Wopanga mtengo wabwino Dimethbnzzylamine (BDMA) Cas: 103-83-3

Kufotokozera kwaifupi:

Dimethylbenzylamine (BDMA) ndi wopanda utoto kununkhira kwamadzi owala ndi fungo labwino. Pang'ono pang'ono kuposa madzi ndi kusungunuka pang'ono m'madzi. Kuloza pafupifupi 140 ° F. Kuwononga khungu, maso ndi mucous nembanemba. Poizoni pang'ono polowetsa, khungu lokonda khungu ndi inhalation. Ntchito popanga zomatira ndi mankhwala ena.

Ntchito za BDMA

Pakatikati, makamaka kwa mitundu ya aaranteyary; zothandizira zam'madzi; opiriza oletsa; acid ratiolizer; mafuta opanga; omata; cellulose osintha.
N-n-dimethylbenzzylamine amagwiritsidwa ntchito pokonza Bis [(n, n-N-Dimethylamino) Benyzyl] selenide. Imagwira ntchito ngati chothandizira pakuchirikiza mapangidwe a diathercidy ethercidy ethercidy wa bisphenol a ndi tetraphhthalhalic termydride. Iyo imaperekedwa motsogozedwa ndi OrHA Metelation ndi 18yl lithiamu. Zimakhudzana ndi methyl iodide kuti mutenge mchere amchere, womwe umagwiritsidwa ntchito ngati gawo losakanikirana. Kupitilira apo, imagwiritsidwa ntchito ngati chothandizira pakupanga ziphuphu za polyurethara ndi epoxy.
N, N-Dimethylbemine adagwiritsidwa ntchito mu kaphatikizidwe ka Bis [(n, N-N-D-Dimethlamino) Benyzyl] selenide. Zagwiritsidwa ntchito ngati chothandizira pakuchiritsa zomwe zimachitika pakupanga dialyciyl ethercidy ethercidy ethercidy ethercidy ethercidy ethercidy ethercidy wa bisphenol a ndi tetraphthalhthal andydraride.

Kukonzekera: 25% yamadzimadzi a Dimethylamine, 1088 magalamu

Benzyl chloride, 126.6 magalamu

Mu zida za Chitsanzo 1, benzyl chloride idawonjezeredwa nthawi ya maola awiri kupita ku Amine (molar ratio 1 mpaka 6) pamlingo wokwanira pansi pa 40 ° C. Oyambitsa adapitilirabe kutentha kwa ola lowonjezeranso kuti akwaniritse zomwe zanenedwa ndi equation pansipa.

Pambuyo pake osakaniza adazimitsidwa munthawi yolekanitsa pomwe ataimirira mu 3 ° C. ndikulekanitsidwa m'magawo awiri. Mafuta owala, olemera 111.5g, adachotsedwa ndikuwathiratu mpaka palibe gawo lina la oleleaginous lomwe limawonedwa mu distillate monga momwe zidawonekera. Kugawana kwamtunduwu kunapezeka kuti ali ndi 103.5g ya n, N-D-DimethylBzylamine (76.1% ya chiphunzitso), 3.3g ya Dimethylamine ndipo palibe mchere wa quanthtylamine. Dimethylamine adasokonekera pansi pa 29 ° C pansi pa NO, N-N-D-DimethylBzzylamine (BP 82 ° C / 18mhg).
