ABSTRACT:
The subject invention relates to the removal of residual higher alcohols which are present from the preparation of crude higher-alkyl glycosides. The residual higher alcohols are removed via vacuum distillation with a hydroxyl-containing solvent. The purified higher-alkyl glycosides are biodegradable nonionic surfactants which are soluble and stable in highly alkaline cleaning formulations used for bottle washing, metal cleaning, textile treatment and other applications.
