Mawu Oyamba
Monochloroacetyl chloride (yomwe imadziwikanso kuti chloroyl chloride, acetyl chloride) ndi gulu lachilengedwe. Makhalidwe ake ndi awa:
1. Maonekedwe: madzi opanda mtundu kapena achikasu;
2. Kununkhira: fungo lapadera lamphamvu;
3. Kachulukidwe: 1.40 g / mL;
Monochloroacetyl chloride amagwiritsidwa ntchito kwambiri popanga organic synthesis ndipo ali ndi izi:
1. Monga reagent acylation: angagwiritsidwe ntchito esterification anachita, amene amachitira asidi ndi mowa kupanga ester;
2. Monga reagent ya acetylation: imatha kusintha atomu ya haidrojeni yogwira ntchito ndi gulu la acetyl, monga kuyambitsa magulu a acetyl mumagulu onunkhira;
3. Monga chlorine reagent: imatha kuyambitsa maatomu a klorini m'malo mwa ayoni a kloridi;
4. Amagwiritsidwa ntchito pokonzekera mankhwala ena achilengedwe, monga ketoni, aldehydes, acids, etc.
Monochloroacetyl chloride nthawi zambiri imakonzedwa motere:
1. Zimakonzedwa ndi zomwe acetyl chloride ndi trichloride, ndipo zotsatira zake ndi monochloroacetyl chloride ndi trichloroacetic acid:
C2H4O + Cl2O3 → CCl3COCl + ClOCOOH;
2. Direct anachita acetic asidi ndi klorini kupanga monochloroacetyl kolorayidi:
C2H4O + Cl2 → CCl3COCl + HCl.
Mukamagwiritsa ntchito monochloroacetyl chloride, mfundo zotsatirazi ziyenera kudziwidwa:
1. Imakhala ndi fungo loipa ndi nthunzi, ndipo iyenera kugwiritsidwa ntchito pamalo abwino mpweya wabwino;
2. Ngakhale kuti sichikhoza kuyaka, idzachita mwachiwawa ikakumana ndi gwero loyatsira, kutulutsa mpweya wapoizoni, ndipo iyenera kusungidwa kutali ndi moto wosayatsa;
3. Mukamagwiritsa ntchito ndikusunga, ndikofunikira kupewa kukhudzana ndi okosijeni amphamvu, alkali, ufa wachitsulo ndi zinthu zina kuti mupewe zoopsa;
4. Zimakwiyitsa khungu, maso ndi kupuma, ndipo ziyenera kugwiritsidwa ntchito ndi magolovesi, magalasi ndi masks otetezera;
5. Mukapuma mwangozi kapena kukhudza, sambani malo omwe akhudzidwa mwamsanga ndikupempha thandizo lachipatala ngati pali zizindikiro.
