Figure 1 The effect of crystallization temperature on content
of palmitoleic acid (a) and the effect of crystallization temperature on
yield of the palmitoleic acid at the first crystallization stage (b).
Crystallization conditions: 5 g SPOMF, 60 mL solvent [SPOMF: solvent
ratio 1:12 (w/v)], methanol and acetone as the solvents,
crystallization time of 12 h.
Figure 2 Optimization of crystallization conditions at the
first crystallization stage. Crystallization conditions (a): 5 g SPOMF,
60 mL solvent [SPOMF: solvent ratio 1:12 (w/v)], crystallization
temperature of -20 °C, crystallization time of 12 h; (b): 5 g SPOMF,
SPOMF to methanol ratio of 1:9 to 1:18 (w/v), crystallization
temperature of -20 °C, crystallization time of 12 h; (c): 5 g SPOMF, 75
mL methanol [SPOMF to methanol ratio 1:15 (w/v)], crystallization
temperature of -20 °C, crystallization time of 4 h to 12 h.
