Okwu mmalite

Monochloroacetyl chloride (a makwaara dị ka chloroyl chloride, acetyl chloride) bụ ngwakọta organic. Njirimara ya bụ ndị a:

 

1. Ọdịdị: mmiri mmiri na-enweghị agba ma ọ bụ odo;

2. Isi: isi ísì pụrụ iche;

3. Njupụta: 1.40 g/mL;

 

A na-ejikarị Monochloroacetyl chloride na njikọ organic ma nwee ihe ndị a:

 

1. Dị ka acylation reagent: enwere ike iji ya mee ihe maka mmeghachi omume esterification, nke na-emeghachi acid na mmanya na-eme ka ester;

2. Dị ka acetylation reagent: ọ nwere ike dochie arụ ọrụ hydrogen atom na otu acetyl otu, dị ka iwebata nke acetyl arụ ọrụ dị iche iche na aromatic ogige;

3. Dị ka chlorinated reagent: ọ nwere ike iwebata chlorine atọm n'aha chloride ion;

4. A na-eji ya akwadebe ogige ndị ọzọ dị ndụ, dị ka ketones, aldehydes, acids, wdg.

 

A na-akwadokarị Monochloroacetyl chloride n'ụzọ ndị a:

 

1. A na-akwado ya site na mmeghachi omume nke acetyl chloride na trichloride, na ngwaahịa mmeghachi omume bụ monochloroacetyl chloride na trichloroacetic acid:

C2H4O + Cl2O3 → CCl3COCl + ClOCOOH;

2. Mmeghachi omume ozugbo nke acetic acid na chlorine iji mepụta monochloroacetyl chloride:

C2H4O + Cl2 → CCl3COCl + HCl.

 

Mgbe ị na-eji monochloroacetyl chloride, ekwesịrị ịdebe ozi nchekwa ndị a:

 

1. Ọ nwere isi na-esi ísì ụtọ na uzuoku, a ga-arụkwa ya na ebe ikuku na-ekpo ọkụ;

2. Ọ bụ ezie na ọ naghị ere ọkụ, ọ ga-emeghachi omume n'ike mgbe ọ zutere ebe mgbanye ọkụ, na-emepụta gas na-egbu egbu, na ekwesịrị ka edebe ya pụọ ​​na ọkụ;

3. Mgbe ị na-eji ma na-echekwa, ọ dị mkpa iji zere kọntaktị na oxidants siri ike, alkalis, ntụ ntụ na ihe ndị ọzọ iji gbochie mmeghachi omume dị ize ndụ;

4. Ọ na-agbakasị ahụ akpụkpọ ahụ, anya na usoro iku ume, ma ekwesịrị iji uwe aka, enyo na mkpuchi nchebe rụọ ọrụ;

5. Ọ bụrụ na ikuku ume ma ọ bụ kọntaktị na mberede, saa ebe ahụ emetụtara ozugbo ma chọọ enyemaka ahụike ma ọ bụrụ na enwere mgbaàmà ọ bụla.
