Ftal angidridi va uning imidli hosilalari kimyo sanoati va farmatsevtika
sohalarida katta ahamiyatga ega [1-4]. Jumladan, gidroksialkilftalimidlar asosida
sintez qilinadigan moddalar qishloq xo'jaligida insektitsid, siklooksigenaza turidagi
fermentlarning ingibitorlari, alkillovchi agentlar sifatida foydalaniladi[5-7].
Ushbu ish mono xlor-, brom-, yod sirka kislotalarining N--gidroksietilftalimid
va metilolftalimidlar bilan murakkabefirlari sinteziga qaratilgan.
Monogalogen sirka kislotalari bilan N--gidroksietilftalimid va metilolftalimid
orasida eterifikatsiya reaksialari benzol erituvchiligida va sulfat kislota
katalizatorligida, 4-6 soat davomida olib borildi:
