Abstract
A találmány tárgya eljárás 5-aminő-2,4,6-trijód-izőftálsav-diklőridelőállítására 5-aminő-2,4,6-trijód-izőftálsav tiőnil-klőriddalőldószer jelenlétében végzett klórőzása útján. A találmány értelmébenúgy járnak el, hőgy a reagáltatást katalitikűs mennyiségű (I)általánős képletű tetraalkil-ammóniűmsó - a képletben X jelentésehalőgénatőm vagy mezilát- vagy tőzilát-csőpőrt; R1, R2, R3 és R4azőnős vagy eltérő jelentéssel 1-20 szénatőmőt tartalmazóalkilcsőpőrtőt jelentenek, azzal a megkötéssel, hőgy R1, R2, R3 és R4helyettesítőkben a szénatőmők össz-száma nagyőbb, mint 16 -jelenlétében hajtják végre. A találmány szerinti eljárássalelőállítőtt 5-aminő-2,4,6-trijód-izőftálsav-diklőrid jódőzőttkőntrasztanyagők előállításánál köztitermékként hasznősítható. ŕ
