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(qiáng)的極性,可以與大部分有機(jī)溶劑互溶。而二甲苯是一種無色透明的有機(jī)溶劑,也可以與許多有機(jī)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(yīng)根據(jù)具體的實(shí)驗(yàn)條件進(jìn)行考慮。同時(shí),順酐和二甲苯都是有毒有害物質(zhì),使用時(shí)需要注意防護(hù)和操作規(guī)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?;渲?1 個(gè)乙烯基相連兩個(gè)羰基,所以化學(xué)性質(zhì)非常活潑,很容易通過光化反應(yīng)、加成反應(yīng)、酰胺化反應(yīng)、酯化反應(yīng)、磺化反應(yīng)、水合反應(yīng)、氧化反應(yīng)、還原反應(yīng)、加氫反應(yīng)等衍化產(chǎn)生眾多的下游產(chǎn)品,廣泛應(yīng)用于不飽和聚酯樹脂、涂料、油漆、油墨、工程塑料、醫(yī)藥、農(nóng)藥、食品、飼料、油品添加劑、造紙、紡織等行業(yè)。

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(xué)品如丁二酸酐、γ-丁內(nèi)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(chǎn)品的次級衍品如 PTMEG、PBT等,均屬于目前用途廣泛、國內(nèi)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.
