Özet
Oligomeric toluene material which has epoxy group (ETO) was prepared through reaction of toluene and epichlorohidrine in the presence of BF3. Epoxy toluene oligomere containing chloromethyl groups (ETOC) was synthesized from the treatment of NaOH and ETO for 6-8 hours. The macromolecular derivative of oligomer, (ETOC-I-6) was obtained from the reaction of ETOC and p-tert-butylcalix[6]arene (I-6) in the presence of CH3ONa. When the concentration of ETOC is greater than I-6, the reaction was observed as pseudo first order, benzene was used as solvent. The activation energy and rate constant of the reaction were calculated as 25.082 kj . mol(-1) and 3.155.10(-5) s(-1), respectively. The amounts of chlorine in ETOC-I-6 was determined 6.37% by Schoniger Method, and its molecular weight was determined as 2778.84 g . mol(-1) by cryoscopic method using benzene as solvent.
