Phthalic Anhydride, Yakagadzirira Kutumirwa ~

Application:

Kutanga, phthalic anhydride inoita basa rakakosha mumunda wekugadzira zvinodhaka. Icho chinhu chinokosha chekugadzirwa kwemishonga inorwisa-kupisa, mishonga yemimba, mishonga inorwisa mabhakitiriya, anticancer mishonga nemimwe mishonga. Pamusoro pezvo, phthalic anhydride zvakare inotungamira kugadzirira kweakasiyana mahomoni echirimwa akadai sekukura kwehomoni uye auxin, iyo yakakosha zvikuru mukusimudzira kukura kwezvirimwa uye kuwedzera goho rezvirimwa.

Kechipiri, phthalic anhydride inoshandiswawo zvakanyanya muindasitiri yedhayi nekunhuhwirira. Sechinhu chepakati chedhayi nezvinonhuhwira, phthalic anhydride inoshandiswa kugadzira zvinonhuwira, pigment, synthetic fiber dhayi, nezvimwewo. Mamiriro ayo emakemikari ega ega anoita kuti isadzorereke muminda iyi, ichiwedzera mavara akapfuma uye hwema kuhupenyu hwevanhu.

Pamusoro pezvo, phthalic anhydride inoitawo basa rakakosha mukugadzira mapurasitiki nerabha. Chinhu chakakosha mbishi kugadzirwa kwepolymer komisheni senge polyphenylene ether, polyamide, uye polyimide. Aya makomisheni epolymer ane zvimiro zvakanaka zvemuviri uye kugadzikana kwemakemikari, uye anoshandiswa zvakanyanya mumotokari, zvemagetsi, kuvaka uye mamwe minda, achipa rutsigiro rwakasimba mukusimudzira nzanga yazvino.

Mumunda weorganic synthesis, phthalic anhydride ine huwandu hwakawanda hwekushandisa. Inogona kushandiswa carbonylation, propylene oxidation, kugadzirira activated carbon esters, yakaoma hydrogenation, aldehyde uye ketone esterification, nitric acid uye alkaline oxidation. Mune inorganic synthesis, phthalic anhydride inogona kushandiswa kugadzira ammonium munyu, uye inogona zvakare kushandiswa seyakanyanya polymerization mumiriri wekugadzira mhangura zinc sulfide. Aya maitiro ekugadzira anopa hupfumi hwezvinhu hwaro hwekusimudzira indasitiri yemakemikari.

Pamusoro pezvo, phthalic anhydride ine zvakare yakakosha mashandisirwo mumunda wemakemikari akanaka. Inogona kushandiswa kune akasiyana siyana ekuparadzanisa crystallization uye catalytic reactions, uye inogona zvakare kushandiswa kugadzirira uye kuparadzira tekinoroji yeakasiyana inorganic calcium sulfur polymers. Mukugadzirisa zvicherwa, phthalic anhydride inogona kushandiswa kugadzira zvicherwa zveore deposits kuvandudza kushanda kwemigodhi uye mhando yeore. Pamusoro pezvo, phthalic anhydride inogona zvakare kushandiswa seyakabikwa yezvipembenene nemishonga yezvipembenene, ichiita basa rakakosha mukuona kukura kwezvirimwa uye kuwedzera goho.

Mukugadzirwa kwemaindasitiri, phthalic anhydride inonyanya kushandiswa sechinhu chinonyungudutsa uye chinobvisa. Nekuda kwekudzika kwayo kubikira uye kunyungudika kwakanyanya, phthalic anhydride inoshandiswa zvakanyanya mupetroleum yekunatsa uye petrochemical maindasitiri sechinhu chinopaza mbishi. Panguva imwecheteyo, inogonawo kushandiswa se chromatographic analysis reagent uye inobvisa zvinonhuwira, nezvimwewo, ichipa nzira inoshanda yekuongorora kemikari uye kubvisa zvinonhuwira.

Mukuwedzera, phthalic anhydride inogonawo kushandiswa kugadzirira vanillin, kuona shuga yeweti, kugadzirira zvakasiyana-siyana zve synergists uye antifreeze, nezvimwewo. Ichowo chimwe chezvinhu zvakasvibirira zvekugadzira polyvinyl chloride stabilizers uye sarudzo yakanaka yekurapa kwesimbi. Mukugadzira rabha nepurasitiki, phthalic anhydride inogona kushandiswa seyekuwedzera rabha uye yepurasitiki yekuwedzera kuvandudza kuita kwechigadzirwa uye kunaka.
