पहिलो, प् fhanhicl Sanhdridride ले लागूऔषधको निर्माणको क्षेत्रमा महत्त्वपूर्ण भूमिका खेल्छ। यो एन्टी-भग्नावशक्ति ड्रग्स, ग्यास्ट्रोनिटस्टिटर ड्रग्स, एन्टिबायोटिक, ईन्क्सिस ड्रग्स र अन्य लागूपदार्थको निर्माणको लागि एक प्रमुख कच्चा माल हो। In addition, phthalic anhydride is also a precursor for the preparation of various plant hormones such as growth hormone and auxin, which is of great significance for promoting plant growth and increasing crop yields.

दोस्रो, phhhhhahly Anhihddride पनि व्यापक रूप मा व्यापक रूपमा प्रयोग गरीन्छ। As an intermediate for dyes and spices, phthalic anhydride is used to make spices, pigments, synthetic fiber dyes, etc. Its unique chemical properties make it irreplaceable in these fields, adding rich colors and fragrances to people's lives.

थप रूपमा, प्र्थथेशलिक अन्हाइड्रिडले पनि प्लास्टिक र रबरको निर्माणमा महत्त्वपूर्ण भूमिका खेल्छ। It is an important raw material for the manufacture of polymer compounds such as polyphenylene ether, polyamide, and polyimide. These polymer compounds have excellent physical properties and chemical stability, and are widely used in automobiles, electronics, construction and other fields, providing strong support for the development of modern society.

जैविक सिन्थेसिस को क्षेत्रमा, phthakic Anhhddride सँग एक विस्तृत श्रृंखला छ। It can be used for carbonylation, propylene oxidation, preparation of activated carbon esters, dry hydrogenation, aldehyde and ketone esterification, nitric acid and alkaline oxidation. In inorganic synthesis, phthalic anhydride can be used to synthesize ammonium salts, and can also be used as the main polymerization agent for the synthesis of copper zinc sulfide. These synthetic reactions provide a rich material basis for the development of the chemical industry.

थप रूपमा, प्फेशलिक अन्च्छरले पनि राम्रो रसायनहरूको क्षेत्रमा महत्त्वपूर्ण अनुप्रयोगहरू राख्छ। It can be used for a variety of separation crystallization and catalytic reactions, and can also be used for the preparation and dispersion technology of various inorganic calcium sulfur polymers. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. In addition, phthalic anhydride can also be used as a raw material for insecticides and pesticides, playing an important role in ensuring the growth of crops and increasing yields.

औद्योगिक उत्पादनमा, प्र्थथिक enhihdride मुख्यतया विलायक र विचलित रूपमा प्रयोग गरिन्छ। Due to its low boiling point and high solubility, phthalic anhydride is widely used in petroleum refining and petrochemical industries as a cracking raw material. At the same time, it can also be used as a chromatographic analysis reagent and an extractant for spices, etc., providing an effective means for chemical analysis and spice extraction.
