Rr. Nigmatullin et al., CONCENTRATION OF SOLUTIONS OF THERMOLABILE VITAMINS BY MEMBRANE DISTILLATION, Russian journal of applied chemistry, 66(6), 1993, pp. 1070-1073
The mass transfer during the concentration of C and B1 vitamins by mem
brane distillation is studied. The efficiency is investigated as a fun
ction of temperature and hydrodynamic regimes, concentration of vitami
ns, and membrane orientation in the field of gravitational forces.
