Isothermal chemical dissipative structures

There are two fundamental requisites for the experimental study of isothermal chemical dissipative structures (i) The reaction must be maintained in constant 

These are sensitive to changes in concentration, nature of reactions and temperature etc. 

Hopf bifurcation and Jug Handle (JH) type bifurcation are most commonly observed in chemical systems. In the former case, at the bifurcation point, time period remains finite but amplitude tends to zero. However, in the latter case both the time period and amplitude have finite values. 

Bifurcation features and deformation of limit cycles for NaH2P04 -h cycle hexanone/acetone -I- Mn + -i- BrOj -i- H2SO4 oscillatory reaction system have been reported [12]. When acetone is used as the organic substrate, the reaction system yields unperturbed limit cycles. However, in the case of cyclohexanone system, the limit cycles are deformed and knot is obtained. At the upper limit, Hopf bifurcation is obtained in the case of acetone while JH type bifurcation is obtained in the case of cyclohexanone.
