Phthalic Anhydride 99%, Shirye don jigilar kaya ~

Aikace-aikace:

Na farko, phthalic anhydride yana taka muhimmiyar rawa a fagen kera magunguna. Abu ne mai mahimmanci don kera magungunan hana kumburi, magungunan gastrointestinal, maganin rigakafi, magungunan ciwon daji da sauran magunguna. Bugu da kari, phthalic anhydride shi ma wani mafari ne na shirye-shiryen samar da kwayoyin halittar shuka iri-iri kamar su hormone girma da auxin, wanda ke da matukar muhimmanci wajen bunkasa ci gaban shuka da kara yawan amfanin gona.

Na biyu, phthalic anhydride shima ana amfani dashi sosai a masana'antar rini da kamshi. A matsayin tsaka-tsakin rini da kayan kamshi, ana amfani da phthalic anhydride don yin kayan kamshi, pigments, rini na fiber na roba, da dai sauransu. Abubuwan sinadarai na musamman sun sa ba za a iya maye gurbinsa ba a waɗannan fagage, yana ƙara launuka masu yawa da ƙamshi ga rayuwar mutane.

Bugu da kari, phthalic anhydride shima yana taka muhimmiyar rawa wajen kera robobi da roba. Yana da mahimmancin albarkatun ƙasa don kera mahaɗan polymer kamar polyphenylene ether, polyamide, da polyimide. Wadannan mahadi na polymer suna da kyawawan kaddarorin jiki da kwanciyar hankali na sinadarai, kuma ana amfani da su sosai a cikin motoci, kayan lantarki, gine-gine da sauran fannoni, suna ba da tallafi mai ƙarfi don ci gaban al'ummar zamani.

A cikin filin hada-hadar kwayoyin halitta, phthalic anhydride yana da aikace-aikace masu yawa. Ana iya amfani dashi don carbonylation, propylene oxidation, shirye-shirye na esters carbon da aka kunna, busassun hydrogenation, aldehyde da ketone esterification, nitric acid da alkaline oxidation. A cikin inorganic kira, phthalic anhydride za a iya amfani da su hada ammonium salts, kuma za a iya amfani da a matsayin babban polymerization wakili don kira na jan karfe zinc sulfide. Waɗannan halayen haɗin gwiwar suna ba da tushen wadataccen abu don haɓaka masana'antar sinadarai.

Bugu da ƙari, phthalic anhydride shima yana da mahimman aikace-aikace a fagen sinadarai masu kyau. Ana iya amfani da iri-iri na rabuwa crystallization da catalytic halayen, da kuma za a iya amfani da shiri da watsawa fasahar na daban-daban inorganic alli sulfur polymers. A cikin sarrafa ma'adinai, ana iya amfani da phthalic anhydride don sarrafa ma'adinai na ma'adinan tama don inganta haɓakar ma'adinai da ingancin tama. Bugu da ƙari, ana iya amfani da phthalic anhydride a matsayin ɗanyen kayan kashe kwari da magungunan kashe qwari, yana taka muhimmiyar rawa wajen tabbatar da ci gaban amfanin gona da haɓaka amfanin gona.

A cikin samar da masana'antu, phthalic anhydride an fi amfani dashi azaman ƙarfi da cirewa. Saboda ƙarancin tafasawarsa da babban solubility, phthalic anhydride ana amfani dashi sosai a cikin tace man fetur da masana'antar petrochemical a matsayin ɗanyen abu mai fashewa. A lokaci guda kuma, ana iya amfani da shi azaman reagent bincike na chromatographic da cirewa don kayan yaji, da sauransu, yana ba da ingantacciyar hanya don nazarin sinadarai da hakar kayan yaji.

Bugu da ƙari, phthalic anhydride kuma za a iya amfani da su shirya vanillin, ƙayyade fitsari sugar, shirya iri-iri synergists da antifreeze, da dai sauransu Har ila yau, yana daya daga cikin albarkatun kasa don yin polyvinyl chloride stabilizers da kuma mai kyau zabi ga karfe surface jiyya. A cikin masana'anta na roba da filastik, ana iya amfani da phthalic anhydride azaman ƙari na roba da ƙari na filastik don haɓaka aikin samfur da inganci.
