Kev Qhia:

Txoj kev tshawb fawb ntawm hluavtaws Txheej Txheem Roj Hmab Antioxidant 4020

Tam sim no, tus neeg sawv cev tiv thaiv kev laus laus 4020 yuav siv cov p-aminodiphenylamine thiab methyl isobutyl ketone ua raw khoom. Nyob rau hauv qhov siab ntawm 5-16 MPa, catalyst tooj liab yog siv rau cov tshuaj tiv thaiv hydrogen, thiab tus neeg laus laus 4020 yog tau los ntawm txoj kev kho mob tom qab. . Txawm hais tias tus txheej txheem no yog nruam, yooj yim rau kev khiav lag luam, cov catalyst yog pheej yig thiab tsis yooj yim lom, tab sis cov khoom zoo yog me ntsis neeg pluag thiab cov qoob loo yog tsawg. Tsis tas li ntawd, ib qho me me ntawm catalyst hmoov yog tswvcuab rau hauv antioxidant 4020, uas yog siv rau roj hmab los cuam tshuam kev zoo ntawm cov roj hmab khoom. Feem ntau lub teb chaws txawv teb chaws siv Pt thiab lwm yam precious hlau ua catalysts, thiab qhov zoo thiab yield yog zoo dua cov domestic ones. Tus nqi muag tau ua rau cov kev tsis txaus siab ntawm tus nqi siab loj. Tam sim no, muaj ntau yam tshuaj tiv thaiv kev laus laus 4020 tuam txhab tau tsim kev tshawb fawb ntawm cov khoom siv hlau zoo, tab sis industrialized li tsis tau raug tsa, uas yog lub ntsiab lus tseem ceeb ntawm cov laus laus 4020 synthesis. Hauv daim ntawv no, dhau ntawm qhov kev xeem me me thiab cov ntawv xeem, txoj haujlwm 4020 tau npaj los ntawm kev tshem tawm cov kabmob nrog Pt li catalyst. Ntsuam xyuas tawm 3% Pt / C los ntawm lub tuam txhab txawv teb chaws A tau txais cov khoom zoo uas peb xav tau, tom qab ntsuas kub, siab thiab faib. Piv nrog optimization, tus txheej txheem optimized yog: siab 1.5Mpa, fab kub ntawm 110-120 ° C, piv ntawm RT rau MIBK 1: 3.5 (molar ratio), cov tshuaj tiv thaiv 3 teev. Txhim kho cov teeb meem hauv kev debugging ib qho los ntawm ib qho, qhib kom tag nrho tus txheej txheem txoj kev, thiab tsim tsim tsim rau kev tsim tawm.
