Kev Qhia:

Antiager 4020 Antiager 4020, cov npe tshuaj: N - (1, 3 - dimethyl butyl) - N - phenyl para-phenylene diamine, cov khoom yog ib yam ntawm cov roj hmab loj tshaj plaws ntawm cov thoob ntiaj teb tire ntau hom, Cov tawv ntoo ua haujlwm zoo, qhov laus ntawm cov cua kub, huab cua kuj muaj kev tiv thaiv zoo, thiab muaj kev txav ntawm cov hlau, siv roj hmab, butadiene rubber, styrene-butadiene roj hmab, nitrile roj hmab thiab neoprene, thiab paraffin (tshwj xeeb tshaj yog nrog rau kev sib tov ntawm branched saw wax thiab microcrystalline wax thiab siv, yuav txhim khu cov nyhuv ntawm kev tiv thaiv.Thaum siv nyob rau hauv dynamic thiab static kev nyuaj siab thiab hloov deformation ntawm roj hmab khoom, tyre khaubncaws sab nraud, puab tub thiab conveyor txoj siv thiab lwm yam kev tiv thaiv system ntawm qhov zoo tshaj plaws kev xaiv ntawm ntau yam, piv nrog tus laus Agent NA, dej siv zog pub zoo, muaj peev xwm ua tau ntev tiv thaiv effect.The synthesis ntawm antioxidant 4020 yog raws li lub catalytic hydro genation cov tshuaj tiv thaiv ntawm 4-aminodiphenylamine thiab methyl isobutyl ketone tom qab condensation nyob rau hauv lub siab ntawm 5 ~ 16MPa. Cov tshuaj tiv thaiv yog tau los ntawm refining, separating thiab granulating.Copper feem ntau yog siv raws li cov catalyst rau catalytic hydrogenation ntawm domestic anti aging agent 4020, thaum feem ntau txawv teb chaws zoo li hlau xws li Pt yog siv raws li cov catalyst. Yog li ntawd, qhov zoo thiab tawm los ntawm txawv teb chaws cov khoom yog zoo tshaj li domestic khoom. Tam sim no, ntau domestic manufacturers tseem accelerating cov kev tshawb nrhiav kev tshawb ntawm Pt catalyst, tab sis nws tseem tsis tau industrialized.Ntos ntxiv, tus yuam sij rau cov khoom thiab kev loj hlob ntawm aging Agent 4020 yog 4-aminodiphenylamine thiab methyl isobutyl ketone li raw cov ntaub ntawv. Tus synthesis ntawm 4-aminodiphenylamine yuav tsum tau txais txoj kev ntshiab nitrobenzene sai li sai tau los hloov cov formylaniline uas siv p-nitrochlorobenzene li raw cov ntaub ntawv, uas tuaj yeem txo qhov raug nqi ntawm 4-aminodiphenylamine.Nws yog, methyl isobutyl ketone tsis yog tsim nyob rau hauv Suav teb, thiab qhov kev thov yog txhua yam nyob ntawm cov tuaj txawv teb chaws tuaj. Nyob rau xyoo 2004, cov kev tuaj txawv teb chaws tuaj txog 36900t. Nyob rau hauv lub neej yav tom ntej, Tuam Tshoj yuav xav txog kev qhia tawm txawv teb chaws advanced acetone ib-theem hydrogenation txoj kev los tsim kom muaj cov kab tsim methyl isobutyl ketone nrog ib xyoo zus ntawm 30,000 t.
