Kev Tshawb Fawb Ntawm Lub Tshuab Tshiab Rinse Catalytic Synthesis Ntawm Antioxidant SP

(1) antioxidant SP alkylation synthesis reactive xaiv macroporous muaj zog acid cation txauv resin ua ib tus catalyst tsim nyog, tus nqi kwv yees li 7% mus rau 9% ntawm phenol, qhov sib xyaw ua rau sib luag synthesis: kub 100 ~ 115 ℃, styrene Nrog cov hniav sib txawv ntawm phenol 2.05 ~ 2.20: 1, cov tshuaj tiv thaiv lub sij hawm 2.15 ~ 2.45 h, cov khoom tawm los yog ntau dua 95%, xim xim zoo.
Muaj pes tsawg tus ntawm 2,1: 1, tus nqi tshuaj (phenol) 8%, cov tshuaj tiv thaiv kom txias dua 105 ℃, cov tshuaj tiv thaiv lub sij hawm 2.5 h hauv cov xwm txheej ntawm cov khoom muag 97%, qhov muag pom ntawm lub teeb daj pob tshab, ceev, tshauv, Ntsuas khoom zoo kev xav tau.
(3) antioxidant SP yog ib qho uas tsis yog-polluting roj hmab antioxidant, muaj kev ua haujlwm siab, tsis muaj tshuaj lom, tsawg tus nqi, thiab lwm yam., Uas yog siv rau styrene butadiene roj hmab thiab chloroprene roj hmab stabilizer, polyolefin thiab POM Oxidising agent. Cov khoom nyob rau hauv daim ntawv thov ntawm styrene butadiene roj hmab kom ua tau zoo dua.
