Nta ntawm N, N-Diethylcarbamazine CAS 90-89-1
N, N-Diethylcarbamazine CAS 90-89-1 yog cov organic compound nrog cov khoom hauv qab no:
Cov tsos mob: tsis muaj xim rau lub teeb daj oily kua.
Ceev: 0.928 g/mL.

Kev siv Dimethylcarbamoyl
Dimethylcarbamoyl chloride tau siv los ua cov tshuaj nruab nrab hauv kev tsim cov dyes, tshuaj, tshuaj tua kab, thiab foob pob hluav taws roj (IARC 1999, HSDB 2009).
Cov kev muaj peev xwm ntawm tib neeg raug rau dimethylcarbamoyl chloride yog nqus tau, noj, thiab kev sib cuag dermal. Dimethylcarbamoyl chloride tau raug tso tawm rau ib puag ncig los ntawm kev tsim khoom thiab siv los ua ib qho nruab nrab hauv kev tsim cov tshuaj tua kab thiab tshuaj (HSDB 2009). Raws li EPA's Toxics Release Inventory, ib puag ncig kev tso tawm ntawm dimethylcarbamoyl chloride tseem nyob nruab nrab ntawm 98 thiab 366 lb txij li xyoo 1997, nrog rau feem ntau tso tawm rau saum huab cua thiab qhov seem mus rau qhov chaw tsis muaj kev phom sij pov tseg. Xyoo 2007, ib lub chaw tso tawm 260 lb ntawm dimethylcarbamoyl chloride; feem ntau (255 lb) raug tso tawm mus rau qhov chaw pov tseg pov tseg, thiab cov seem rau saum huab cua (TRI 2009). Dimethylcarbamoyl chloride tsis xav kom nyob twj ywm hauv ib puag ncig, vim tias nws hydrolyzes sai hauv dej. thiab moist av (HSDB 2009). Qhov tseem ceeb muaj peev xwm tib neeg raug rau dimethylcarbamoyl chloride yog txwv rau cov neeg ua haujlwm tshuaj, tshuaj tua kab, tshuaj pleev xim, thiab cov neeg ua haujlwm tshuaj.
Dimethylcarbamoyl chloride zoo nkaus li cov kua ntshiab ntawm chav tsev kub nrog cov ntxhiab tsw ntxhiab thiab tsim kua muag-ntev, uas decomposes sai hauv dej.
Dimethylcarbamoyl chloride zoo ib yam nrog cov kua qaub chloride uas nws cov tshuaj chlorine tuaj yeem hloov pauv rau lwm cov nucleophiles. Yog li, nws muaj peev xwm ua rau muaj kev cuam tshuam nrog cawv, phenols thiab oximes rau cov khoom sib xws N, N-dimethylcarbamates, nrog thiols rau thiolourethanes, nrog amines thiab hydroxylamine rau hloov ureas, thiab nrog imidazoles thiab triazoles rau carbamoylazoles.
Kev npaj cov txheej txheem ntawm Dimethylcarbamoyl chloride
Dimethylcarbamoyl chloride tuaj yeem tsim los ntawm ntau txoj hauv kev:
Cov tshuaj tiv thaiv nrog Phosgene thiab Dimethylamine
Txoj kev no suav nrog reacting phosgene nrog gaseous dimethylamine nyob rau hauv ib tug txaus reactor ntawm 275 degree, yielding siab ntau lawm tus nqi (90%).
Laboratory Scale Synthesis
Ntawm chav kuaj ntsuas, diphosgene lossis triphosgene tuaj yeem cuam tshuam nrog cov tshuaj aqueous dimethylamine hauv ob-theem txheej txheem ntawm benzene-xylene thiab dej, nrog sodium hydroxide ua cov kua qaub.
Txoj kev Chlorodimethylamine
Txoj kev tsis ntev los no no suav nrog kev hloov chlorodimethylamine rau qhov sib xyaw ntawm palladium catalyst nyob rau hauv siab nrog carbon monoxide nyob rau hauv chav tsev kub.
Biosynce muaj ib qho kev ywj pheej R & D thiab chaw soj ntsuam nruj me ntsis kuaj cov khoom zoo thiab muab cov neeg siv khoom zoo, peb cov khoom tau xa tawm mus rau North America, Europe, Asia thiab Africa. Peb lub hom phiaj los tsim kom muaj kev sib raug zoo nrog cov neeg siv khoom mus sij hawm ntev thiab muaj txiaj ntsig zoo thiab muab cov khoom zoo thiab cov kev pabcuam zoo.
