顺酐和二甲苯互溶，在一定条件下可以形成溶液。顺酐在室温下为无色透明液体，具有较强的极性，可以与大部分有机溶剂互溶。而二甲苯是一种无色透明的有机溶剂，也可以与许多有机物互溶，包括顺酐。需要注意的是，顺酐与二甲苯的溶解度受到温度、浓度、压力等条件的影响，应根据具体的实验条件进行考虑。同时，顺酐和二甲苯都是有毒有害物质，使用时需要注意防护和操作规范。

Maleic anhydride and xylene are miscible and can form a solution under certain conditions. Maleic anhydride is a colorless and transparent liquid at room temperature, with strong polarity, and can be miscible with most organic solvents. Xylene is a colorless and transparent organic solvent that can also be miscible with many organic compounds, including maleic anhydride. It should be noted that the solubility of maleic anhydride and xylene is influenced by conditions such as temperature, concentration, and pressure, and should be considered based on specific experimental conditions. Meanwhile, both maleic anhydride and xylene are toxic and harmful substances, and safety precautions and operating procedures should be taken when using them.

酐由于含有共轭顺酰基，其中 1 个乙烯基相连两个羰基，所以化学性质非常活泼，很容易通过光化反应、加成反应、酰胺化反应、酯化反应、磺化反应、水合反应、氧化反应、还原反应、加氢反应等衍化产生众多的下游产品，广泛应用于生产不饱和聚酯树脂、涂料、油漆、油墨、工程塑料、医药、农药、食品、饲料、油品添加剂、造纸、纺织等行业。

Anhydride, due to its conjugated cis acyl group, in which one vinyl group is connected to two carbonyl groups, has very active chemical properties and can easily generate numerous downstream products through photochemical reactions, addition reactions, amidation reactions, esterification reactions, sulfonation reactions, hydration reactions, oxidation reactions, reduction reactions, hydrogenation reactions, etc. It is widely used in the production of unsaturated polyester resins, coatings, paints, inks, engineering plastics, pharmaceuticals, pesticides, food, feed, oil additives, papermaking, textiles and other industries.

以顺酐为原料生产的化学品如丁二酸酐、γ-丁内酯、1,4-丁二醇、四氢呋喃、四氢苯酐、六氢苯酐、L-天门冬氨酸、丙氨酸以及这些产品的次级衍生产品如 PTMEG、PBT等，均属于目前用途广泛、国内市场畅销的化工原料。

Chemicals produced from maleic anhydride, such as succinic anhydride γ- Butanelactone, 1,4-butanediol, tetrahydrofuran, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, L-aspartic acid, alanine, and their secondary derivatives such as PTMEG and PBT are all widely used and best-selling chemical raw materials in the domestic market.
