Selelekela
Monochloroacetyl chloride (eo hape e tsejoang e le chloroyl chloride, acetyl chloride) ke motsoako oa lintho tse phelang. Lintho tsa eona ke tse latelang:
1. Ponahalo: mokelikeli o se nang 'mala kapa o mosehla;
2. Monko: monko o khethehileng o hlabang;
3. Boima ba 'mele: 1.40 g / mL;
Monochloroacetyl chloride hangata e sebelisoa ho organic synthesis mme e na le litšebeliso tse latelang:
1. E le reagent ea acylation: e ka sebelisoa bakeng sa esterification reaction, e sebetsanang le asiti le joala ho etsa ester;
2. Joaloka reagent ea acetylation: e ka nka sebaka sa athomo ea hydrogen e sebetsang ka sehlopha sa acetyl, joalo ka ho kenyelletsa lihlopha tse sebetsang tsa acetyl ka metsoako e nkhang hamonate;
3. Joaloka reagent ea chlorine: e ka hlahisa liathomo tsa chlorine molemong oa li-ion tsa chloride;
4. E sebelisetsoa ho lokisetsa metsoako e meng ea lintho tse phelang, tse kang ketone, aldehydes, acids, joalo-joalo.
Monochloroacetyl chloride hangata e lokisoa ka litsela tse latelang:
1. E lokiselitsoe ke karabelo ea acetyl chloride le trichloride, 'me lihlahisoa tsa karabelo ke monochloroacetyl chloride le trichloroacetic acid:
C2H4O + Cl2O3 → CCl3COCl + ClOCOOH;
2. Karabelo e tobileng ea asiti ea acetic ka chlorine ho hlahisa monochloroacetyl chloride:
C2H4O + Cl2 → CCl3COCl + HCl.
Ha u sebelisa monochloroacetyl chloride, lintlha tse latelang tsa polokeho li lokela ho hlokomeloa:
1. E na le monko o monate le mouoane, 'me e lokela ho sebetsoa sebakeng se nang le moea o motle;
2. Le hoja e sa chese, e tla itšoara ka mabifi ha e kopana le mohloli o tukang, e hlahisang likhase tse chefo, 'me e lokela ho bolokoa hole le malakabe a bulehileng;
3. Ha u sebelisa le ho boloka, hoa hlokahala ho qoba ho kopana le li-oxidants tse matla, alkalis, phofo ea tšepe le lintho tse ling ho thibela liketso tse kotsi;
4. E halefisa letlalo, mahlo le tsamaiso ea ho hema, 'me e lokela ho sebelisoa ka li-gloves, likhalase le mask a sireletsang;
5. Haeba ho ka etsahala hore motho a hema ka phoso kapa a kopane, hlatsoa sebaka se amehileng hang-hang 'me u batle thuso ea bongaka haeba ho na le matšoao.
