Adipic acid yog ib qho tseem ceeb organic dibasic acid dav siv nyob rau hauv polyurethane ntau lawm, nylon 66 manufacturing, plasticizers, adhesives, lubricants, thiab lwm yam kev siv. Vim nws cov khoom siv tshuaj ruaj khov thiab cov kev xav tau dav dav, adipic acid tau dhau los ua ib qho ntawm cov khoom siv tseem ceeb hauv kev lag luam tshuaj. Hauv kev tsim khoom thiab kev thauj mus los, kev nkag siab txog nws txoj kev tsim khoom, kev cia khoom, thiab kev tiv thaiv kev nyab xeeb yog qhov tseem ceeb rau kev tswj cov khoom zoo thiab kev nyab xeeb ntawm kev ua haujlwm.
Tam sim no, feem ntau siv kev lag luam tsim qauv rau adipic acid yog cov txheej txheem cyclohexane oxidation. Hauv txoj kev tsim khoom no, cyclohexane yog thawj zaug oxidized nrog huab cua los tsim kev sib xyaw ntawm cyclohexanone thiab cyclohexanol. Cov ntaub ntawv nruab nrab no yog tom qab ntawd ntxiv oxidized, feem ntau siv nitric acid, tsim adipic acid crystals. Tom qab crystallization, cov khoom tau txais kev ua kom huv, pom, ziab, thiab ntim khoom ua ntej ua tiav kev lag luam - qib adipic acid.
Qhov kev tsim tshuab no tau txais kev pom zoo thoob ntiaj teb tau ntau xyoo vim nws txhawb nqa loj - nplai ntau lawm thiab muab cov khoom lag luam ruaj khov. Cov txheej txheem tsim nyog rau kev muab adipic acid rau kev lag luam xws li polyurethane elastomers, polyester polyols, engineering plastics, thiab hluavtaws fibers. Nyob rau hauv xyoo tas los no, nrog rau kev txhim kho ib puag ncig kev cai thiab kev txhawj xeeb txog kev ruaj ntseg, qee cov tuam txhab lag luam kuj tau pib tshawb nrhiav cov thev naus laus zis ntau lawm thiab kev txo qis emission los txhim kho cov txheej txheem kev ua tau zoo thiab txo kev cuam tshuam ib puag ncig thaum tsim khoom.
Los ntawm lub cev thiab tshuaj lom neeg sawv cev, adipic acid feem ntau yog muab los ua cov hmoov dawb crystalline nrog cov yam ntxwv ruaj khov. Nws muaj qhov melting point ntawm kwv yees li 152℃thiab tsis yooj yim nqus noo noo nyob rau hauv ib txwm cia tej yam kev mob. Adipic acid tsuas yog me ntsis soluble hauv dej tab sis dissolves yooj yim dua hauv cawv thiab qee cov kuab tshuaj organic. Txawm hais tias suav hais tias yog cov khoom siv tshuaj lom neeg ruaj khov, adipic acid tseem kub hnyiab tau ntawm qhov kub thiab txias, yog li yuav tsum tau ceev faj kom tsim nyog thaum khaws cia thiab thauj mus los.
Rau kev ntim khoom, adipic acid feem ntau tau ntim rau hauv cov hnab polypropylene woven nrog cov hnab yas sab hauv, feem ntau hauv 25kg ntim units. Loj -cov neeg siv khoom lag luam ntim kuj tseem tuaj yeem yuav lub hnab ntim jumbo rau kev thauj mus los ntau thiab khaws cia. Kev sib khi kom zoo thaum lub sijhawm ntim khoom thiab xa khoom tuaj yeem pab txo qis cov dej noo thiab tiv thaiv cov khoom poob thaum tuav.
Raws li cov kev cai ntawm kev lag luam ib txwm muaj, adipic acid feem ntau yog thauj khoom raws li cov khoom siv tshuaj es tsis yog cov khoom siv phom sij heev. Txawm li cas los xij, kev thauj mus los tseem yuav tsum ua raws li cov lus qhia dav dav txog kev siv tshuaj, suav nrog kev tiv thaiv los ntawm nag, cov av noo siab, thiab lub cev puas tsuaj rau cov ntim khoom thaum thauj khoom thiab thauj khoom.
