Igiciro cyiza cy'umukora Dimethylbenzylamine (BDMA) CAS:103-83-3

ibisobanuro bigufi:

Dimethylbenzylamine (BDMA) ni amazi adafite ibara cyangwa umuhondo woroshye afite impumuro nziza. Afite ubucucike buke ugereranyije n'amazi kandi ashongesha gato mu mazi. Afite ubushyuhe bugera kuri 140°F. Yangiza uruhu, amaso n'imitsi. Agira uburozi buke iyo umuntu ayinyoye, ayikuramo cyangwa ayihumeka. Akoreshwa mu gukora kole n'ibindi binyabutabire.

Imikoreshereze ya BDMA

Intermediate, cyane cyane ku bintu bya ammonium bya quaternary; catalyst ikuraho amazi; ibuza corrosion; aside neutralizer; ibintu byo gusya; kole; modifier ya cellulose.
N,N-Dimethylbenzylamine ikoreshwa mu gutegura selenide ya bis[(N,N-dimethylamino)benzyl]. Ikora nk'ingufu mu gusubiza neza imiterere ya diglycidyl ether ya bisphenol A na tetrahydrophthalic anhydride. Inyura mu byuma bya ortho metalation hamwe na butyl lithium. Ikorana na methyl iyode kugira ngo ibone umunyu wa ammonium, ukoreshwa nk'ingufu zo kohereza ibintu. Byongeye kandi, ikoreshwa nk'ingufu zo gukora ifuro rya polyurethane na epoxy resins.
N,N-Dimethylbenzylmine yakoreshejwe mu gukora bis[(N,N-dimethylamino)benzyl] selenide. Yakoreshejwe nk'umusemburo mu gihe cyo kuvura ingaruka z'imiti ya diglycidyl ether ya bisphenol A na tetrahydrophthalic anhydride.

Uburyo bwo gutegura: 25% Dimethylamine y'amazi, garama 1088

Benzyl Chloride, garama 126.6

Mu gikoresho cyo mu rugero rwa 1, benzyl chloride yongewemo mu gihe cy'amasaha abiri kuri amine (ikigereranyo cya molar 1 kugeza kuri 6) ku gipimo gihagije kugira ngo ubushyuhe bugume munsi ya 40°C. Gukangura byakomeje ku bushyuhe bw'icyumba mu gihe cy'isaha y'inyongera kugira ngo harebwe ko igisubizo cyagaragajwe n'ikigereranyo kiri hepfo kirarangiye.

Nyuma y’aho, uruvange rw’ibisubizo rwakonjeshejwe mu gice cyo gutandukanya ibintu, ruhagaze muri firigo igumanye ubushyuhe bwa 5°C. rucibwamo ibice bibiri. Igice cyo hejuru cy’amavuta, gipima garama 111.5, cyakuweho maze gitembanywa n’umwuka kugeza igihe nta kindi gice cy’amavuta cyagaragaye muri distillate ubwo cyazaga. Distillate isanzwe yagaragaye ko irimo garama 103.5 za N,N-dimethylbenzylamine (76.1% by’inyigisho), garama 3.3 za dimethylamine kandi nta myunyu ngugu ya quaternary. Dimethylamine yatembanywe munsi ya garama 29 za C kubera igitutu cy’ikirere cya N,N-dimethylbenzylamine (bp 82°C/18mmHg).
