Clay composition
View Patent ↗A method for pacifying the spent bed material resulting from the synthesis of organohalosilanes and halosilanes by mixing clay with spent bed material. Clay compositions containing at least 10 weight % of clay and spent bed material, as well as ceramic compositions containing spent bed material, are also provided.
1. A clay composition comprising spent bed material resulting from synthesis of organohalosilanes and halosilanes and at least 10 wt % of clay.
2. A clay composition according to claim 1 , in which the clay is present in an amount of at least 20 wt % of the clay composition.
3. A clay composition according to claim 1 , in which the clay and spent bed material are present in a weight ratio of from 3:1 to 1:3.
4. A clay composition according to claim 1 , in which water is present in an amount of from 10 to 40 wt % of the clay composition.
5. A clay composition according to claim 1 , in which the clay is selected from Fuller's Earth, bentonite, kaolin (China clay) and diatomite.
6. A clay composition according to claim 1 , which further comprises direct process residue gel resulting from neutralisation and dewatering of higher boiling point halosilanes produced by direct process reaction of silicon and methyl chloride.
7. A clay composition according to claim 2 , in which the clay and spent bed material are present in a weight ratio of from 3:1 to 1:3.
8. A clay composition according to claim 2 , in which water is present in an amount of from 10 to 40 wt % of the clay composition.
9. A clay composition according to claim 3 , in which water is present in an amount of from 10 to 40 wt % of the clay composition.
10. A clay composition according to claim 7 , in which water is present in an amount of from 10 to 40 wt % of the clay composition.
11. A clay composition according to claim 2 , in which the clay is selected from Fuller's Earth, bentonite, kaolin (China clay) and diatomite.
12. A clay composition according to claim 3 , in which the clay is selected from Fuller's Earth, bentonite, kaolin (China clay) and diatomite.
13. A clay composition according to claim 4 , in which the clay is selected from Fuller's Earth, bentonite, kaolin (China clay) and diatomite.
14. A clay composition according to claim 2 , which further comprises direct process residue gel resulting from neutralisation and dewatering of higher boiling point halosilanes produced by direct process reaction of silicon and methyl chloride.
15. A clay composition according to claim 3 , which further comprises direct process residue gel resulting from neutralisation and dewatering of higher boiling point halosilanes produced by direct process reaction of silicon and methyl chloride.
16. A clay composition according to claim 4 , which further comprises direct process residue gel resulting from neutralisation and dewatering of higher boiling point halosilanes produced by direct process reaction of silicon and methyl chloride.
17. A clay composition according to claim 5 , which further comprises direct process residue gel resulting from neutralisation and dewatering of higher boiling point halosilanes produced by direct process reaction of silicon and methyl chloride.
