Application:

First, phthalic anhydride plays an important role in the field of drug manufacturing. It is a key raw material for the manufacture of anti-inflammatory drugs, gastrointestinal drugs, antibiotics, anticancer drugs and other drugs. Praeterea, phthaalum Anhydride est etiam praecursor pro praeparatio variis herba hormones ut incrementum hormone et Auxin, quod est magni momento pro promovendi herba incrementum et augendae seges cedit.

Secondly, phthalic anhydride is also widely used in the dye and fragrance industry. Sicut medium per aromatibus et aromatibus, phthaalio anhydride adhibetur ad aromata, pigmenta, synthetica fibra dyes, etc. eius unique eget proprietatibus facere irrepatibus in his agros, addendo dives colores et in his agris, addendo dives colores et in his agros, addendo dives colores et in his agris, addendo dives colores et in his agris, addendo dives colores et in his agris, addendo dives colores et in his agris, addendo dives colores et ad populum scriptor vitas.

In addition, phthalic anhydride also plays an important role in the manufacture of plastics and rubber. It is an important raw material for the manufacture of polymer compounds such as polyphenylene ether, polyamide, and polyimide. Haec polymer componit habere optimum corporalis proprietatibus et eget stabilitatem, et late in automobiles, electronics, constructione et aliis agri, providing fortis firmamentum pro progressionem modern societatis.

In the field of organic synthesis, phthalic anhydride has a wide range of applications. Potest adhiberi ad carbonylation, propylene oxidatio, praeparatio activated ipsum esters, sicco hydrogenation, aldehyde et ketone estterificatio, nitric acidum et alkaline oxidatio. In inorganicis synthesis, phthaalio anhydride potest esse ad summum salita, et potest etiam esse sicut principalis polymerization agente ad synthesis aeris Zinc sulfide. These synthetic reactions provide a rich material basis for the development of the chemical industry.

In addition, phthalic anhydride also has important applications in the field of fine chemicals. Potest adhiberi variis separationis crystallization et catalytic profectae, et potest etiam adhiberi ad praeparationem et dispersionem technology de variis inorganicis calcium sulphuris polymers. In mining processing, phthalic anhydride can be used for mineral processing of ore deposits to improve the mining efficiency and quality of ore. Praeterea, phthaalio anhydride potest etiam esse sicut rudis materiam ad insecticides et pesticides, ludens an maximus munus in ensuring incrementum segetes et augendae cedit.

In industrial production, phthalic anhydride is mainly used as a solvent and extractant. Ob suam humilis ferveret punctum et altum solubility, phthaalum anhydride est late in PETROLEUM conflans et Petrochemical Industria ut elit rudis materia. Simul, potest etiam esse in chromatographic analysis Reagent et extrahendum ad aromata, etc., providing efficax est pro eget analysis et spice extraction.

Insuper, phthaalio anhydride potest etiam esse solebat parare vanillin, determinare urina saccharo, parare varietate synergists et antifreeze, etc. est etiam unus ex rudis materiae pro Polyvyl CHLORIGHTESCERS et bonum choice pro Metal STabilizers et A bonum et CHLOR. In Flexilis et plastic vestibulum, phthaalio anhydride potest esse ut a rubber additive et plastic additive ut amplio uber perficientur et qualitas.
