Phthalic Anhydride 99%, A shirye don jigilar kaya ~

Aikace-aikace:

Da farko, phthalic anhydride yana taka muhimmiyar rawa a fannin kera magunguna. Yana da muhimmiyar hanya wajen kera magungunan hana kumburi, magungunan ciki, maganin rigakafi, magungunan hana ciwon daji da sauran magunguna. Bugu da ƙari, phthalic anhydride shi ma wani abu ne da ke ba da damar shirya nau'ikan hormones na shuka kamar hormone girma da auxin, wanda hakan yana da matuƙar muhimmanci wajen haɓaka girman shuka da kuma ƙara yawan amfanin gona.

Abu na biyu, ana amfani da phthalic anhydride sosai a masana'antar rini da ƙamshi. A matsayin matsakaici ga rini da kayan ƙanshi, ana amfani da phthalic anhydride don yin kayan ƙanshi, launuka, rini na zare na roba, da sauransu. Abubuwan da ke tattare da shi na musamman sun sa ba za a iya maye gurbinsa a waɗannan fannoni ba, suna ƙara launuka masu kyau da ƙamshi ga rayuwar mutane.

Bugu da ƙari, phthalic anhydride yana taka muhimmiyar rawa wajen ƙera robobi da roba. Yana da muhimmin abu wajen ƙera mahaɗan polymer kamar polyphenylene ether, polyamide, da polyimide. Waɗannan mahaɗan polymer suna da kyawawan halaye na zahiri da kwanciyar hankali na sinadarai, kuma ana amfani da su sosai a cikin motoci, kayan lantarki, gini da sauran fannoni, suna ba da tallafi mai ƙarfi ga ci gaban al'umma ta zamani.

A fannin haɗakar sinadarai ta halitta, phthalic anhydride yana da nau'ikan aikace-aikace iri-iri. Ana iya amfani da shi don carbonylation, oxidation na propylene, shirya carbon esters da aka kunna, hydrogenation busasshe, aldehyde da ketone esterification, nitric acid da alkaline oxidation. A cikin haɗakar sinadarai ta halitta, ana iya amfani da phthalic anhydride don haɗa gishirin ammonium, kuma ana iya amfani da shi azaman babban wakilin polymerization don haɗa sinadarin zinc na jan ƙarfe. Waɗannan halayen roba suna ba da tushen kayan aiki mai yawa don haɓaka masana'antar sinadarai.

Bugu da ƙari, phthalic anhydride yana da amfani mai mahimmanci a fannin sinadarai masu kyau. Ana iya amfani da shi don yin amfani da nau'ikan crystallization daban-daban na rabuwa da kuma halayen catalytic, kuma ana iya amfani da shi don shirya da watsa fasahar watsawa na nau'ikan polymers na calcium sulfur marasa tsari. A cikin sarrafa haƙar ma'adinai, ana iya amfani da phthalic anhydride don sarrafa ma'adanai na ma'adanai don inganta ingancin haƙar ma'adinai da ingancin ma'adinai. Bugu da ƙari, ana iya amfani da phthalic anhydride a matsayin kayan aiki na kayan kwari da magungunan kashe ƙwari, yana taka muhimmiyar rawa wajen tabbatar da ci gaban amfanin gona da haɓaka yawan amfanin gona.

A fannin samar da phthalic anhydride, galibi ana amfani da shi azaman mai narkewa da kuma cirewa. Saboda ƙarancin tafasa da kuma yawan narkewar sa, ana amfani da phthalic anhydride sosai a masana'antar tace mai da kuma masana'antar petrochemical a matsayin kayan da aka ƙera. A lokaci guda, ana iya amfani da shi azaman mai nazarin chromatographic da kuma mai cirewa don kayan ƙanshi, da sauransu, wanda ke samar da ingantacciyar hanyar nazarin sinadarai da cire kayan ƙanshi.

Bugu da ƙari, ana iya amfani da phthalic anhydride don shirya vanillin, tantance sukarin fitsari, shirya nau'ikan masu haɗa sinadarai da hana daskarewa, da sauransu. Hakanan yana ɗaya daga cikin kayan da ake amfani da su don yin polyvinyl chloride masu daidaita sinadarai kuma zaɓi ne mai kyau don maganin saman ƙarfe. A cikin kera roba da filastik, ana iya amfani da phthalic anhydride azaman ƙarin roba da ƙari na filastik don inganta aikin samfur da inganci.
