2ME; 2-Mercaptoethanol; β-Mercaptoethanol, 2-Hydroxyethanethiol

Kev Piav Qhia Luv:

2-Mercaptoethanol, tseem hu ua β-mercaptoethanol, 2-hydroxyethanethiol, thiab 2-ME, yog ib qho organic compound nrog cov mis molecular C2H6OS. Nws zoo li cov kua tsis muaj xim, pob tshab thiab muaj ntxhiab tsw qab heev. Yooj yim yaj hauv dej thiab sib xyaw nrog ethanol, ether thiab benzene hauv txhua qhov sib piv. 2-Mercaptoethanol yog ib hom tshuaj lom neeg tseem ceeb, uas tuaj yeem siv dav hauv cov tshuaj tua kab, tshuaj, xim, tshuaj lom neeg, roj hmab, yas, ntaub thiab lwm yam teb.

2-Mercaptoethanol muaj ntau yam kev siv. Nws tuaj yeem siv ua cov organic synthesis intermediate hauv cov xwm txheej tsim tshuaj tua kab xws li tshuaj tua kab thiab tshuaj tua kab; nws tuaj yeem siv ua cov khoom siv pabcuam thiab cov khoom siv photosensitive hauv roj hmab, textile, yas, thiab txheej txheem tsim khoom; nws tuaj yeem siv ua telomer Agents, heat stabilizers, thiab cross-linking agents siv rau hauv kev tsim cov khoom siv polymer xws li polyvinyl chloride, polyacrylonitrile, polystyrene, thiab polyacrylate; tuaj yeem siv ua antioxidants hauv kev sim tshuaj lom neeg; tuaj yeem siv ua cov khoom siv raw nrog aldehydes lossis Ketone reaction siv rau hauv qhov xwm txheej tsim khoom ntawm oxygen-sulfur heterocyclic compounds.

Cov kua dej uas yooj yim hlawv, lom yog tias nqos, tuag taus thaum kov daim tawv nqaij, ua rau khaus tawv nqaij, khaus qhov muag heev, yuav ua rau puas tsuaj rau cov kabmob, kev raug tshuaj mus sij hawm ntev lossis ntau zaus yuav ua rau puas tsuaj rau cov kabmob, kev lom rau cov tsiaj hauv dej tsis muaj cov teebmeem mus sij hawm ntev.

[Kev Ceeb Toom]
● Cov thawv yuav tsum kaw kom nruj thiab khaws cia kom tsis txhob muaj pa. Thaum lub sijhawm thauj khoom, tshem tawm thiab thauj mus los, tsis txhob poob thiab sib tsoo nrog cov khoom tawv thiab ntse.
● Khaws cia kom deb ntawm cov nplaim taws qhib, cov chaw kub, thiab cov tshuaj oxidants.
● Txhim kho qhov cua nkag thaum lub sijhawm ua haujlwm thiab hnav cov hnab looj tes latex uas tiv taus acid thiab alkali thiab cov ntaub thaiv roj uas lim tau nws tus kheej.
● Tsis txhob kom raug qhov muag thiab daim tawv nqaij.
