Abstract
This invention relates to a process for separating an aldehyde that contains at least seven carbon atoms and that is free of alpha substituents from a solution containing the aldehyde and a non-polar organic liquid which process comprises contacting the solution with water under conditions such that a solid hydrate of the aldehyde forms and separating the solid hydrate from the solution. This invention also relates to novel hydrates so produced.
Claims10
A process for separating an aldehyde that contains at least seven carbon atoms and that is free of alpha substituents from a solution containing the aldehyde and a non-polar organic liquid which process comprises contacting the solution with water to form a solid hydrate of the aldehyde by the reaction of the aldehyde with the water at a temperature above the melting point of the aldehyde but below the decomposition temperature of the solid hydrate and separating the solid hydrate from the solution.
A solid hydrate having the formula:
- ##STR4## wherein R is a monovalent hydrocarbon group containing from 5 to 25 carbon atoms inclusive.
The solid hydrate of normal heptanal.
The solid hydrate of normal nonanal.
The solid hydrate of normal undecanal.
The solid hydrate of normal tridecanal.
The solid hydrate of normal pentadecanal.
The solid hydrate of normal hydrocinnamic aldehyde.
