N,N Dimethyl aniline P touldine (CAS: 99-97-8)

ib qho kua roj tsis muaj xim lossis daj daj nrog ntxhiab tsw ntawm qe lwj, melting point 130.31 ℃, boiling point 211.5-212.5 ℃, qhov hnyav ntawm chav tsev kub 0.9287 ~ 0.9366g / mL, refractive index 1.5360 ~ 1.5470, insoluble hauv dej, soluble hauv qee cov organic solvent, decomposes thaum raug lub teeb.

Kev Siv: Ua ib qho photoinitiator zoo rau acrylonitrile (AN) polymerization, nws yog siv dav hauv kev tsim cov khoom siv kho hniav sai, cov ntaub ntawv molding thiab acrylic anaerobic adhesives. Qhov ceev polymerization yog proportional rau 1.62 lub zog ntawm AN concentration thiab 0.62 lub zog ntawm DMT concentration. Cov khoom no feem ntau yog siv ua accelerator. Tsis tas li ntawd, nws kuj tseem siv tau ua ib qho curing accelerator rau unsaturated polyester resin thiab siv los txhim kho permeability ntawm capsule plhaub. DMT yog ib qho polymerization accelerator, xws li cov tais hniav rau cov hniav cog. Nws cov khoom tseem ceeb yog methyl methacrylate, nrog peroxide ua tus pib. Cov txheej txheem polymerization ib txwm yog kom khov los ntawm kev cua sov hauv dej npau ntawm 100 ° C rau 40 feeb. . Yog tias ntxiv 0.8% ntawm tertiary amines, xws li N, N-dimethyl-p-toluidine thiab N, N-diisopropanol-p-toluidine, lub molding tuaj yeem kho tau nws tus kheej hauv ob peb feeb ntawm chav tsev kub. Qhov no yog vim qhov tseeb tias tertiary amines Amine catalysis ua kom nrawm dua qhov kev rhuav tshem ntawm peroxide ntawm chav tsev kub, yog li ua kom nrawm dua cov txheej txheem polymerization ntawm methyl methacrylate. Ntxiv rau cov ntaub ntawv kho hniav, cov khoom siv plexiglass txawv teb chaws polymerization kuj siv cov txheej txheem catalytic self-condensation. Ntxiv 0.8% DMT thaum lub sijhawm polymerization txhawb nqa ob qho tib si polymerization thiab cross-linking. Qhov no txuag kev ua haujlwm thiab lub sijhawm, thiab tuaj yeem txhim kho qhov zoo qub. Muaj peev xwm tsim khoom siv.
