Method for distilling hexamethylcyclotrisiloxane
The invention relates to an improved distillation method wherein hexamethylcyclotrisiloxane is isolated from a crude blend thereof by mixing the crude blend with a hydrocarbon co-solvent having a normal boiling point of 125 DEG C. to 150 DEG C. and distilling the resulting mixture in an apparatus ha...
