DEFINITION
Classification: 208/348
(under subclass 347) Processes wherein a nongaseous compound is added to the distilland prior to or during the distillation.
(1) Note. The additive materials may aid the distillation,
per se, or prevent corrosion of the apparatus, or may be volatilized during the distillation.
