2-Methylanthraquinone (2-MAQ) 99% CAS 84-54-8

2-alkyl anthraquinone muaj txiaj ntsig zoo ntawm kev lag luam, tsis yog tsuas yog siv tshuaj lom neeg nruab nrab rau kev sib xyaw ntawm cov xim zoo nkauj, tab sis kuj yog cov khoom siv pulping zoo hauv cov txheej txheem papermaking. Nws kuj yog siv dav hauv cov tshuaj thiab tshuaj tua kab, thiab lwm yam. Ntawm 2-alkyl anthraquinone, 2-methyl anthraquinone thiab 2-ethyl anthraquinone yog cov feem ntau, thiab 2-alkyl anthraquinone tuaj yeem hloov kho raws li kev xav tau sib txawv los ua kom lub hom phiaj sib xyaw. .

Nyob rau hauv cov nqe lus ntawm dyes, 2-methylanthraquinone yog chlorinated los yog nitrated ua ntej, thiab ces muaj ntau yam anthraquinone dyes tuaj yeem ua ke. Kev txheeb cais qhia tias muaj ntau li ntau pua ntawm anthraquinone dyes.

Hauv cov txheej txheem papermaking, 2-methylanthraquinone yog cov khoom siv tau zoo heev uas tuaj yeem nkag mus rau sab hauv ntawm cov ntoo nti thiab txo qis rau 2-methylanthrahydroquinone, uas tsis ruaj khov thiab yooj yim oxidized, qhov twg lub voj voog redox hauv cov txheej txheem, cov khoom hauv ntoo chips yog oxidized, uas aggravates cov tshuaj tiv thaiv thiab txhim kho cov efficiency ntawm pulping.

Hauv cov tshuaj, alkylanthraquinones kuj muaj txiaj ntsig zoo heev. Raws li kev tshawb fawb tsis tu ncua nyob rau theem no, cov tshuaj tua kab mob, tshuaj tiv thaiv kab mob, tshuaj tua kab mob, thiab qog-tua los ntawm cov tshuaj anthraquinone tau tshawb nrhiav tsis tu ncua, thiab qee qhov ntawm lawv tau siv rau kev sib ntaus sib tua ua haujlwm.

Kev siv:

1) Siv rau kev tsim cov dyes advanced thiab intermediates;

2) Siv los ua cov tshuaj nruab nrab, thiab cov photosensitizer rau cov khoom siv hluavtaws, hluavtaws dyes, thiab photosensitive resins;

3) 2-Methylanthraquinone kuj tseem siv rau hauv smog dyes;

4) 2-Methylanthraquinone tuaj yeem siv rau hauv kev npaj muaj peev xwm bioreducible anthraquinone derivatives.
