Description
Technical field
The present invention relates to a kind of method for reducing Polychlorinated biphenyls content in dimethoxydiphenylsilane, wherein diphenyl two
Methoxy silane is made by diphenyl dichlorosilane alcoholysis method.
Background technology
Polychlorinated biphenyls (polychlorinated biphenyls, PCBs) is currently to endanger most serious to human environment
One of polluter, belongs to carcinogen, is easily dissolved in fat, is easily absorbed and is accumulated by human adipose tissue, causes brain
The disease in portion, skin and internal organ, and influence nerve, reproduction and immune system.Early in 1991, Chinese energy portion and Environmental Protection Agency were sent out
Cloth file, stringent control use and handle product and waste containing PCBs, and product is necessary higher than more than 50ppm containing Polychlorinated biphenyls
Processing.Promulgated on January 4th, 1998《National Hazard waste register》PCBs is listed in the 47 class hazardous wastes listed.
On May 23rd, 2001, the per pro of 127 countries and regions including Chinese Government are intended to strictly be prevented or restricted from
Use 12 kinds of persistence organic pollutants (POPs)《Convention of Stockholm》, in this 12 kinds of POPs, PCBs is once big
Measure a kind of material for using, oneself it is found that the mankind and the breeding decline of many wild animals and immune system be suppressed all with it is more
Chlordiphenyl is related, and PCBs is also the basic substance of strong carcinogen dioxin (Dioxins) product.
Dimethoxydiphenylsilane is a kind of important organo-silicon compound, available for phenyl silicone oil, phenyl polysiloxane,
The production of phenyl siloxane rubber, this kind of product have very important value for high technology industry and national defense industry.Traditional two
Phenyidimethoxysilane synthetic method is made using diphenyl dichlorosilane alcoholysis reaction, and diphenyl dichlorosilane is then
It is that legal (chlorobenzene and chlorosilane are warm at high temperature by direct method (chlorobenzene and silica flour are directly synthesized in catalyst) and pyrocondensation
Condensation) obtain, which can produce substantial amounts of Polychlorinated biphenyls accessory substance, and Polychlorinated biphenyls is once production, it is difficult to directly remove,
So can finally it be embodied in dimethoxydiphenylsilane product.Inorganic chlorine or more in dimethoxydiphenylsilane product
Chlordiphenyl content is higher, can influence its application range, and particularly some high-end fields cannot use completely.And by adding the alkali of alcohol
Metallic compound can remove the middle inorganic chlorine of dimethoxydiphenylsilane product, but for Polychlorinated biphenyls, then not have substantially
Effect.Therefore, it is particularly necessary to find a kind of method for reducing Polychlorinated biphenyls content in dimethoxydiphenylsilane.
Has the process of the various methods processing Polychlorinated biphenyls of document report.As patent US4623464 uses physical chemistry
The method being combined with biological treatment removes the Polychlorinated biphenyls in waste water；US5746926 joins more chlorine using hydrothermal oxidization method
Benzene dechlorination, reacts using aqueous sodium carbonate as medium, 300~400 DEG C, is carried out under conditions of 20~400atm, dechlorination condition compared with
It is difficult for harshness, industrial treatment.US5185488 uses metallic sodium or calcium as reducing agent, to handle more chlorine in transformer oil
Biphenyl dechlorination, but have to coordinate low-carbon alcohols (methanol), and the amount of metallic reducing agent used is the 30-40 of chlorinity in system
Times.CN1470300 reports the High-activity nano-grade alkali metal hydride for using complex catalysis method to synthesize as reducing agent, transition gold
Category compound is reaction promoter, the method for handling Polychlorinated Biphenyls in Transformer Oils.CN1016142 is reported using powdered first
Sodium alkoxide is in 250~290 DEG C of methods for destroying organic halogenation product such as Polychlorinated biphenyls in organic oil or mineral oil.EP99951 is reported
Polychlorinated biphenyls in handling insulating oil at 110~130 DEG C using particle dispersion sodium.This method needs previously prepared tiny point
Property sodium particle is dissipated, and needs more than 80% sodium grain diameter to be less than 10 μm, otherwise, without treatment effect；In addition centrifugation is passed through
Responseless sodium is separated and recovered, condition is very harsh.
Since the silicon oxygen bond in dimethoxydiphenylsilane is comparatively active, in alkali metal alcoholates (such as first under high temperature
Sodium alkoxide) under the action of can alkaline hydrolysis condensation, bring larger product to lose, and be difficult to realize industrialize.So these above-mentioned methods
Be not suitable for the Polychlorinated biphenyls in processing dimethoxydiphenylsilane.
The content of the invention
The object of the present invention is to provide one kind in a mild condition, by succinctly operating, diphenyl dimethoxy silicon is removed
The method of Polychlorinated biphenyls in alkane, can improve product quality, widen its application field.
The present invention solves above-mentioned technical problem and is adopted the technical scheme that：One kind reduces dimethoxydiphenylsilane production
The method of Polychlorinated biphenyls content, comprises the following steps in product：
S1 adds metallic sodium into the dimethoxydiphenylsilane containing Polychlorinated biphenyls, is protected under 100~105 DEG C of oil baths
After 5~6h of temperature stirring, room temperature is down to；
The pH value of S2 organic acid regulation systems is 6~8；
S3 is filtered, and rectifying, obtains dimethoxydiphenylsilane product.
By such scheme, the additive amount of the metallic sodium is 2-10 times of Polychlorinated biphenyls amount (in terms of chlorine), mole meter.
By such scheme, the additive amount of the metallic sodium is 5 times of Polychlorinated biphenyls amount (in terms of chlorine), mole meter.
By such scheme, the organic acid described in step S2 is acetic acid.
By such scheme, the dimethoxydiphenylsilane is made by diphenyl dichlorosilane alcoholysis, and is carried out
Tentatively de- dechlorination process.
By such scheme, Polychlorinated biphenyls content is reduced to 5ppm in the dimethoxydiphenylsilane product described in step S3
Below (in terms of chlorine).
By such scheme, the pH value described in step S3 is 6.5-7.5.
Dimethoxydiphenylsilane product Polychlorinated biphenyls content after such scheme is handled is reduced to below 5ppm
(in terms of chlorine).
The advantages of present invention uses above-mentioned technical proposal is：Metallic sodium can be in melting state, have at 100~105 DEG C
Sufficiently high activity, is so easy to react with the chlorine in Polychlorinated biphenyls；Acid for regulation system pH value is acetic acid, shape
Into salt be sodium acetate, will not destroy dimethoxydiphenylsilane product in follow-up distillation process and cause product to damage
Lose；The side product chlorinated sodium or sodium acetate of generation, insoluble in reaction system, easily by being filtered to remove, industrial operation is simple.
