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 ekuhlanganiseni 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 kuzinga lokushisa elijwayelekile 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).
