Umenzi Ixabiso Elihle Dimethylbenzylamine (BDMA) CAS:103-83-3

Ixabiso Elihle Lomenzi I-Dimethylbenzylamine (BDMA) CAS:103-83-3 Umfanekiso Obonakalayo

inkcazo emfutshane:

I-Dimethylbenzylamine (BDMA) lulwelo olungenambala ukuya koluphuzi olukhanyayo olunevumba elimnandi. Luncinci kancinci kunamanzi kwaye lunyibilika kancinci emanzini. I-Flash point malunga ne-140°F. Iyakonakalisa ulusu, amehlo kunye neenwebu ze-mucous. Inobungozi kancinci ngokuyiginya, ukufunxa ulusu kunye nokuphefumla. Isetyenziswa ekwenzeni izincamathelisi kunye nezinye iikhemikhali.

Izicelo ze-BDMA

I-Intermediate, ingakumbi kwiikhompawundi ze-ammonium ze-quaternary; i-dehydrohalogenating catalyst; i-corrosion inhibitor; i-acid neutralizer; iikhompawundi ze-potting; izincamathelisi; i-cellulose modifier.
I-N,N-Dimethylbenzylamine isetyenziswa ekulungiseleleni i-bis[(N,N-dimethylamino)benzyl] selenide. Isebenza njenge-catalyst kwi-reaction yokuphilisa yeefomyula ze-diglycidyl ether ze-bisphenol A kunye ne-tetrahydrophthalic anhydride. Ingena kwi-directed ortho metalation kunye ne-butyl lithium. Isabela kwi-methyl iodide ukuze ifumane ityuwa ye-ammonium, esetyenziswa njenge-phase transfer catalysts. Ngaphezu koko, isetyenziswa njenge-catalyst yokwenziwa kwe-polyurethane foams kunye ne-epoxy resins.
I-N,N-Dimethylbenzylmine yasetyenziswa ekuhlanganiseni i-bis[(N,N-dimethylamino)benzyl] selenide. Isetyenziswe njenge-catalyst ngexesha lokulungisa i-formulations ye-diglycidyl ether ye-bisphenol A kunye ne-tetrahydrophthalic anhydride.

Ukulungiselela: 25% iDimethylamine yamanzi, 1088 grams

I-Benzyl Chloride, iigram ezili-126.6

Kwisixhobo soMzekelo 1, i-benzyl chloride yongezwa nge-dropwise kwixesha leeyure ezimbini kwi-amine (umlinganiselo we-molar 1 ukuya ku-6) ngesantya esaneleyo sokugcina ubushushu bungaphantsi kwama-40°C. Ukuxukuxa kwaqhubeka kubushushu begumbi kangangeyure eyongezelelweyo ukuqinisekisa ukugqitywa kwempendulo echazwe yi-equation engezantsi.

Emva koko umxube we-reaction wapholiswa kwi-separatory funnel ngelixa umi efrijini egcinwe kwi-5°C. waza wahlulwa waba ziileya ezimbini. Umaleko ongaphezulu weoyile, onobunzima obuyi-111.5g, wasuswa waza wanyibilikiswa ngomphunga de kungabikho nxalenye ye-oleaginous ebonwayo kwi-distillate njengoko yayivela. I-distillate ekrwada yafunyaniswa ine-103.5g ye-N,N-dimethylbenzylamine (76.1% yethiyori), i-3.3g ye-dimethylamine kwaye ayinazo iityuwa ze-quaternary. I-dimethylamine yanyibilikiswa ngaphantsi kwama-29°C phantsi koxinzelelo lomoya oluvela kwi-N,N-dimethylbenzylamine (bp 82°C/18mmHg).
