Umkhiqizi Intengo Enhle I-Dimethylbenzylamine (BDMA) I-CAS:103-83-3

Intengo Enhle Yomkhiqizi I-Dimethylbenzylamine (BDMA) CAS:103-83-3 Isithombe Esifakiwe

incazelo emfushane:

I-Dimethylbenzylamine (BDMA) iwuketshezi oluphuzi olungenambala noma olukhanyayo olunephunga elimnandi. Luncane kancane kunamanzi futhi luncibilika kancane emanzini. I-Flash point cishe ngo-140°F. Ingcolisa isikhumba, amehlo kanye nolwelwesi lwamafinyila. Inobuthi kancane ngokugwinya, ukumunca isikhumba kanye nokuphefumula. Isetshenziswa ekwenzeni izinamathiselo namanye amakhemikhali.

Izicelo ze-BDMA

Okuphakathi, ikakhulukazi kwamakhemikhali e-quaternary ammonium; i-catalyst esusa i-hydrohalogenating; i-inhibitor yokugqwala; i-acid neutralizer; amakhemikhali okubhaka; izinamathiselo; i-cellulose modifier.
I-N,N-Dimethylbenzylmine isetshenziswa ekulungiseleleni i-bis[(N,N-dimethylamino)benzyl] selenide. Isebenza njengesikhuthazi ekusabeleni kokwelapha kwezakhi ze-diglycidyl ether ye-bisphenol A kanye ne-tetrahydrophthalic anhydride. Idlula ku-directed ortho metalation ne-butyl lithium. Isabela ne-methyl iodide ukuze ithole usawoti we-ammonium, osetshenziswa njenge-phase transfer catalysts. Ngaphezu kwalokho, isetshenziswa njengesikhuthazi ekwakhiweni kwama-polyurethane foams kanye nama-epoxy resins.
I-N,N-Dimethylbenzylmine yasetshenziswa ekwakhiweni kwe-bis[(N,N-dimethylamino)benzyl] selenide. Isetshenziswe njenge-catalyst ngesikhathi sokusabela kokwelapha kwezakhi ze-diglycidyl ether ye-bisphenol A kanye ne-tetrahydrophthalic anhydride.

Ukulungiselela: 25% i-Aqueous Dimethylamine, amagremu angu-1088

I-Benzyl Chloride, amagremu angu-126.6

Esisetshenzisweni seSibonelo 1, i-benzyl chloride yengezwe ngokuwa phansi esikhathini samahora amabili ku-amine (isilinganiso se-molar 1 kuya ku-6) ngesivinini esanele ukugcina izinga lokushisa lingaphansi kuka-40°C. Ukuxuba kwaqhubeka ekushiseni kwegumbi ihora elengeziwe ukuqinisekisa ukuqedwa kokusabela okukhonjiswe yi-equation engezansi.

Ngemva kwalokho ingxube yokusabela yapholiswa ku-funnel ehlukanisiwe ngenkathi imi esiqandisini esigcinwe ku-5°C. yahlukaniswa yaba izendlalelo ezimbili. Ingqimba ephezulu yamafutha, enesisindo esingu-111.5g, yasuswa futhi yacwiliswa ngomusi kuze kube yilapho kungasabonakali ingxenye ye-oleaginous ku-distillate njengoba ifika. I-distillate eluhlaza yatholakala ukuthi iqukethe u-103.5g we-N,N-dimethylbenzylamine (76.1% wethiyori), u-3.3g we-dimethylamine futhi ayinawo usawoti we-quaternary. I-dimethylamine yacwiliswa ngaphansi kuka-29°C ngaphansi kwengcindezi yomoya evela ku-N,N-dimethylbenzylamine (bp 82°C/18mmHg).
