Isingeniso

I-Monochloroacetyl chloride (eyaziwa nangokuthi i-chloroyl chloride, i-acetyl chloride) iyinhlanganisela yezinto eziphilayo. Izici zayo zimi kanje:

 

1. Ukubukeka: uketshezi olungenambala noma oluphuzi;

2. Iphunga: iphunga elimnandi elikhethekile;

3. Ukuminyana: 1.40 g/mL;

 

I-Monochloroacetyl chloride ivame ukusetshenziswa ku-organic synthesis futhi inokusetshenziswa okulandelayo:

 

1. Njenge-acylation reagent: ingasetshenziselwa ukusabela kwe-esterification, ephendula i-asidi notshwala ukuze yakhe i-ester;

2. Njenge-reagent ye-acetylation: ingakwazi esikhundleni se-athomu ye-hydrogen esebenzayo neqembu le-acetyl, njengokwethulwa kwamaqembu asebenzayo e-acetyl kuma-compounds anephunga elimnandi;

3. Njenge-reagent ene-chlorine: ingethula ama-athomu e-chlorine egameni lama-ion e-chloride;

4. Isetshenziselwa ukulungisa amanye ama-organic compounds, njengama-ketone, ama-aldehydes, ama-acids, njll.

 

I-Monochloroacetyl chloride ivame ukulungiswa ngalezi zindlela ezilandelayo:

 

1. Ilungiswa ukusabela kwe-acetyl chloride ne-trichloride, futhi imikhiqizo yokusabela i-monochloroacetyl chloride ne-trichloroacetic acid:

C2H4O + Cl2O3 → CCl3COCl + ClOCOOH;

2. Ukusabela okuqondile kwe-acetic acid nge-chlorine ukukhiqiza i-monochloroacetyl chloride:

C2H4O + Cl2 → CCl3COCl + HCl.

 

Lapho usebenzisa i-monochloroacetyl chloride, imininingwane elandelayo yokuphepha kufanele iqashelwe:

 

1. Inephunga elimnandi nesitimu, futhi kufanele ihlinzekwe endaweni engenawo umoya;

2. Nakuba ingashi, izosabela ngobudlova lapho ihlangana nomthombo wokuthungela, ikhiqize amagesi anobuthi, futhi kufanele igcinwe kude namalangabi avulekile;

3. Uma usebenzisa futhi ugcina, kuyadingeka ukugwema ukuthintana nama-oxidants aqinile, ama-alkali, i-iron powder nezinye izinto ukuvimbela ukusabela okuyingozi;

4. Iyacasula isikhumba, amehlo kanye nesistimu yokuphefumula, futhi kufanele isetshenziswe ngamagilavu, izibuko kanye namamaski okuzivikela;

5. Uma uhogela umoya ngephutha noma uthintwa, geza indawo ethintekile ngokushesha futhi ufune usizo lwezokwelapha uma kukhona izimpawu.
