- Abstract
The method of experimental statistical analysis was applied to study the effect of mass ratio of phenol and lignin (factor X1) and the weight ratio of thereof mixture with formaldehyde (factor X2) on the values of specific parameters of the porous structure obtained organic lignin – phenolformaldehyde aerogels. Based on the evaluation of the mathematical model was established that under the observance terms of X1 = 0,65-0,78 and X2 = 1,7 the maximum predicted values of the specific surface area and mesopore volume of obtained organic aerogels are 485 m2 /g and 1,83 cm3/g, accordingly. Under optimal values of X1 = 0.25, and X2 = 1.25 calculated values reach a macropore volume of 4.05 cm3 /g and total pore volume – 4.67 cm 3 /g
