VARYING POROSITY KINETIC MODEL FOR DIRECT AND REACTIVE SOLID-LIQUID EXTRACTION	2002	7	.pdf	application/pdf	4572	213	52	A mathematical model is presented accounting for the effects of porosity increase during extraction from vegetable materials. Mathematical model The overall process of extraction with simultaneous chemical reaction involves consideration of the following phenomena: 96 (a) chemical conversion of insoluble compound that is initially adsorbed or chemically bounded in a solid to soluble reaction product, prior to its diffusion through the pore space; (b) parallel release of all-soluble compounds initially present accompanied by additional solvent penetration and porosity increase.	cache/hjic-948.pdf	txt/hjic-948.txt
