Abstract

Ozonolysis of acetic acid 1-vinyl-hexyl ester was carried out in a falling film microreactor in a continuous fashion. The influence of reaction variables (e.g., olefin concentration, ozone initial partial pressure, gas velocity, temperature and liquid flow rate) on the product formation in the liquid phase was studied over a wide range of operating conditions. Based on the obtained results, a formal reaction scheme for the ozonolysis of acetic acid 1-vinyl-hexyl ester is suggested. The acetic acid 1-formyl-hexyl ester and the corresponding carbonyl oxide are the main products of the cleavage of the primary formed ozonide. The secondary ozonide acetic acid 1-[1,2,4]trioxolan-3-yl-hexyl ester is formed by consecutive reaction of the acetic acid 1-formyl-hexyl ester and the carbonyl oxide.
