| titleOfInvention | Method for the preparation of organopolysiloxane free from acid catalyst residue |
| abstract | Proposal is given of a method for the preparation of an organopolysiloxane highly freed from any trace amount of the residue of sulfuric acid or fuming sulfuric acid by the siloxane rearrangement reaction of organosiloxane oligomers into equilibirium by using the acid catalyst. The inventive method comprises subjecting the reaction mixture, after completion of the reaction but before the conventional step of washing with a large volume of water to remove the acid residue, to a hydrolysis reaction of the acid residue bonded to the organopolysiloxane molecules with admixture of a limited amount of water and separating the mixture into aqueous and organopolysiloxane phases to discard the acid-containing aqueous phase. |
