4,4'-Oxydianiline nrog CAS 101-80-4 yog dab tsi?

4,4-diaminodiphenyl Ether (4'-ODA) CAS 101-80-4,4,4'-oxydianiline yog ib qho tseem ceeb aromatic diamine organic compound. Vim muaj ob pawg amino (-NH₂) thiab ib qho ether bond (-O-) hauv nws lub molecule, 4,4'-DPE muaj kev ua haujlwm zoo heev thiab kev tiv taus cua sov thiab yog ib qho tseem ceeb monomer rau kev tsim cov khoom siv polymer ua tau zoo.

Ua ib yam khoom siv tshwj xeeb hauv kev tsim kho, polyimide muaj qhov zoo ntawm kev tiv taus kub siab, tiv taus hluav taws xob thiab lub zog siab. Diaminodiphenyl ether siv rau hauv cov yeeb yaj kiab, txheej txheej, fibers, aerospace, kev lag luam hluav taws xob thiab hluav taws xob, cov yas ua npuas ncauj thiab photoresists. 4,4'-Diaminodiphenyl ether yog ib qho ntawm cov khoom siv raw tseem ceeb. Tib lub sijhawm, 4,4'-diaminodiphenyl ether kuj tseem siv tau los tsim cov neeg sawv cev sib txuas, thiab siv dav los hloov cov carcinogenic benzidine los tsim cov xim azo thiab cov xim reactive. Yog li ntawd, 4,4'-diaminodiphenyl ether yog ib qho nruab nrab nrog tus nqi ntxiv siab.

Daim Ntawv Thov

1. 4'-ODA yog ib qho ntawm cov khoom siv tseem ceeb rau cov yas tsim tshwj xeeb tshiab xws li polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid thiab lwm yam khoom siv kub siab;
2. 4'-ODA kuj tseem raug tsim ua ke. Cov khoom siv raw ntawm 3,3', 4,4'-tetraaminodiphenyl ether, uas yog lub monomer tseem ceeb rau kev npaj cov khoom siv polymer uas tiv taus cua sov heterocyclic aromatic.
3. 4,4'-DPE kuj tseem siv ua cov khoom siv raw thiab tus neeg sawv cev sib txuas rau kev ua haujlwm siab-resistant epoxy resin, polyurethane thiab lwm yam polymers hluavtaws.
4. 4,4'-DPE kuj tseem siv los hloov cov carcinogenic benzidine hauv kev tsim cov azo dyes, reactive dyes thiab cov tshuaj tsw qab. Tam sim no, siv diaminodiphenyl ether ua cov khoom siv raw, cov xim ncaj qha ntawm ntau qib xim xws li liab ci, liab ci, xuab zeb liab, daj-xim av, ntsuab, grey, xiav, txiv kab ntxwv ci thiab dub tau tsim, uas tuaj yeem siv rau txhob lo lo ntxhuav, ntaub plaub, paj rwb, Kev zas xim ntawm hemp thiab lwm yam ntaub zoo dua li benzidine dyes hauv cov nqe lus ntawm xim ceev thiab qhov nrawm ntawm kev qaug zog.
