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

Cov kua tsis muaj xim lossis lub teeb daj oily nrog tsis hnov ​​​​tsw ntawm cov qe lwj, melting point 130.31 ℃, boiling point 211.5-212.5 ℃, hnyav ntawm chav tsev kub 0.9287 ~ 0.9366g / mL, refractive index 1.5360 ~ 1.5470, insoluble hauv dej, Organic hnyav, decomposes thaum raug rau lub teeb.

Kev Siv: Raws li ib qho zoo photoinitiator rau acrylonitrile (AN) polymerization, nws yog dav siv hauv kev tsim cov khoom siv kho hniav ceev ceev, cov ntaub ntawv molding thiab acrylic anaerobic adhesives. Lub polymerization ceev 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 los ua tus accelerator. Tsis tas li ntawd, nws tseem tuaj yeem siv los ua cov tshuaj tua kab mob rau cov khoom siv tsis zoo polyester thiab siv los txhim kho cov permeability ntawm cov tshuaj capsule plhaub. DMT yog cov khoom siv hluav taws xob polymerization, xws li cov tais diav rau kev cog hniav. Nws cov khoom tseem ceeb yog methyl methacrylate, nrog peroxide ua tus pib. Cov txheej txheem polymerization ib txwm yog ua kom muaj zog los ntawm cua sov hauv dej kub ntawm 100 ° C rau 40 feeb. . Yog tias 0.8% ntawm tertiary amines ntxiv, xws li N, N-dimethyl-p-toluidine thiab N, N-diisopropanol-p-toluidine, molding tuaj yeem kho los ntawm nws tus kheej li ob peb feeb ntawm chav tsev kub. Qhov no yog vim lub fact tias tertiary amines Amine catalysis accelerates lub decomposition ntawm peroxide nyob rau hauv chav tsev kub, yog li accelerating lub polymerization txheej txheem ntawm methyl methacrylate. Ntxiv nrog rau cov ntaub ntawv kho hniav, txawv teb chaws plexiglass polymerization kuj siv cov txheej txheem catalytic tus kheej condensation. Ntxiv 0.8% DMT thaum lub sij hawm polymerization txhawb ob qho tib si polymerization thiab cross-linking. Qhov no txuag kev ua haujlwm thiab lub sijhawm, thiab tuaj yeem txhim kho tus thawj zoo. Cov cuab yeej tsim muaj peev xwm.
