Abstract

A simple and rapid method of quantitative analysis mixtures which includes benzaldehyde,cinnamaldehyde and 5-phenyl-2,4-pentadienal was established with the use of equal-absorption point,the relationships between concentration and absorbance was established by equal-absorption point:CPPDA=(A338+0.038 9)/0.174 0,C肉桂醛=(A303-0.117 7 CPPDA)/0.113 8,C苯甲醛=(A255-0.042 7 C肉桂醛-0.020 9 CPPDA)/0.059 7.The hydrolysis reactions of cinnamaldehyde were studied in the condition of 40～60 ℃ and low concentration.The results show that the degree of hydrolysis reaction depends on temperature and time.The activation energy evaluated from the Arrhenius equation is 56.59 kJ/mol.
