The enthalpy of reaction of the 2-chloroethylideneaminocarbamic acid ethyle
ster formation from chloroacetaldehyde and hydrazinoformic acid ethylester
in ethanol at the temperature of 298.15 K has been determined by a microcal
orimeter. Experimental results gave the enthalpy of formation Delta H-r(m)t
heta = (-16.07 +/- 0.079) kJ mol(-1), the reaction order of this reaction n
= 1; the rate constant k = 1.190 x 10(-3) s(-1) and the free energy of act
ivation DeltaG(not equal)(theta) = 89.718 kJ mol(-1). The result indicates
that the reaction takes place easily at room temperature. (C) 2001 Elsevier
