Problems solved by technology

[0003] The purpose of the present invention is to provide a simple preparation method with low cost to solve the problem that the existing common silane coupling agent cannot meet the needs of special industries, and the by-products produced in the preparation of the existing common silane coupling agent are not reused. Therefore make its production cost on the high side, the preparation of the 3-(phenylamino) propyl alkoxysilane that also has impact on environmental problem simultaneously and the recycling process of by-product

Abstract

The invention relates to a preparation method of 3-(phenyl amino) propyl alkoxy silane, and recycling technology of a by-product, belonging to the technical field of organic chemistry. The preparation method comprises the steps of: using aniline and 3-chlorine propyl alkoxy silane for carrying out ammonolysis reaction to generate the solid of 3-(phenyl amino) propyl alkoxy silane and aniline hydrochloride; filtering the aniline hydrochloride; and distilling filtrate to obtain the 3-(phenyl amino) propyl alkoxy silane product, wherein the 3-(phenyl amino) propyl alkoxy silane product contains phenyl, amino, alkoxy or methyl, can provide and improve special functional properties for polyurethane material, adhesive, and reinforced phenolic composite material. The invention can be used for neutralizing treatment of the by-product aniline hydrochloride, so that the environmental pollution can be avoided, and the industrial wastewater directly enters a sewage treatment system; furthermore, aniline can be recovered and recycled, so that the production cost is reduced.

Description

Technical field [0001] The present invention involves a 3- (phenyl amin amino) propyration and the recycling and utilization process of glyphosine, which is the field of organic chemical technology. Background technique [0002] Silicane coupling agent is a very widely used chemical product. It is used in coatings, rubber, textiles, glass fiber, ceramics, electronics, pharmaceutical materials, and architecture.With the development of the chemical industry, ordinary Silicane coupling agents can no longer meet the needs of some special industries, such as polyurethane, epoxy, acrylic, phenolic and glass, metal, glass fiber, and inorganic fillers; adhesives, sealing agents, sealing sealsAdhesive, coatings, glass fiber infiltants and surface treatment agents, bottom treatment agents and casting sand binders; improve the high temperature aging performance of glass fiber enhanced phenolic composite materials.At present, customers need to be purchased from abroad when they need such sil...
