Littalyske anhydride, ree foar ferstjoering ~

Oanfraach:

Earst spilet Litalyk anhydride in wichtige rol yn it fjild fan drugfabrikaasje. It is in wichtige grûnstof foar de fabrikaazje fan anty-inflammatoire drugs, gastrointestinale drugs, antibiotika, antybiotika, antybliotika, antikanker drugs en oare drugs. 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.

Twad, is Litalyske anhydride ek breed brûkt yn 'e kleurstof- en geur-yndustry. 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.

Derneist spilet Litalyk anhydride ek in wichtige rol yn 'e fabrikaazje fan plestik en rubber. It is in wichtich rau materiaal foar de fabrikaazje fan polypersjûtsingen lykas polyphenylene eter, polyamide, en 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.

Op it mêd fan organyske synthese hat phthalic anhydride in breed skala oan applikaasjes. 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. Dizze synthetyske reaksjes leverje in rike messenbasis foar de ûntwikkeling fan 'e gemyske yndustry.

Derneist hat Litalyk anhydride ek wichtige applikaasjes yn it fjild fan fyn gemikaliën. 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. By miningferwurking kin phthalic anhydride brûkt wurde foar mineraalferwurking fan ore ôfsettings om de mining effisjinsje en kwaliteit fan ore te ferbetterjen. 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.

Yn yndustriële produksje wurdt fytalykmasjine fral brûkt as solvent en ekstraktysk. 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.
