Taw qhia
Antioxidant 4020, tseem hu ua N-isopropyl-N'-phenyl-o-benzodiamine (IPPD), yog ib qho tshuaj tiv thaiv antioxidant. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm Antioxidant 4020:
Zoo:
- Cov tsos: Dawb rau lub teeb xim av crystalline khoom.
- Solubility: Soluble nyob rau hauv benzene, ethanol, chloroform thiab acetone, me ntsis soluble nyob rau hauv benzene thiab petroleum ether, yuav luag insoluble nyob rau hauv dej.
Qhov hnyav molecular: 268.38 g / mol.
Siv:
- Antioxidant 4020 feem ntau yog siv los ua cov tshuaj antioxidant rau cov roj hmab sib txuas, uas tuaj yeem siv dav hauv cov khoom siv roj hmab, cov log tsheb, cov raj roj hmab, cov ntawv roj hmab thiab cov khau roj hmab thiab lwm yam kev lag luam. Nws tuaj yeem txhim kho cov cua sov, tiv thaiv oxidation thiab kev laus ntawm cov khoom siv roj hmab.
Txoj kev:
- Antioxidant 4020 feem ntau ua haujlwm nrog aniline nrog isopropanol los tsim isopropylphenol, thiab tom qab ntawd nkag mus rau qhov hloov pauv ntawm aniline thiab styrene nyob rau hauv muaj hlau lossis tooj liab catalysts thaum kawg tau txais N-isopropyl-N'-phenyl-o-benzodiamine (IPPD).
Cov ntaub ntawv kev nyab xeeb: Hnav hnab looj tes, tsom iav thiab cov khoom tiv thaiv ua pa thaum siv.
- Tsis txhob sib cuag nrog oxidants, muaj zog acids, muaj zog alkalis, thiab lwm yam, kom tsis txhob muaj kev phom sij txaus ntshai.
- Thaum lub sij hawm khaws cia thiab siv, kom deb ntawm qhov hluav taws kub thiab kub kub kom tsis txhob muaj hluav taws kub thiab tawg.
