Description
Technical field
The present invention relates to a kind of industrial process of double-(trimethoxy silicon propyl group)-amine, belong to organic chemistry filed.
Background technology
Double-(trimethoxy silicon propyl group)-amine is a kind of novel silane coupler for carrying six hydrolyzable active groups, this
The silane coupler of type imparts the special property of some.Double-(trimethoxy silicon propyl group)-amine can be in inorganic material
A bridge beam action is played between high-molecular organic material, be used on glass/ministry of electronics industry's composite as arrange or
The additive of size component, fluid sealant, adhesive, coating etc., is also used for glass and metal primary coat etc., can be with after use
Improve the performance such as the bending strength of product, tensile strength, elastomer modulus, cohesive force, anticorrosive.Double-(trimethoxy silicon third
Base)-amine hydrolysis rate is fast, and good water solubility, there is higher crosslink density after hydrolysis, be therefore particularly suitable for as filler surface
Processing and the pre- preservative treatment of metal.The country generally utilizes high pressure ammoniated industrialized production γ-aminopropyl trimethoxy silicon now
Alkane, and accessory substance pair-(trimethoxy silicon propyl group)-amine separating-purifying, in the market are had into double-(trimethoxy silicon propyl group)-amine
Sale of finished goods, but the product of this method synthesis is there is two hydrolysates and Yield comparison of aminopropyl trimethoxysilane are low,
With the increase of the market demand and the raising of product quality requirement, the product that this method obtains can not meet customer need, this
Patent mainly provides a kind of production method of yield compared with the advantages that high, cost is low, energy consumption is small, accessory substance is few, easy industrialized production.
The content of the invention
It is an object of the invention to：There is provided a kind of product yield compared with it is high, cost is low, energy consumption is small, accessory substance is few, easy industrialization
The industrial process of double-(trimethoxy silicon propyl group)-amine of production.
The technical scheme is that：
A kind of industrial process of double-(trimethoxy silicon propyl group)-amine, it is characterised in that：It comprises the following steps：
1）, in the reactor with stirring, drying tower (anhydrous magnesium chloride), thermometer and measuring tank, first with nitrogen will react
Put into quantitative aminopropyl trimethoxysilane and magnesium powder after air in device drains, under the conditions of convention stir successively, and to meter
Quantitative r-chloropropyl trimethoxyl silane and methanol are put into measuring tank；Started to warm up after the completion of feeding intake；
2）, after kettle temperature rises to 63 DEG C, by the r-chloropropyl trimethoxyl silane in measuring tank and methyl alcohol mixed liquor be slowly added to
Kettle temperature is kept in reactor, in fill process between 63 DEG C ~ 65 DEG C；
3）, r-chloropropyl trimethoxyl silane and methyl alcohol mixed liquor charging after the completion of, continue reaction 6 hours after, keep the reaction temperature
Degree distills out a small amount of methanol in reaction system under -0.098Mpa vacuum conditions, and nitrogen is vented to normal pressure after the completion of distillation, after
After continuous reaction 4 hours, obtain, double-(trimethoxy silicon propyl group)-amine crude product；Then cool；
4）, after kettle temperature is down to 50 DEG C, with closed filter under nitrogen protection to double-(trimethoxy silicon third of gained
Base)-amine crude product filtered, and gained filtrate is double-(trimethoxy silicon propyl group)-amine finished product；Gained filter residue is washed with hexamethylene
Wash, after washing lotion directly reclaims hexamethylene under the conditions of 85 DEG C, be after remnants hexamethylene is distilled out under the conditions of -0.098Mpa
Lotion product；Gained filter residue adds a small amount of hydrochloride aqueous solution and is stirred, and carrying out vacuum at 110 DEG C after stirring does
After dry 5 hours；Pack or be put into drying tower when drier is continuing with.
The chemical equation of the present invention is as follows：
。
The principle of the present invention
The present invention is added in r-chloropropyl trimethoxyl silane and aminopropyl trimethoxysilane course of reaction in magnesium powder progress
With, because simple magnesium powder and aminopropyl trimethoxysilane hydrochloric acid reactant salt are slow, and aminopropyl trimethoxysilane hydrochloric acid
Salt remains the progress that can hinder reaction in reaction system, is catalyzed so adding a small amount of methanol in system, and magnesium powder is first
First react to obtain magnesium methoxide with methanol, then magnesium methoxide carries out anti-with the aminopropyl trimethoxysilane hydrochloride in reaction system
Should, when react 6 it is small when or so in rear system most raw material be converted into double-(trimethoxy silicon propyl group)-amine vacuum distillation
The methanol gone out in system, then distill out methanol and be vented with nitrogen to normal pressure and continue the r-chloropropyl trimethoxyl silicon that makes unreacted complete
Alkane and aminopropyl trimethoxysilane are reacted, and distill out methanol primarily to avoiding magnesium methoxide residual in the product to production
Quality and use have an impact, and for the product content of this kind of method synthesis more than 99%, yield can reach more than 98%.
The advantage of the invention is that：
Invention can be reacted under certain condition by r-chloropropyl trimethoxyl silane and aminopropyl trimethoxysilane, again
Magnesium powder can be made, and reactivity more gently avoids that security incident occurs under this condition with a small amount of methanol, and the crude product of synthesis only needs
Distill out low boiling, avoid product from being lost in still-process, and byproduct of reaction magnesium chloride can regard drier use or
Person takes out, come that double-(trimethoxy silicon propyl group)-amine yield of the invention synthesized is higher relative to prior art and product quality more
It is stable, and the advantages such as cost is low, technique is simple, accessory substance is few, equipment requirement is low, and easy industrialized production.
