Antioxidant 1520

AO1520

Antioxidant 1520 (2, 4-bis (n-octylthiomethylene, thenhologen Radicals, thiab lwm yam, los tiv thaiv oxygen, cua sov, lub teeb lossis High-zog hluav taws xob kev puas tsuaj rau cov organic teeb meem. Tshwj xeeb, antioxidant 1520 tuaj yeem siv los tiv thaiv oxidleatures nyob rau hauv isoprene roj hmab, kom tiv thaiv kev ua haujlwm ntawm cov khoom lag luam STYRENE, txhawm rau tiv thaiv cov gel tsim hauv Elastomers thiab ntiag tug sib xyaw xim hloov thaum lub sijhawm khaws cia thiab kev thauj mus los.

Daim ntawv thov

Antioxidant 1520 yog cov roj ntsha siab tshiab ua kua tshuaj tiv thaiv roj hmab, cov roj hmab ua haujlwm me me, tuaj yeem txhim kho qhov ruaj khov roj hmab, tuaj yeem txhim kho kev ruaj khov ntawm plastics lossis hluavtaws plastics. Nws yog antioxidant, uas paub qhov kev hloov pauv ntawm cov khoom lag luam roj hmab los ntawm universal rau ntsuab.

Synthesis txoj kev

Tam sim no, tus txheej txheem sib sau ntawm antioxidant 1520 feem ntau yog Mantylphenan, N-Methylfphenan, formaldehyde lossis parnichdede tau los ntawm Mannich cov tshuaj tiv thaiv.

Cov txheej txheem sab saum toj synthesis suav nrog ob txoj kev khiav hauv kev ua haujlwm tiag tiag, thiab kev sib cais ntawm cov tshuaj tiv thaiv methylat 1520, thiab tom qab ntawd kev sib cais thiab kev ua kom huv ntawm cov khoom, tseem hu ua tus ob-kauj ruam txoj kev. Cov ntaub ntawv raug suav nrog US38328, EP428973A1, US5116894, thiab cov txiaj ntsig thiab cov txiaj ntsig los yog tsawg, uas tsis haum rau kev lag luam lag luam.

Ib qho kev tsim nyog ntawm cov hluavtaws ntawm antioxidant 1520 muaj cov kauj ruam hauv qab no:

1) o-cresol, n-octylmerkapan, formaldehyde, diethanmamine thiab cov kuab tshuaj tau ntxiv rau kho cov pH rau 1-5 rau reflux cov tshuaj tiv thaiv;

2) Cua txias thiab sawv kom nruj, tso cov theem dej qis los ntawm qhov hluav taws xob qis ntawm cov reactur, tom qab ntawd ntxiv, thiab tom qab ntawd rov ua kom cov tshuaj tiv thaiv;

3) Txias, lim kom tshem tawm cov teeb meem insoluble, ntxiv cov txiaj ntsig tsim nyog ntawm formic acid thiab rheat rau 30-60 ℃, nplawm;

4) Tom qab ntxuav nrog dej, nqus distillation, kom qhuav, npaj txhij.
