What are the manufacturing processes of homophthalic dianhydride?

What are the manufacturing processes of homophthalic dianhydride?

Homophthalic dianhydride is an important intermediate that is widely used in a number of applications, such as polyesters, resins, fibers, etc. As the demand for its application continues to increase, its production process is receiving more and more attention. In this paper, we will introduce several common production processes of homophthalic dianhydride. 1. 单相溶解 - 氧化法 该工艺是目前Z常用的生产工艺，其原理是将苯和四甲醚混合后，加入催化剂和氧气进行氧化反应。在反应的过程中，产生的气体会在溶液中产生气泡而不影响反应的进行。反应后，通过普鲁士蓝试剂判断反应是否达到预期效果。Z终得到均苯四甲酸二酐的产率约为85％。这个方法的优点在于操作简单易懂，容易进行批量生产，缺点是反应过程中存在有害气体排放。

What will be the market size of homophthalic dianhydride in the coming years?

What will be the market size of homophthalic dianhydride in the coming years?

Homophthalic tetracarboxylic dianhydride (PMDA) is an organic compound that is commonly used to make high-performance materials such as polyimide (PI) and polyetherimide (PEI). These materials have a wide range of applications in aerospace, automotive, electronics, medical, and energy fields, so the PMDA market size will continue to grow in the coming years. 根据市场研究公司的数据，2019年全球PMDA市场规模约为2.4亿美元，预计到2024年将达到3.2亿美元，年复合增长率约为5.5%。其中，亚太地区将成为Z大的市场，占据全球PMDA市场的40%以上。

How should I store and use homophthalic dianhyd

How should I store and use homophthalic dianhyd

Homophthalic dianhydride is an organic compound with the chemical name of 1,2,4,5-benzenetetracarboxylic dianhydride, abbreviated as PMDA, which is commonly used as a raw material for the manufacture of polymer materials and other chemical products. In storage and use, some important issues need to be noted. 首先，均苯四甲酸二酐的储存必须避免受潮。这种化合物会吸收空气中的水分，特别是在高湿度环境下，因此保管它应该在干燥的条件下。可以使用干燥剂或真空密封袋来保存，以减少潮湿对化合物的影响。此外，在储存时也不能与水或潮湿的前体物（如苯）混在一起。 其次，均苯四甲酸二酐的储存应该在避光的情况下进行。这种化合物不稳定于紫外线和日光下，因此必须保持在黑暗中。Z好选择不透明的容器将其储存。
