✦ Synopsis


The transition temperature (340 K) and enthalpy change (3.7 + 0.5 kJ mo1-1) of the monoclinic-orthorhombic phase transition in highly siliceous zeolite ZSM-5 (Si/AI = 639) were measured by differential scanning calorimetry (d.s.c.). The transition temperature determined is in agreement with that due to 29Si m.a.s.n.m.r..
