Title: Method of preparing cyclic organohydrosiloxane
Inventor: SUTEIIBUN KERII FURIIBAAN
IPC: C07F7/21
Filed: 1993-08-30
Abstract: PURPOSE: To effectively obtain compounds in a high yield useful as a surface-active agent or the like by bringing specific organohydrodihalosilane in contact with a prescribed quantity of water and treating the mixture under specific conditions.  
     CONSTITUTION: Organohydrodihalosilane of formula I (wherein R represents 1-20C alkyl or the like; X represents halogen) is brought into contact with a nearly stoichiometric quantity of water at a temperature of from 0°C to 50°C to obtain a first mixture. By distilling the mixture, a second mixture containing cyclic organohydrosiloxanes and short-chain polyorganohydrosiloxanes is recovered. By bringing the second mixture in contact with water, the said short- chain polyorganohydrosiloxanes are polymerized until long-chain polyorganohydrosiloxanes is obtained to obtain a third mixture. By distilling the third mixture, the cyclic organohydrosiloxanes are recovered to obtain the objective compounds.
