顺酐，又称顺丁烯二酸酐，马来酸酐，2,5-呋喃二酮等。斜方晶系无色针状或片状晶体。有强烈刺激气味，溶于乙醇、乙醚和丙酮，难溶于石油醚和四氯化碳。与热水作用而成马来酸。

Maleic anhydride, also known as Maleic anhydride, maleic anhydride, 2,5-furandione, etc. The rhombic crystal system is a colorless needle shaped or sheet shaped crystal. It has a strong pungent smell and is soluble in ethanol, ether and acetone, but insoluble in Petroleum ether and carbon tetrachloride. It reacts with hot water to form Maleic acid.

主要用于不饱和聚酯树脂、醇酸树脂、农药马拉硫磷、低毒农药4049、长效碘胺的原料。也是涂料、马来松香、聚马来酐、顺酐-苯乙烯共聚物的共聚单体，也是油墨助剂、造纸助剂、增塑剂、酒石酸、富马酸、四氢呋喃等的有机化工原料。

It is mainly used as raw material for producing unsaturated polyester resin, alkyd resin, pesticide Malathion, efficient and low toxic pesticide 4049, and long-acting iodamine. It is also a comonomer of coatings, maleic rosin, polymaleic anhydride, maleic anhydride styrene copolymer, and an organic chemical raw material for the production of ink additives, papermaking additives, plasticizers, Tartaric acid, fumaric acid, tetrahydrofuran, etc.

供应成本方面

In terms of supply costs

顺酐厂家发现近两年以来，顺酐市场产能增速较快，一体化拟在建项目众多，主要是正丁烷法，苯氧化法顺酐装置成本较高，原料纯苯供应量减少且长期处于高位，同时面临压力问题，苯法顺酐工厂多数停产。

Maleic anhydride manufacturers have found that in the past two years, the production capacity of the maleic anhydride market has grown rapidly, and there are many integrated projects under construction, mainly the n-butane method. The cost of the benzene oxidation method maleic anhydride device is relatively high, the supply of raw material pure benzene has decreased, and the price has been at a high level for a long time. At the same time, facing environmental pressure, most of the benzene method maleic anhydride factories have ceased production.

出口领域

Export sector

2021-2022年顺酐出口市场迎来爆发式增长期，2021年出口量同比增长120.9%，顺酐出口量占其年产量比例可达15%，出口量的增长，对其产品形成重要支撑。

The export market of maleic anhydride experienced an explosive growth period from 2021 to 2022, with a year-on-year increase of 120.9% in export volume. The proportion of maleic anhydride exports to its annual production can reach 15%, and the growth of export volume provides important support for its product prices.

政策扶持

National policy support

精细化工行业的发展需要基础化工行业的支持，我国已建立起较为完整的石化工业体系，一些重要化工原料具备较大的能力和产量基数，我国精细化工企业在竞争中具备一定的比较优势。

The development of the fine chemical industry requires the support of the basic chemical industry. China has established a relatively complete petrochemical industry system, and some important chemical raw materials have a large production capacity and output base. China's fine chemical production enterprises have a certain comparative advantage in international competition.

下游需求

Downstream demand

顺酐主要消费领域为不饱和聚酯树脂，近年产能增速稳定，但受疫情及经济因素影响，2022年对顺酐的支撑作用减弱。

The main consumer area of maleic anhydride is unsaturated polyester resin. In recent years, the production capacity growth rate has been stable, but due to the impact of the epidemic and economic factors, the support for maleic anhydride will weaken in 2022.

但顺酐也有一些新兴的应用领域，例如BDO、丁二酸及顺酐酸酐生物。顺酐及酸酐衍生物行业符合我国的产业政策，产品下游应用行业多属于鼓励发展行业，产品和使用过程中对环境影响较小，绿色的产品特征使其拥有广阔的发展前景，获得了相关行业政策的支持。

But there are also some emerging applications for maleic anhydride, such as BDO, succinic acid, and maleic anhydride biology. The maleic anhydride and anhydride derivative industries comply with China's industrial policies, and the downstream application industries of products are mostly encouraged by the state for development. The production and use of products have little impact on the environment, and the green and environmentally friendly product characteristics make them have broad development prospects, which have been supported by relevant industrial policies.

全球对的关注度亦持续提升，限塑令出台，可降解塑料规模扩大显著，带动原料丁二酸及其原料顺酐的需求持续提升，导致顺酐曾有过高位情况出现。

The global attention to environmental protection has also continued to increase, with the introduction of plastic restriction orders and a significant expansion of the scale of degradable plastics, driving the continuous increase in demand for raw materials such as succinic acid and maleic anhydride, which has led to high prices for maleic anhydride.

在禁塑令的推动下，可降解塑料在未来将会逐步替代传 统塑料，PLA/PBAT/PBS 都是可降解塑料材料，其中 PBS 所需要原料 BDO 和丁二酸 都可以通过顺酐，同时 BDO 也是 PBAT 的重要原料之一，顺酐法工艺也更为，由此顺酐存在一定潜在需求。更多相关内容就来我们网站http://www.jnjhhg.cn咨询吧！

Under the promotion of the ban on plastic production, degradable plastics will gradually replace traditional plastics in the future. PLA/PBAT/PBS are all degradable plastic materials, and the raw materials required for PBS, BDO and succinic acid, can be produced through maleic anhydride. BDO is also an important raw material for PBAT, and the maleic anhydride process is also more environmentally friendly. Therefore, there is a certain potential demand for maleic anhydride.
