順酐和二甲苯互溶，在一定條件下可以形成溶液。順酐在室溫下為無色透明液體，具有較強的極性，可以與大部分有機溶劑互溶。而二甲苯是一種無色透明的有機溶劑，也可以與許多有機物互溶，包括順酐。需要注意的是，順酐與二甲苯的溶解度受到溫度、濃度、壓力等條件的影響，應根據具體的實驗條件進行考慮。同時，順酐和二甲苯都是有毒有害物質，使用時需要注意防護和操作規范。

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.

酐由于含有共軛順酰基，其中 1 個乙烯基相連兩個羰基，所以化學性質非常活潑，很容易通過光化反應、加成反應、酰胺化反應、酯化反應、磺化反應、水合反應、氧化反應、還原反應、加氫反應等衍化產生眾多的下游產品，廣泛應用于不飽和聚酯樹脂、涂料、油漆、油墨、工程塑料、醫藥、農藥、食品、飼料、油品添加劑、造紙、紡織等行業。

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.

以順酐為原料的化學品如丁二酸酐、γ-丁內酯、1,4-丁二醇、四氫呋喃、四氫苯酐、六氫苯酐、L-天門冬氨酸、丙氨酸以及這些產品的次級衍品如 PTMEG、PBT等，均屬于目前用途廣泛、國內市場暢銷的化工原料。

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.
