Embodiment 1

[0027] Step (1): One hydrolysis reaction, mix 1L vinylsilane high boiler with 6L water, 20gNaClO 3 Mix and stir for 120min at a speed of 300r / min to fully react;

[0028] Step (2): Once filtered, the fully reacted solution was filtered for solid-liquid separation: the obtained solid residue was 2296g, after being washed twice to neutrality, the main component was analyzed and detected to be SiO 2 , the metal platinum content has been reduced to 0.69mg / t. Dry the washed solid slag at 100°C for 4 hours, and then grind it with a ball mill to a particle size below 200 mesh. It can be used as metallurgical auxiliary materials or sold to glass and cement manufacturers. . Filter gained filtrate 4330ml, and its acidity is 3.7mol / L, contains platinum 19.1mg / L in the analysis detection filtrate.

[0029] Step (3): secondary hydrolysis reaction, after mixing the water of filtrate 4330ml and 1670ml described in the step (2) to obtain a new solvent, with new 1kg vinylsilane high boiler a...

Embodiment 2

[0034] In the primary hydrolysis reaction of step (1), 1L vinylsilane high boiler is mixed with 5.4L water, 18g H 2 o 2 Mix and fully stir to make the reaction complete; for the secondary hydrolysis reaction of step (3), the filtrate obtained in step (2) is added with water to obtain 5.4L new solvent, and with new 1kg vinylsilane high boiler and 18g H 2 o 2 Mix and fully stir to make the reaction complete; the resin in step (5) is adsorbed, and the filtrate obtained in step (4) is diluted 8 times, and the metal platinum therein is adsorbed by an anion exchange resin; the solid slag obtained in step (5) is 3 Dry it at 100°C for 6 hours, and then grind it with a ball mill to a particle size below 200 mesh. It is used for the production of glass or as a metallurgical auxiliary material. All the other operations are the same as in Example 1.

Embodiment 3

[0036] In the primary hydrolysis reaction of step (1), with 1L vinylsilane high boiler and 7L water, 16g HNO 3 Mix and fully stir to make the reaction complete; for the secondary hydrolysis reaction of step (3), the filtrate obtained in step (2) is added with water to obtain 7L new solvent, and with new 1kg vinylsilane high boiler and 16g H 2 o 2Mix and fully stir to make the reaction complete; the resin in step (5) is adsorbed, and the filtrate obtained in step (4) is diluted 12 times, and the metal platinum therein is adsorbed by an anion exchange resin; the solid slag obtained in step (5) is 3 Dry it at 100°C for 8 hours, and then grind it with a ball mill to a particle size below 200 mesh. It is used for the production of glass or as a metallurgical auxiliary material. All the other operations are the same as in Example 1.

Abstract

The invention discloses a method for comprehensive utilization of vinyl silane high boilers, comprising the following steps: (1) mixing and stirring vinyl silane high boilers with water and an oxidant; (2) filtering the fully reacted solution , to obtain solid residue 1 and filtrate 1; (3) add water to filtrate 1, mix and stir with vinylsilane high boiler and oxidant; (4) filter the fully reacted solution to obtain solid residue 2 and filtrate 2; (5) Wash the solid residue 1 and the solid residue 2 twice to obtain the solid residue 3; (6) After diluting the filtrate 2, adsorb the platinum group metals in it through an anion resin; The resin is desorbed to recover the platinum group metals therein. The method of the present invention has the advantages of simplicity, small amount of reagents, low production cost, green energy saving and environmental protection, etc., can recycle platinum group metals, and solid slag can also be used to produce glass or as metallurgical auxiliary materials, realizing real resource recycling. .

Description

technical field [0001] The invention belongs to the technical field of comprehensive utilization of organosilicon by-products, and in particular relates to a method for comprehensive utilization of vinyl silane high boilers. Background technique [0002] As an important new polymer material, organosilicon has been widely used in many fields. Among them, vinyl silane is an important basic raw material in the silicone industry, and a large number of by-products will be produced during its production process. Among these by-products, those with a boiling point higher than 80°C are vinyl high boilers. With the increasing demand for new polymer materials, the production of silicones is also increasing year by year, which also leads to a simultaneous increase in the production of high boilers. Due to the complex composition of high boilers, difficulty in separation, low utilization value, strong corrosiveness, difficulty in storage and use, serious environmental protection and sa...
