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

incazelo emfushane:

I-Dimethylbenzylamine (BDMA) iwuketshezi olungenambala ukuya kokuphuzi olukhanyayo olunephunga elimnandi. Iminyene kancane kunamanzi futhi incibilika kancane emanzini. Iphoyinti elikhanyayo licishe libe ngu-140°F. Igqwala esikhunjeni, emehlweni kanye nolwelwesi lwamafinyila. Inobuthi obuncane ngokumunca, ukumunca isikhumba kanye nokuhogela. Isetshenziswa ekwenzeni izinto zokunamathisela namanye amakhemikhali.

Izicelo ze-BDMA

Okuphakathi, ikakhulukazi ama-quaternary ammonium compounds; i-dehydrohalogenating catalyst; i-corrosion inhibitor; i-acid neutralizer; ama-potting compounds; izinto zokunamathisela; i-cellulose modifier.
I-N,N-Dimethylbenzylamine isetshenziswa ekulungiseleleni i-bis[(N,N-dimethylamino)benzyl] selenide. Isebenza njenge-catalyst ekwelapheni ukusabela kokwakhiwa kwe-diglycidyl ether ye-bisphenol A kanye ne-tetrahydrophthalic anhydride. Idlula i-ortho metalation eqondisiwe nge-butyl lithium. Ihlangana ne-methyl iodide ukuze ithole usawoti we-ammonium, osetshenziswa njengezisusa zokudlulisa isigaba. Ngaphezu kwalokho, isetshenziswa njenge-catalyst yokwakhiwa kwamagwebu e-polyurethane nama-epoxy resins.
I-N, N-Dimethylbenzylamine isetshenziswe ekuhlanganisweni kwe-bis [(N,N-dimethylamino) benzyl] selenide. Isetshenziswe njenge-catalyst ngesikhathi sokwelapha ukusabela kokwakhiwa kwe-diglycidyl ether ye-bisphenol A ne-tetrahydrophthalic anhydride.

Ukulungiselela: 25% Dimethylamine enamanzi, 1088 amagremu

I-Benzyl Chloride, i-126.6 amagremu

Kumshini weSibonelo soku-1, i-benzyl chloride yengezwa ngokudonsela phansi esikhathini esingamahora amabili ku-amine (isilinganiso se-molar 1 kuya ku-6) ngesilinganiso esanele ukugcina izinga lokushisa lingaphansi kuka-40°C. Ukugqugquzela kuye kwaqhutshekwa kuthempelesha yegumbi ihora elengeziwe ukuze kuqinisekiswe ukuqedwa kokusabela okushiwo isibalo esingezansi.

Ngemva kwalokho ingxube yokusabela yapholiswa kufaneli ehlukanisayo ngenkathi imi esiqandisini esigcinwe ku-5° C. futhi ihlukaniswa izingqimba ezimbili. Ungqimba lwamafutha olungaphezulu, olunesisindo esingu-111.5g, lwasuswa futhi umusi washiswa kuze kube yilapho kungasekho ngxenye ye-oleaginous eyabonwa ku-distillate njengoba ifika. I-distillate engahluziwe itholwe iqukethe u-103.5g we-N,N-dimethylbenzylamine (76.1% wethiyori), u-3.3g we-dimethylamine futhi awekho usawoti we-quaternary. I-dimethylamine yahlungwa ngaphansi kuka-29 ° C ngaphansi kwengcindezi yasemkhathini evela ku-N, N-dimethylbenzylamine (bp 82°C/18mmHg).
