METHOD OF PURIFICATION OF PENTAFLUOROETHANE

摘要

FIELD: various engineering fields. SUBSTANCE: invention describes purification of pentafluoroethane (coolant-125) used as ozoneproof coolant carrier and propellant from pentafluorochloroethane (coolant-125) impurity. The method comprises contacting gaseous pentafluoroethane with absorber. The latter includes water containing from 1 to 100 mg/l of chlorine salt. EFFECT: lower power consumption during purification process. 5 ex, 1 tblo
