PROCEDE PERFECTIONNE DE FABRICATION D'ANHYDRIDES SYMETRIQUES
摘要:
A symmetrical anhydride of formula (I) is produced by reacting a mixed anhydride (II) with a carboxylic acid (III), R1 being alkyl, alkenyl, aryl, alkylaryl, aralkyl; R2 being alkyl in C¿1?-C40, alkenyl in C1-C40, aryl, aryl-(alkyl in C1-C40) and (alkyl en C1-C40)-aryl.
