Gabatarwa
acid ethyl ester wani fili ne na kwayoyin halitta tare da dabarar sinadarai C8H8BrNO2. Ruwa ne mara launi mai kamshi na musamman. Filin yana narkewa a cikin abubuwan kaushi na halitta kamar ethanol, dimethylformamide da benzene, kuma maras narkewa cikin ruwa.
acid ethyl ester yana da fa'idar aikace-aikace masu yawa a cikin haɗin gwiwar kwayoyin halitta. Ana iya amfani da shi azaman tsaka-tsakin magunguna don haɗa nau'ikan magunguna da ƙwayoyin ƙwayoyin cuta. Bugu da ƙari, ana iya amfani da shi a cikin halayen Gormperman da halayen giciye na palladium-catalyzed a cikin haɗin gwiwar kwayoyin halitta.
Akwai hanyoyi guda biyu na gama gari don acid ethyl ester:
1. Ana samun shi ta hanyar amsawar 6-bromopyridine da chloroacetate, sa'an nan kuma an yi amfani da shi tare da alkali bayan amsawa.
2. Ta hanyar 6-bromopyridine da chloroacetic acid ester reaction, acid chloride, sa'an nan kuma amsa tare da barasa don samun samfurin.
Ana buƙatar matakan tsaro lokacin amfani da adanar acid ethyl ester. Ruwa ne mai ƙonewa kuma yakamata a adana shi a wuri mai sanyi, da iska mai kyau, nesa da wuta da yanayin zafi. Ya kamata a sanya kayan kariya da suka dace, kamar safofin hannu na lab da tabarau, yayin aiki. Idan ciki ko tuntuɓar fata ko idanu, kurkura nan da nan da ruwa mai yawa kuma ku nemi taimakon likita.
