摘要： The invention relates to a method for separating pentenenitrile isomers having a relative volatility alpha in the region 1.0 - 1.3 in a pressure range of 1 - 500 kPa by means of separation. According to said method, the distillation is carried out in the presence of a liquid diluent which forms azeotropes with the pentenenitrile isomers in the same pressure conditions, whose relative volatility alpha is higher than the pentenenitrile isomers which are to be separated.

摘要： The invention relates to a method for dehydrating hydrocyanic acid by distillation. Said method is characterised in that a crude hydrocyanic acid containing between 50 and 99.9 wt. % HCN, between 0.1 and 40 wt. % water, between 0 and 15 wt. % carbon oxides and optionally between 0.01 and 1 wt. % non-volatile stabiliser is distilled in a distillation column at a pressure of between 1 bar and 2.5 bar, a sump temperature of between 100 °C and 130 °C and a head temperature of between 25 °C and 54 °C in the absence of a volatile stabiliser. A discharge stream, containing purified anhydrous hydrocyanic acid and carbon oxides is thus obtained from the head and a discharge stream containing water and optionally the non-volatile stabiliser is obtained from the sump.
