Process for converting octamethylcyclotetrasiloxane to decamethylcyclopentasiloxane

摘要

Method for producing decamethylcyclopentasiloxane (cyclic pentamer) from octamethylcyclotetrasiloxane (cyclic tetramer) by heating said cyclic tetramer in the presence of an aqueous hydrochloric acid solution and a salt of a protonated amine having at least one nitrogen- bonded monovalent hydrocarbon group having 5 to 14 carbon atoms.
