Anhydride phtalic, lest għall-ġarr ~

Applikazzjoni:

L-ewwel, l-anhydride ftaliku għandu rwol importanti fil-qasam tal-manifattura tad-droga. Hija materja prima ewlenija għall-manifattura ta 'mediċini anti-infjammatorji, mediċini gastro-intestinali, antibijotiċi, mediċini kontra l-kanċer u mediċini oħra. 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.

It-tieni, l-anhydride ftaliku jintuża wkoll ħafna fl-industrija taż-żebgħa u tal-fwieħa. 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.

Barra minn hekk, l-anhydride ftaliku għandu wkoll rwol importanti fil-manifattura tal-plastik u l-gomma. Huwa materja prima importanti għall-manifattura ta 'komposti tal-polimeri bħal polifenilene ether, poliamide, u 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.

Fil-qasam tas-sinteżi organika, l-anhydride ftaliku għandu firxa wiesgħa ta 'applikazzjonijiet. 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. Dawn ir-reazzjonijiet sintetiċi jipprovdu bażi materjali rikka għall-iżvilupp tal-industrija kimika.

Barra minn hekk, l-anhydride ftaliku għandu wkoll applikazzjonijiet importanti fil-qasam tal-kimiċi fini. 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. Fl-ipproċessar tal-minjieri, l-anhydride ftaliku jista 'jintuża għall-ipproċessar minerali ta' depożiti ta 'minerali biex itejjeb l-effiċjenza tal-minjieri u l-kwalità tal-minerali. 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.

Fil-produzzjoni industrijali, l-anhydride ftaliku jintuża prinċipalment bħala solvent u estrattant. 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.
