Synthesis method
Nws yog tau los ntawm reacting sodium ntsev ntawm 2-sulfonated benzothiazole (promoter M) nrog tert-butylamine. Maj mam ntxiv 0.75 moles ntawm tert-butylamine rau 0.5 moles ntawm sodium ntsev tov ntawm 13% promoter M. Tom qab ib nrab teev, ntxiv 0.36 moles ntawm 25% sulfuric acid tov. React ntawm 45-50℃rau 0.5 teev. Tom qab ntawd ntxiv 0.6 moles ntawm 15% hypochlorous acid sodium daws hauv 2 teev. Tom qab cov tshuaj tiv thaiv, txias, lim, ntxuav, thiab qhuav ntawm qhov kub hauv qab 50℃kom tau txais cov khoom.
Cov khoom
Grey dawb hmoov (granule) nyob rau hauv cov xim nrog iab saj thiab tsw me ntsis. Lub ntiajteb txawj nqus tshwj xeeb: 1.26--1.32, Soluble hauv ethanol, carbon tetrachloride, acetone, benzene, carbon disulfate, chloroform; Hardly soluble nyob rau hauv roj av thiab insoluble nyob rau hauv dej. Nws tsis yog hygroscopic.
Daim ntawv thov
Qhov no yog ib qho kev tshaj tawm -cov nyhuv accelerator rau cov roj hmab ntuj, roj hmab butadiene, isoprene roj hmab, styrene-butadiene roj hmab thiab cov roj hmab ntuj reclaimed roj hmab. Nws muaj kev tiv thaiv zoo heev -scorching kev ua tau zoo thiab qhov zoo ntawm lub sij hawm luv luv vulcanization, uas yog, tsis muaj scorching txaus ntshai ntawm kev khiav hauj lwm kub, tab sis cov kev txhawb zog muaj zog heev ntawm vulcanization kub, tshwj xeeb tshaj yog nyob rau hauv tej yam ntuj tso roj hmab, lub post- nyhuv yog ntau dua. Cov khoom no yuav tsum tau ua ke nrog zinc oxide thiab stearic acid, thiab tseem tuaj yeem qhib tau los ntawm thiazoles, dithiocarbamates, aldehyde amines, guanidine thiab acidic tshuaj. Cov khoom no ua rau muaj kuab paug me ntsis thiab yuav luag tsis muaj xim. Nws tuaj yeem siv los tsim lub teeb-xim lossis ci- cov khoom siv roj hmab xim, thiab feem ntau yog siv los tsim cov log tsheb, khau roj hmab, roj hmab hoses, roj hmab siv, cables thiab cov khoom lag luam dav dav, thiab lwm yam.
