Global - Premier Adipic Acid: Chivako Chinokosha chePolymers neMakemikari Anoshanda Zvakanaka

Hunhu hwemuviri nemakemikari

Chitarisiko uye Magadzirirwo: Adipic Acid inowanzoonekwa seupfu huchena, hwekristaro kana makristaro madiki, asina ruvara. Ine magadzirirwo akatsetseka uye haina hwema mumamiriro ezvinhu akajairwa, izvo zvinoita kuti ikwanise kushandiswa kwakasiyana-siyana kana paine chimiro chepfungwa chisina kusimba.
Kunyungudika: Inoratidza kunyungudika kuri pakati nepakati mumvura, ine inenge 1.44 g ichinyungudika mu100 mL yemvura pa25°C. Zvisinei, inonyungudika zvakanyanya muzvinhu zvinonyungudika zve organic zvakaita se ethanol, acetone, uye benzene. Maitiro aya ekunyungudika anoita kuti ikwanise kutora chikamu zvinobudirira mumhando dzakasiyana-siyana dzemakemikari uye mafomura.

Zvinhu Zvinokosha Zvemuviri: Adipic Acid ine molar mass ye146.14 g/mol. Density yayo inenge 1.36 g/cm³ pa25°C, iyo ine dense zvishoma pane mvura. Poindi yekunyunguduka kweadipic acid i152°C, zvichiratidza kuti inoshanduka kubva pachinhu chakasimba kuenda kumvura kana tembiricha yakakwira. Poindi yekufashaira inoitika pa337.5°C, kunyangwe inogona kutanga kuora isati yasvika patembiricha iyi kana yave mumhepo. Poindi yayo yekufuratira i207°C, zvichiratidza kuti inoda tembiricha yakakwira uye manyuko ekubatidza kuti ive nenjodzi yekubvira.

Kuitika kweMakemikoro: Se dicarboxylic acid, adipic acid ine mapoka maviri e carboxyl functional (-COOH), ayo anoipa reactivity yakakura yemakemikari. Inobatanidzwa nyore nyore mu esterification reactions ne alcohols, ichigadzira esters dzinoshandiswa zvakanyanya mukugadzira mapurasitiki, mafuta, uye zvinonhuwira. Pamusoro pezvo, inogona kuita ne diamines kuburikidza ne condensation polymerization kuumba polyamides, kunyanya nylon 6,6. Iyi polymerization reaction ndiyo musimboti weindasitiri ye synthetic fiber uye engineering plastics. Adipic acid inogonawo kuita reduction reactions kuumba alcohols dzinoenderana uye inogona kuita ne bases kuumba salts, inozivikanwa se adipates.

Nzvimbo dzeKushandisa

Kugadzirwa kwePolyamide (Nylon): Kushandiswa kukuru uye kwakakosha kweadipic acid kuri mukugadzira mapolyamides, kunyanya nylon 6,6. Mukuita uku, adipic acid inopindirana nehexamethylenediamine mu condensation polymerization reaction. Nylon 6,6 inobuda ipurasitiki yeinjiniya inoshanda zvakanyanya inozivikanwa nekusimba kwayo, kugara kwenguva refu, kuramba kukwesha, uye hunhu hwakanaka hwemakanika. Nylon 6,6 inoshandiswa zvakanyanya muindasitiri yemotokari yezvinhu zvakaita sezvikamu zveinjini, magiya, uye mabheringi. Ichinhu chakakoshawo muindasitiri yemachira, uko inoshandiswa kugadzira machira emhando yepamusoro ezvipfeko, makapeti, uye upholstery nekuda kwesimba rayo, kusimba, uye kugona kubata madhayi zvakanaka.

Zvigadzirwa zvepurasitiki nemafuta ekuzora: Adipic acid inoshandiswa kugadzira mapurasitiki akavakirwa pa adipate. Mapurasitiki aya anowedzerwa kuma polymers, kunyanya polyvinyl chloride (PVC), kuti awedzere kuchinjika kwawo, kugadziriswa kwawo, uye kugara kwenguva refu. Mapurasitiki eAdipate anonyanya kufarirwa mukushandiswa uko kunodiwa kuchinjika kwakaderera kwekushisa, senge mukugadzira mota dzinodzivirira waya, machubhu ekurapa, uye zvigadzirwa zvePVC zvinodzivirira kutonhora. Pamusoro pezvo, maester anobva kuadipic acid anoshandiswa semafuta mumabasa akasiyana-siyana emaindasitiri, achipa hunhu hwakanaka hwekudzivirira kupfeka uye kurwisa kukweshana, uye akakodzera kushandiswa mumainjini, magiya, uye mamwe masisitimu emakanika.

Indasitiri yeChikafu neZvinwiwa (Kushandiswa Zvisina Kunanga): Kunyange hazvo adipic acid isingadyiwe zvakananga muchikafu, inoshandiswa mukugadzira chikafu - zvinhu zvinobata chikafu uye michina yekugadzirisa chikafu. Maester ayo, kana achishandiswa mukupenda uye zvinovhara chikafu - zvinhu zvekurongedza, anobatsira kuona kuti zvigadzirwa zvekudya zvakachengeteka nekudzivirira kusvibiswa uye kuchengetedza kutsva kwechigadzirwa. Pamusoro pezvo, mapolymer akavakirwa paadipic acid anogona kushandiswa mukugadzira zvikamu zvemidziyo zvinosangana nechikafu panguva yekugadzirisa, zvakaita semabhandi ekufambisa chikafu nezvisimbiso.

Maindasitiri eMishonga neZvizoro: Muindasitiri yemishonga, adipic acid inogona kushandiswa semubatsiri mukugadzirwa kwemishonga. Inogona kushanda semushonga wekugadzirisa pH yemishonga uye suspensions, ichivimbisa kugadzikana uye kushanda kwemishonga. Muindasitiri yezvizoro, adipic acid esters inoshandiswa muzvigadzirwa zvakasiyana-siyana, zvakaita semakirimu, mafuta ekuisa mafuta, uye lipsticks, kuvandudza magadzirirwo, kuwedzera kupararira, uye kupa hunhu hwekuchenesa, zvichiita kuti ganda rinzwe rakapfava uye rakatsetseka.

Nzira dzekugadzirira

Kuoxidation yeCyclohexane: Iyi ndiyo nzira inonyanya kushandiswa muindasitiri yekugadzira adipic acid. Maitiro aya anotanga nekuoxidation yecyclohexane paine catalyst, inowanzova cobalt-based catalyst. Muchikamu chekutanga che oxidation, cyclohexane inobatana nemhepo kana oxygen kuti igadzire musanganiswa we cyclohexanol ne cyclohexanone, maitiro anozivikanwa se "KA oil" (ketone-alcohol oil). Maitiro aya anoitwa patembiricha inosvika 150 - 160°C uye kumanikidzwa kwe 1 - 1.5 MPa. Mushure mezvo, mafuta eKA anooxidation zvakare muchikamu chechipiri che reaction achishandisa nitric acid se oxidizing agent, kazhinji patembiricha ye 60 - 80°C uye kumanikidzwa kwemhepo. Iyi oxidation yechipiri yechikamu chechipiri inoshandura cyclohexanol ne cyclohexanone kuita adipic acid. Zvisinei, nzira iyi ine zvimwe zvinetso zvakatipoteredza, sezvo kushandiswa kwe nitric acid kunogadzira nitrous oxide (N₂O), gasi rine simba regreenhouse, uye kunoda kutarisirwa kwakanyatsonaka kwemvura inoyerera.

Nzira dzeBiotekinoroji: Mumakore achangopfuura, kwave nekuwedzera kufarira nzira dze biotechnology dzekugadzira adipic acid senzira inochengetedza nharaunda. Zvipukanana, zvakaita semabhakitiriya akagadziriswa majini kana mbiriso, zvinogona kushandiswa kushandura zvekudya zvinodzokororwa, zvakaita seshuga kana mafuta anobva mumiti, kuita adipic acid kuburikidza nenzira dzakasiyana-siyana dze metabolic. Semuenzaniso, mamwe mabhakitiriya anogona kugadzirwa kuti agadzire zvinhu zvepakati zvinogona kushandurwa kuita adipic acid. Kunyange zvazvo nzira idzi dze biotechnology dzichiri muchikamu chekuvandudzwa uye dzichitarisana nematambudziko ane chekuita nekugadzira uye kushanda zvakanaka kwemari, dzinopa mukana wekugadzira adipic acid isingakuvadzi nharaunda uye inogara kwenguva refu mune ramangwana.

Zvekungwaririra

Njodzi dzehutano: Adipic acid inogona kukonzera kutsamwa kweganda nemaziso kana yakabatana zvakananga. Kugara paganda kwenguva refu kana kakawanda kunogona kukonzera dermatitis, uye kana ikasangana nemaziso, inogona kukonzera kutsvuka, kurwadziwa, uye kukuvara kwe cornea. Kufema zvidimbu zveguruva zve adipic acid kunogona kutsamwisa nzira yekufema, zvichikonzera kukosora, kufemera, uye kufema zvishoma. Kudya adipic acid yakawanda kunogona kukonzera kusagadzikana kwemudumbu, kusanganisira kuda kurutsa, kurutsa, uye manyoka. Vashandi vanobata adipic acid vanofanira kupfeka midziyo yekudzivirira yakakodzera, yakaita semagurovhosi, magirazi ekuchengetedza, uye masks ekufema, kunyanya munzvimbo dzinogoneka kugadzira guruva.

Njodzi dzeMoto neKuputika: Kunyange hazvo adipic acid ine flash point yakanyanya, inogona kutsva. Kana iri upfu, inogona kugadzira musanganiswa unoputika nemhepo kana ikapararira yakawanda. Nzvimbo dzekuchengetera dzinofanira kuchengetwa kure nezvinobvira moto, uye mhepo inofefetera zvakanaka inokosha kudzivirira kuungana kweguruva. ​​Kana pakava nemoto une adipic acid, zvinhu zvinodzivirira moto zvakakodzera, zvakaita seupfu hwemakemikari akaoma kana carbon dioxide, zvinofanirwa kushandiswa.

Kukanganiswa Kwezvakatipoteredza: Asidhi yeAdipic inogara kwenguva refu munharaunda. Kana ikaburitswa mumvura, inogona kukanganiswa netupukanana nekufamba kwenguva, asi huwandu hwakawanda hunogona kukanganisa zvipenyu zvemumvura. Inogonawo kukanganisa pH yemasisitimu emvura nekuda kweasidhi yayo. Nokudaro, kutonga kwakakodzera marara uye matanho ekudzivirira zvakakosha kudzivirira kuburitswa kweasidhi yeAdipic munzvimbo isina kudzorwa. Maindasitiri anogadzira kana kushandisa adipic acid anofanirwa kutevedzera mitemo yakasimba yezvakatipoteredza kuti aderedze kukanganisa kwayo ivhu, mvura, uye mhando yemhepo.
