Okwu mmalite
acid ethyl ester bụ ngwakọta organic nke nwere usoro kemịkalụ C8H8BrNO2. Ọ bụ mmiri mmiri na-enweghị agba nke nwere isi pụrụ iche. Ngwakọta ahụ bụ soluble na organic mgbaze dị ka ethanol, dimethylformamide na benzene, na-adịghị ike soluble na mmiri.
acid ethyl ester nwere ọtụtụ ngwa ngwa na njikọ organic. Enwere ike iji ya dị ka onye na-ahụ maka ọgwụ na-emepụta ọgwụ maka nchịkọta nke ọgwụ dịgasị iche iche na ụmụ irighiri ihe ndị na-emepụta ihe. Tụkwasị na nke ahụ, a pụkwara iji ya mee ihe na mmeghachi omume Gormperman na palladium-catalyzed cross-coupling reactions na organic synthesis.
Enwere ụzọ abụọ a na-ahụkarị maka acid ethyl ester:
1. A na-enweta ya site na mmeghachi omume nke 6-bromopyridine na chloroacetate, wee jiri alkali mee hydrolyzed mgbe mmeghachi omume ahụ gasịrị.
2. Site na 6-bromopyridine na chloroacetic acid ester mmeghachi omume, acid chloride, wee meghachi omume na mmanya na-aba n'anya iji nweta ngwaahịa ahụ.
Achọrọ nlezianya nchekwa mgbe ị na-eji na ịchekwa acid ethyl ester. Ọ bụ mmiri mmiri na-ere ọkụ, ekwesịrị ịchekwa ya n'ebe dị jụụ, nke ikuku na-ekpo ọkụ, na-adịghị na ọkụ na oke okpomọkụ. Ekwesịrị iyi akụrụngwa nchebe kwesịrị ekwesị, dị ka uwe ụlọ nyocha na goggles, mgbe a na-arụ ọrụ. Ọ bụrụ na ntinye ma ọ bụ kọntaktị na akpụkpọ ahụ ma ọ bụ anya, jiri mmiri buru ibu sachaa ozugbo wee chọọ enyemaka ahụike.
