ABSTRACT:
A method is provided for the preparation of high-purity 1,3-butylene glycol from acetaldehyde. In the method, acetaldehyde is condensed in the presence of base to form a mixture of acetaldols, and the acetaldols are then converted to 1,3-butylene glycol by hydrogenation. Chemical treatment and distillation processes are described which provide 1,3-butylene glycol of very high purity.
