Abstract
The aim of research the synthesis of 5,11,17,23-tetra(t-butyl)-25-monohydroxy-26,27,28-tribenzoyloxycalix[4]arene (TBMTCA) material were by one-step synthesized by benzoylation reaction of 5,11,17,23-tetra(t-butyl)-25,26,27,28-tetrahydroxycalix[4]arene (TBCA) and benzoyl chloride is (1: 3,7) mol and the refluxing 3 hours at room temperature and predicted mechanism reaction models. The product reaction of synthesis was carried out by means of FTIR and 1H-NMR spectroscopy. The results material of5,11,17,23-tetra(t-butyl)-25-monohydroxy-26,27,28-tribenzoyloxycalix[4]arene (TBMTCA)synthesized was light yellow crystalline having melting point 306-3090C in 90,2 % yields.
