Taw qhia
Monochloroacetyl chloride (tseem hu ua chloroyl chloride, acetyl chloride) yog cov organic compound. Nws cov khoom yog raws li nram no:
1. Cov tsos mob: tsis muaj xim lossis daj daj;
2. Cov ntxhiab tsw: tshwj xeeb pungent tsw;
3. Ceev: 1.40 g / mL;
Monochloroacetyl chloride feem ntau yog siv rau hauv cov organic synthesis thiab muaj cov hauv qab no siv:
1. Raws li acylation reagent: nws tuaj yeem siv rau cov tshuaj tiv thaiv esterification, uas reacts acid nrog cawv los ua ester;
2. Raws li acetylation reagent: nws tuaj yeem hloov cov active hydrogen atom nrog ib pab pawg acetyl, xws li kev taw qhia ntawm acetyl functional pawg hauv cov tshuaj tsw qab;
3. Raws li chlorinated reagent: nws tuaj yeem ua kom paub cov tshuaj chlorine atoms sawv cev ntawm chloride ions;
4. Nws yog siv los npaj lwm cov organic tebchaw, xws li ketones, aldehydes, acids, thiab lwm yam.
Monochloroacetyl chloride feem ntau yog npaj raws li hauv qab no:
1. Nws yog npaj los ntawm cov tshuaj tiv thaiv ntawm acetyl chloride thiab trichloride, thiab cov khoom siv tshuaj tiv thaiv yog monochloroacetyl chloride thiab trichloroacetic acid:
C2H4O + Cl2O3 → CCl3COCl + ClOCOOH;
2. Cov tshuaj tiv thaiv ncaj qha ntawm acetic acid nrog chlorine los tsim monochloroacetyl chloride:
C2H4O + Cl2 → CCl3COCl + HCl.
Thaum siv monochloroacetyl chloride, cov ntaub ntawv kev nyab xeeb hauv qab no yuav tsum raug sau tseg:
1. Nws muaj cov ntxhiab tsw ntxhiab thiab chav, thiab yuav tsum tau ua haujlwm hauv qhov chaw muaj cua zoo;
2. Txawm hais tias nws tsis yog nplaim taws, nws yuav hnov mob hnyav thaum nws ntsib qhov hluav taws kub, ua rau cov pa phem, thiab yuav tsum tau ceev kom tsis txhob muaj hluav taws kub hnyiab;
3. Thaum siv thiab khaws cia, nws yog ib qho tsim nyog kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog, alkalis, hlau hmoov thiab lwm yam khoom los tiv thaiv kev txaus ntshai;
4. Nws yog khaus rau ntawm daim tawv nqaij, qhov muag thiab ua pa, thiab yuav tsum tau ua nrog cov hnab looj tes, tsom iav thiab cov qhov ncauj qhov ntswg tiv thaiv;
5. Nyob rau hauv rooj plaub ntawm kev nqus pa los yog kev sib cuag, ntxuav qhov chaw raug mob tam sim ntawd thiab nrhiav kev pab kho mob yog tias muaj cov tsos mob.
