TH55314B - Methods for amplification and/or purification of polysiloxane hydrolyzate. - Google Patents

Abstract

DC60 (27/03/57) is neutralized by polysiloxane hydrolyzate by acting on polysiloxane hydrolyzate, which has an acidic component that is residew to carbon. And later removing carbon from the polysiloxane Operated and neutralized hydrolyzate, some samples of polysiloxane hydrolyzate. Which may have been done Is polysiloxane hydrolyzate with a hydride function group. And polydimethyl siloxane hydrolyzate Especially likely to use carbon neutralization agent is the carbon derived from bituminous coal, removing the carbon from the treated polycyloxane hydrolyzate. And was neutralized by passing carbon onto the device For the separation of solid-liquids such as plates and frames, filter press, sanding filter and post filter for fine powder removal. Neutralize polysiloxane hydrolyzate by acting on polycyloxane hydrolyzate, which contains residual acidic constituents with carbon And later remove carbon from Modified and neutralized polysiloxane hydrolyzate, some samples of polysiloxane hydrolyzate. Which may have been done Is polysiloxane hydrolyzate with a function group of hydride and polydimethyl siloxane hydrolyzate. The carbon neutralizer most likely to be used is carbon. Derived from bituminous coal Remove carbon from neutralized and neutralized polysiloxane hydrolyzate by passing carbon to solid-liquid separation equipment such as plates and frames, filters, presses, polished filters. And post filters to remove fine powder.

Claims (10)

1. The method of neutralizing polysiloxane hydrolysate involves the action of an acidic residue on the polysiloxane hydrolysate, which is then attached to the carbon, and the separation of the carbon from the neutralized polysiloxane hydrolysate. 2. The method under claim 1, in which polysiloxane hydrolysates are polysiloxane hydrolysates containing hydride functional groups or polydialkylsiloxane hydrolysates. 3. The method under claim 2, in which polydialkylsiloxane hydrolysate is polydimethylsiloxane hydrolysate. 4. The method under claim 1, which selects carbon from a group consisting of coke, charcoal, activated carbon, bituminous coal carbon, anthracite carbon, lignite carbon, wood carbon, peat carbon, and coconut shell carbon. 5. The method under claim 4, where carbon is derived from bituminous coal. 6. The method under claim 5, whereby carbon is granular bituminous activated carbon containing carbon particles of a certain size which pass through an 80-sieve but are blocked by a 270-sieve, or granular bituminous activated carbon containing carbon particles of a certain size which pass through a 12-sieve but are blocked by a 30-sieve. 7. Methods under claim 6 where the average particle size of carbon is greater than 53 microns and less than 180 microns, or the average particle size is greater than 550 microns and less than 1410 microns. 8. The method under claim 1 involves removing carbon from the treated and neutralized polysiloxane hydrolysate by passing the carbon through a plate and frame filter press and subsequently passing the filtered hydrolysate through a polishing filter to remove particulate matter. 9. A procedure under claim 1 which passes polysiloxane hydrolysate through a carbon fixation layer and filters out the neutralized polysiloxane hydrolysate to remove fine carbon. 10. The method under claim 1 involves passing polysiloxane hydrolysate to a filter saturated with one or more carbon sheets.
