I. Liszi et al., PRIMARY NUCLEATION OF TRANS-BUTADIENE-ACID IN COOLING CRYSTALLIZATIONSYSTEM, Hungarian journal of industrial chemistry, 23(1), 1995, pp. 75-79
Solubility and supersolubility curves of trans-butadiene-acid (TBA) in
aqueous media were determined from cooling crystallization experiment
s in the temperature range T = 25-96 degrees C. Metastable zone width
Delta T-max was measured at several cooling rates T at a certain satur
ated concentration. This procedure was repeated with several saturated
concentrations. Also the particle size distribution of the final prod
uct was measured. From the relation lg T vs lg Delta T-max nucleation
characteristics (n and k(N)) were determined. Mass precipitation rate
m(N) and nucleation rate N-N were calculated. This latter one shows go
od agreement with literature data.
