METHOD FOR CONCENTRATION OF COLOPHONY Russian patent published in 1997 - IPC

Abstract RU 2099378 C1

FIELD: organic technology. SUBSTANCE: method involves loading of turpentine together with live steam into colophony-boiling column; uninterrupted distillation of turpentine steam by counterflow moving of turpentine and live steam; output of aqueous-steam mixture and thus prepared colophony. Loading of turpentine and output of aqueous-steam turpentine mixture is carried out tangentially at angle of 25-45 deg. Mentioned above distillation is carried out in eddy stream, thickness thus obtained film layer being controlled within 2-7 mm range. EFFECT: improved quality of desired products while decreased expense of energy.
