Suga, Hiroshi published the artcileCrystallochemical study by differential thermal analysis. II. Detection of phase transition, Application In Synthesis of 594-81-0, the publication is Nippon Kagaku Zasshi (1961), 29-32, database is CAplus.
The phase transition was detected for some mol. crystals by means of a programmed automatic controlling-and-recording apparatus for differential thermal analysis. 2,3-Dimethyl-2,3-dibromobutane showed transitions at -91 and 70-80° with estimated heats of transition of about 500 and 1000 cal./mole, resp. Si(OMe)4, AcNHMe, and triglycine sulfate showed transitions at -98, 2, and 0-50° with estimated heats of transition of about 100, 100, and 200 cal./mole, resp. The phase transition of resorcinol from the α-type to the β-type was detected thermally. The estimated enthalpy accompanying this transition agreed with the value of Ubbelohde and Robertson (CA 31, 77193) calculated from the heats of solution of the 2 crystalline forms in water.
