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

uketshezi olunamafutha olungenambala noma oluphuzi olukhanyayo olunephunga lamaqanda abolile, indawo encibilikayo engu-130.31 ℃, indawo ebilayo engu-211.5-212.5 ℃, isisindo ekamelweni lokushisa 0.9287 ~ 0.9366g/mL, inkomba ye-refractive 1.5360 ~ 1.5470, amanzi athile angancibiliki. I-solvent ye-organic, iyabola lapho ibekwe ekukhanyeni.

Ukusetshenziswa: Njenge-photoinitiator ephumelelayo ye-acrylonitrile (AN) polymerization, isetshenziswa kabanzi ekukhiqizeni izinto zamazinyo ezizibekela yona ngokushesha, izinto zokubumba kanye nezinamatheliso ze-acrylic anaerobic. Isivinini se-polymerization silingana namandla angu-1.62 wokugxiliswa kwe-AN kanye namandla angu-0.62 wokugxiliswa kwe-DMT. Lo mkhiqizo uvame ukusetshenziswa njenge-accelerator. Ngaphezu kwalokho, ingasetshenziswa futhi njenge-accelerator elaphayo ye-polyester resin engagcwele futhi isetshenziselwe ukuthuthukisa ukufinyeleleka kwamagobolondo we-capsule. I-DMT iyisisheshi se-polymerization, njengamathreyi amazinyo okufakelwa kwamazinyo. Ingxenye yayo eyinhloko i-methyl methacrylate, ene-peroxide njengesiqalo. Inqubo evamile ye-polymerization iwukuqina ngokufudumeza emanzini abilayo ku-100 ° C imizuzu engu-40. . Uma u-0.8% wama-amine emfundo ephakeme engezwa, njenge-N,N-dimethyl-p-toluidine kanye ne-N,N-disopropanol-p-toluidine, ukubumba kungelapheka ngokwako emizuzwini embalwa ezingeni lokushisa legumbi. Lokhu kungenxa yokuthi i-tertiary amines Amine catalysis isheshisa ukubola kwe-peroxide ekamelweni lokushisa, ngaleyo ndlela isheshisa inqubo ye-polymerization ye-methyl methacrylate. Ngokungeziwe ezintweni zamazinyo, i-plexiglass polymerization yangaphandle iphinde isebenzise inqubo yoku-condensation eyi-catalytic. Ukwengeza u-0.8% we-DMT ngesikhathi se-polymerization kukhuthaza kokubili ukwenziwa kwe-polymerization nokuxhumanisa. Lokhu konga umsebenzi nesikhathi, futhi kungathuthukisa kakhulu izinga lokuqala. Amandla okukhiqiza izisetshenziswa.
