VPMTs来抑制4VA生物合成。作为底物类似物,4NP酚羟基的亲核性因吸电子硝基而下降,使其成 为反应活性较弱的底物。4NP与4VPMTs的结合亲和力高于4VP,进而可以竞争性占据酶活性位点。从 蛋白结构特征来看,4NP与4VPMTs的特异性相互作用既保证了抑制剂的选择性,又能最大限度避免干 扰其他代谢通路时产生的脱靶效应。 该研究通过解析蝗虫群聚信息素4VA的生物合成路径,精准鉴定关键合成酶,并以此为靶点设计出高效 特异的小 ...
