Abstract

<p><tt>In order to gain an understanding on the hazardous nature of heterogeneous reaction systemsin liquid-liquidphase toluene　and　benzene　sulfonation　by　sulfuric　acid　was　investigated　using　a　reaction　calorimeter（RC1）. It　was　fomd　that　the exothermic　behavior　of　sulfonation　was　inHuenced　by　the　stirrlng　efficiency　viz．the　interfacial　tension，while　it　did　not depend　on　the　acid　concentration． The　maximum　heat　release　rate　was　predicted　by　employing　a　mathematical　relationship　using　Webemumber，in　which the　overa11reactiom’ate　was　assumed　to　be　proportional to　the　size　of　the　contact　area　between　phases、The　validity　of　the relationship　was　checked　by　comparing with　the　RCI　experlmental　results、It　was　found　that　the　predicted　heat　rates </tt><tt>matched　reasonably　when　the　volumetric　fraction　of　the　dispersion　phase　was　larger　than　O.1.</tt></p>
