Umvelisi ofanelekileyo kwixabiso le-dimyethylzzzzzle

Inkcazo emfutshane:

I-DimyethylblenLamine (i-BDMA) ingenabala ukuba ingulwelo oluzikhanyisa nge-odomatic evuthayo. Imbonakalo kancinane kancinci kunamanzi kwaye inyibilike kancinci emanzini. I-Flash inqaku malunga ne-140 ° F. Phawula ulusu, amehlo kunye ne-mucous membrane. Ityhefu kancinane ngokungenela, ukufunxa kwesikhumba kunye nokuphefumla. Isetyenziswe ekwenzeni umnyango kunye nezinye iichemicals.

I-CAS: 103-83-3

Izicelo ze-BDMA

Phakathi, ngakumbi kwii-ammon ammonium computer; I-Deghroallyty Catallyst; I-Interrosion ithinga; ukungathathi cala i-acid; i-Porting; Ababulala; I-seluplose modifier.
N, i-n-dimyethylzbenlamine isetyenziswa kumalungiselelo e-bis [(n, n-dimthylamini) i-benzyl]. Isebenza njengeyona nto ibaluleke kakhulu kwi-sutations yokwenziwa kwe-diglycidyl ekutyuntshekeni kwe-bisphenol and tetrarahdrophthayical anehydride. Ihlala ikhokelele i-ortho yokuya kwi-Ortho ukuba i-butyl lithium. Inika ingxelo nge-methyl ionide ukufumana ityiwa ye-Ammonium, esetyenziswa njengokudlulisela kwinqanaba lokudlulisela. Ngaphaya koko, isetyenziswa njengeyona nto iphambili ekuqulunqweni kwe-Polyururthane Foures kunye ne-Epoxy Revins.
N, i-n-dimyethylzbenlamine yayisetyenziswa kwi-synthesis ye-bis [(n, n-dimyethylamini) i-benzylide. Isetyenziswe njengokuthambisa ngexesha lokunyanga ukucamukiswa kwe-DiclyCidyl Ether ye-bisphenol and tetrarahdrophthayical andhydride.

Ukulungiselela: Iipesenti ezingama-25 ze-dimyethylamine, iigram ezingama-1088

I-Benzyl Chloride, i-126.6 iigram

Kwisixhobo somzekelo woku-1, i-benzyl chloride yongezwa ngaphezulu kwexesha leeyure ezimbini ukuya kwi-amine (i-molar ratio 1 ukuya kwi-6) kwi-6 ° C. Ukuvuselela kwaqhubeka kubushushu begumbi ngeyure eyongezelelweyo yokufumana ukugqitywa kwempendulo echazwe yi-equation ngezantsi.

Emva koko umxube wokuphendula wapholwa kwi-fungratory full ngelixa emi kwifriji egcinwe kwi-5 ° C. kwaye yahlulwe sababini. I-olite ephezulu ye-oill, enobunzima obuyi-111.5g, isuswe kwaye inyibilikisiwe de kubekho i-Oleaginous ye-Oleaginous yaqwalaselwa kwi-rightte njengoko idlulile. I-CREATE YOBUCHULE ifunyenwe iqulethe i-103.5G ye-N, n-dimyethylzzzzle (76.1% yethiyori), i-3.3g ye-DIMETHyLAmine kwaye ayikho i-duatheethylamine kwaye ayikho i-duatheethylamine kwaye ayikho i-duatheethylamine kwaye ayikho i-duatheethylamine kwaye ayikho i-duatheethylamine kwaye ayikho i-duatheethylamine kwaye ayikho i-duathylamine kwaye ayikho i-duathylamine kwaye ayikho i-duathylamine kwaye ayikho i-duathylamine kwaye ayikho iityuwa. I-DIMETHyLAMLE ichithwe ngaphantsi kwe-29 ° C phantsi kwengcinezelo ye-atmosmosfic ivela kwi-N, i-N-Dimethylzzblemine (BP 82 ° C / 18mmhg).
