Gabatarwa
Monochloroacetyl chloride (kuma aka sani da chloroyl chloride, acetyl chloride) wani fili ne na kwayoyin halitta. Kaddarorinsa sune kamar haka:
1. Bayyanar: ruwa mara launi ko rawaya;
2. Wari: wari na musamman;
3. Yawa: 1.40 g/mL;
Monochloroacetyl chloride ana amfani da shi sosai a cikin haɗin gwiwar kwayoyin halitta kuma yana da amfani masu zuwa:
1. A matsayin reagent acylation: ana iya amfani dashi don amsawar esterification, wanda ke amsa acid tare da barasa don samar da ester;
2. A matsayin acetylation reagent: zai iya maye gurbin aiki hydrogen zarra tare da wani acetyl kungiyar, kamar gabatarwar acetyl ayyuka kungiyoyin a aromatic mahadi;
3. A matsayin chlorinated reagent: zai iya gabatar da chlorine atom a madadin chloride ions;
4. Ana amfani da shi don shirya wasu mahadi na halitta, kamar ketones, aldehydes, acids, da dai sauransu.
Monochloroacetyl chloride yawanci ana shirya shi ta hanyoyi masu zuwa:
1. An shirya shi ta hanyar amsawar acetyl chloride da trichloride, kuma samfuran halayen sune monochloroacetyl chloride da trichloroacetic acid:
C2H4O + Cl2O3 → CCl3COCl + CloOCOOH;
2. Kai tsaye amsa acetic acid tare da chlorine don samar da monochloroacetyl chloride:
C2H4O + Cl2 → CCl3COCl + HCl.
Lokacin amfani da monochloroacetyl chloride, ya kamata a lura da bayanan aminci masu zuwa:
1. Yana da ƙamshi mai ƙamshi da tururi, kuma yakamata a yi masa aiki a wuri mai kyau;
2. Ko da yake ba mai ƙonewa ba ne, amma idan ta ci karo da wata majiyar wuta, za ta mayar da martani mai tsanani, tana fitar da iskar gas mai guba, kuma a nisantar da ita daga buɗe wuta;
3. Lokacin amfani da adanawa, ya zama dole don kauce wa hulɗa tare da oxidants mai ƙarfi, alkalis, foda na ƙarfe da sauran abubuwa don hana halayen haɗari;
4. Yana da haushi ga fata, idanu da tsarin numfashi, kuma ya kamata a yi amfani da su da safar hannu, tabarau da abin rufe fuska;
5. Idan an sha shaka ko tuntuɓar juna, a wanke wurin da abin ya shafa nan da nan kuma a nemi taimakon likita idan akwai alamun cutar.
