Claims
- 1. A process for the performance of reactions between alkyl halides and tertiary amines wherein the reaction is carried out in a silicone oil, the viscosity of which is from 40 to 20,000 centistokes at 25.degree. C.
- 2. The process of claim 1, wherein the alkyl halide is a methyl halide.
- 3. The process of claim 1, wherein the silicone oil is selected from the group consisting of hexamethyldisiloxane, hexaethyldisiloxane, hexakis (2-ethylbutoxy)-disiloxane, 1,3-dimethyl-1,3-diphenyldisiloxane, 1,1,3,3-tetraphenyl-1-3-dimethyldisiloxane, 1,1,5,5,-tetraphenyl-1,3,3,5-tetramethyltrisiloxane, 1,1,3,5,5,-pentaphenyl-1,3,5-trimethyltrisiloxane, polydimethylsiloxane, polydimethyldiphenylsiloxane, polymethylphenyldiphenyldisiloxane, and polydiphenylsiloxane.
- 4. The process of claim 1, wherein the silicone oil is a silicic acid ester substituted by silyl groups.
- 5. the process of claim 1, wherein the separation of the reaction product or products is performed by means of a solvent which is not soluble in the silicone oil.
