In this paper we consider a model of quintessential inflation based upon inverse hyperbolic potential. We employ curvaton mechanism for reheating which is more efficient than gravitational
particle production; the mechanism complies with nucleosynthesis constraint due to relic gravity
waves. We obtain a lower bound on the coupling constant
g that governs the interaction of curvaton
with matter fields. We study curvaton decay before domination and decay after domination and
plot the allowed region in the parameter space in both cases.
