Influence of a third component on (liquid + liquid) phase equilibria in (butan-2-ol + water) and in (butan-1-ol + water) at pressures up to 160 MPa

摘要: Abstract (Liquid + liquid) phase equilibria of (butan-2-ol water) and (butan-1-ol have been investigated in the temperature range from 255 K to 400 at pressures up 160 MPa an optical high-pressure cell according synthetic method. The mutual miscibilities either influenced by substituting fractions alkanol another isomeric butanol or adding salts binary mixtures. For a homogeneous region temperatures below 268 was found. p ( T ) isopleths obtained are presented discussed; they demonstrate continuous transitions between several different types immiscibility phenomena liquid mixtures under high pressures.
