Trisodium salt of N,N,N'-ethylenediamine triacetic acid was prepared by hydrolyzing 2-oxo-1, 4-piperazine diacetic acid(3-KP) in the strong base solution. Then it was combined with lauroyl chloride, hexadecanoyl chloride and benzoyl chloride respectively. N-lauroyl-ED3A and N-hexadecanoyl-ED3A were prepared in succsess. The molecular structure of N-lauroyl-ED3A was characterized by ~1HNMR and ~(13)CNMR. The molecular structure of N-hexadecanoyl-ED3A was characterized by 1HNMR.

A novel method for determination of benzoyl peroxide with spectrophotometry was developed. Inclusion ratio of β cyclodextrin to dibenzoy peroxide and benzoic acid is obtained with spectrophotometry.The mechanism of the inclusion was studied,too. The results showed that β-CD react with dibenzoyl peroxide to form a 1:1 or 2:1 host-guest complex, with the apparent formation constants of 5.0× 10~2and 2.5× 10~4 , respectively.β-CD reacts with benzoic acid to form a 1:1 host-guest complex with the apparent formation constant of 6.9 × 10~2 after the dibenzoyl peroxide was reduced by hydroxyl ammonium chloride.
