Abstract
The invention discloses a catalyst produced through water atomization and a manufacturing method thereof. The catalyst is prepared by melting a cathode electrolytic copper plate serving as a primary raw material at high temperature, performing high water pressure spray atomization, precipitation, high-temperature drying oxidization, selection and ball milling oxidization on the copper plate. Besides the characteristics of multiple pores, and large specific surface area of a traditional elemental sheet copper powder catalyst, the catalyst also has the property of containing three element components, namely copper, cuprous oxide and copper oxide. Due to the characteristics of multiple pores, sheet shape and large specific surface area, absorption and contact area between the catalyst and silica powder are increased, more Si and Cu alloy and eta phase can be formed, and the reaction activity of a contact is improved. The disadvantages that the content of S in the three-element copper catalyst produced by a chemical method using CuSO4.5H2O as a raw material is relatively high and the S does harm to producers, users and environments are overcome. The catalyst is continuous in production way, good in controllability and stable in quality.
Description
Technical field
Copper powder catalyst involved in the present invention and manufacturing approach thereof are specifically related to a kind of novel copper powder catalyst and manufacturing approach used when producing organic silicon monomer with water atomization.
Background technology
Organosilicon is used very extensively as " industrial monosodium glutamate "; Its organosilicon downstream and converted products extensively apply to chemical industry, light industry, weaving, medical treatment, building, field such as electric; And be accompanied by increasing of organosilicon downstream product kind and quantity thereof, its application also will constantly be expanded and developed.
Organic silicon monomer is the basis of organosilicon industry, and the level of production of monomer has directly reflected the level of organosilicon industrial development.Organosilicon products such as preparation silicone oil, silicones, silicon rubber all need organic silicon monomer, can produce a variety of organosilicon products by several kinds of monomers.The kind of organic silicon monomer mainly contains: thousands of kinds more than of methylchlorosilane, phenyl chlorosilane, methyl ethylene chlorosilanes etc.; Wherein have only methylchlorosilane the most important at this; Its consumption accounts for more than 90 of whole monomer consumption; And in the product of methylchlorosilane, principal product is exactly a dimethyldichlorosilane.The production method of methylchlorosilane has: discrimination method, replace to send out, RMgBr method, organo-metallic compound method and direct synthesis technique.
At present; The mode of commercial production methylchlorosilane monomer mainly is a direct synthesis technique; It is to be urged under the condition helping of copper catalyst by chloromethanes and silica flour accomplishing, but the reactional equation simple table is shown:
.At this, catalyst occupies the effect of particular importance and the most effectively is exactly copper catalyst in direct synthesizing methyl-chloro-silane, if there is not copper catalyst, and CH
3Cl need more than 350 ℃ could with Si powder reaction, and main what generate is not the dimethyldichlorosilane that needs but trichlorosilane.Like this, reaction just equals invalid.
Different copper powder catalysts is in the synthetic reaction of organic silicon monomer; Because its physical behavior; More different with the chemical property component like pattern, size, pine dress than, specific area, to difference and difference are all arranged the selectivity of the activity of its synthetic reaction, diformazan, reaction time etc.At present, use more copper powder catalyst to have: the ternary copper powder catalyst of sheet simple substance copper powder catalyst, protochloride copper powder catalyst, partial oxidation.Wherein, use the simple substance copper powder to make catalyst, it is low to show as reactivity, the diformazan poor selectivity, and reaction time is short; And stannous chloride is made catalyst, is prone to generate SiCl
4, increased and Me
3The degree of difficulty that SiCl separates, the easy moisture absorption of stannous chloride is rotten in addition and the chance phototropic, shortcomings such as shelf stability difference; It is active high for the ternary copper powder catalyst of partial oxidation, induction period short, even need not through just can changing normal reaction over to induction period, and selectivity is good; Diformazan content in the product is reached about 90%; Reaction time is long, is fit to serialization and produces use, and consumption is few; Can lack with a lot of than other Cu-series catalysts, can reduce the synthetic production cost of organic silicon monomer like this.This shows, the ternary copper powder catalyst of partial oxidation be present result of use best, also be to use the most general organic silicon monomer synthetic catalyst.At present, the ternary copper powder catalyst of partial oxidation mainly be through chemical method or and the mode that combines of physical method obtained: it is to use CuSO
