Process and apparatus for separating and purifying condensations products

Claim 1

A METHOD OF REMOVING WATER SOLUBLE IMPURITIES FORM RAW MONOMERIC MATERIALS FOR THE PREPARATION OF SYNTHETIC LINEAR HIGH MOLECULAR POLYAMIDES, COMPRISING THE STEPS OF INTRODUCING A MIXTURE OF SAID RAW MONOMRIC MATERIALS AND WATER, IN A VERTICALLY ELONGATED REACTION SPACE, WEIGHT OF WATER, IN A VERTICALLY ELONGATED REACTION SPACE, HEATING SAID SPACE TO TEMPERATURES ABOVE 180*C. CONCURRENTLY MAINTAINING IN SAID SPACE A PRESSURE SUFFICIENT TO PREVENT THE WATER FROM BOILING CONTINUING SAID HEATING WHILE MAINTAINING THE LOWERMOST ZONE OF SAID SPACE AT A TEMPERATURE LOWER THAN THOSE OBTAINING IN THE BALANCE OF SAID SPACE AND WHILE MAINTAINING THE WATER IN THE LIQUID STATE, UNTIL A LOW MOLECULAR WEIGHT POLYAMIDE HAS FORMED, SAID POLYAMIDE AND SAID WATER CONTAINING THE WATER SOLUBLE IMPURITIES FORMING TWO DISTINCT LAYERS, THE POLYAMIDE LAYER BEING OF GREATER DENSITY, POSITIONED IN SAID LOWERMOST ZONE OF SAID SPACE, AND SUBTANTIALLY FREE FROM WATER SOLUBLE IMPURITIES, THE WATER LAYER BEING SUPERIMPOSED THEREON, AND THEREAFTER SEPARATING SAID WATER CONTAINING SAID WATER SOLUBLE IMPURITIES FROM SAID LOW MOLECULAR WEIGHT POLYAMIDE AND DISCHARGING THE LATTER FROM SAID REACTION SPACE.
