Abstract

1348372 Partially hydrophobic SiO 2 IMPERIAL CHEMICAL INDUSTRIES Ltd 18 Jan 1971 [16 Feb 1970] 7385/70 Heading C1A [Also in Division A5] Powdered SiO 2 having a surface area of at least 10 m.<SP>2</SP>/g. is rendered partially hydrophobic by treatment with (1) an anhydrous monomeric silane of formula where R is a hydrophobic group, e.g. a 1-20 C alkyl or alkenyl group or phenyl, benzyl, tolyl, cyclopentyl or cyclohexyl, which may be substituted with Cl, F, CF 3 , alkylether, or aryl ether; L is a group reactive with OH, e.g. Cl or 1-5 C alkoxy, which may be alkyl ether substituted; n is 1, 2, or 3, and one R or L may be replaced by a hydrophilic group, e.g. polyethylene oxide chain. Examples are Me 3 ClSi, Me 2 (EtO) 2 Si, Me(EtO) 3 Si, Me(vinyl)Cl 2 Si, PhCl 3 Si, n-PrCl 3 Si, Ph 2 Cl 2 Si, (R 14 )(EtO) 3 Si, (B-Cl-EtO) 3 MeSi: (2) a symmetrical siloxane or silazane, e.g. (Me 3 Si) 2 O, (Me 3 Si) 2 NH, (Me 2 - vinyl Si) 2 O; (3) a polysiloxane containing hydrophylic groups, e.g. oxyalkylene or hydroxyalkylene. It may be produced in situ using a mixture of mono, di, and trichlorosilanes. The SiO 2 preferably has a surface area of 100-400 m.<SP>2</SP>/g. and may be initially dried at 50-70‹ C. After treatment with the Si compound it may be heated in steam or N 2 at 40- 100‹ C.
