Membrane permeation of water—alcohol binary mixtures

Intracellular ethanol — accumulation and exit from yeast and other cells

“…This value is only 200times lower than the diffusivity of sucrose in water. For comparison, the diffusivity of ethanol in cellophane or cellulose acetate is 2 x 10 -8 cm2/s and 1 x 10-8 cmZ/s respectively [23]. Mechanisms other than a simple diffusional barrier are therefore required to explain any accumulation of intracellular ethanol.…”

Gas permeability of a novel cellulose membrane

“…For researches of dialysis [10], liquid permeation [11,12] [13][14][15]23,26] and pervaporation [16], the liquid content in the membranes is an important parameter concerning permeability. The state of water in cellulosic membranes has been a subject of interest for many years [17][18][19].…”

Cellulose-poly(acrylamide or acrylic acid) interpenetrating polymer network membranes for the pervaporation of water-ethanol mixtures

“…8,9 The water separation. [4][5][6] Cellulose membranes exhibit separation factor of membranes based on CMC ingood mechanical characteristics but their selectivity creased from 500 to 2000 when 20% PAA was added with respect to water in pervaporation processes is to casting solutions for increasing the ionic group relatively low. Thus, the separation factor for cellocontent.…”
