| titleOfInvention | Organic silicon coupling agent containing beta-dicarbonyl and preparation method thereof |
| abstract | The invention provides an organic silicon coupling agent containing beta-dicarbonyl, which belongs to the field of organic chemical synthesis. As the organic coupling agent has a beta-dicarbonyl functional group, the dicarbonyl in the structure has a coordination chelating function, is conductive to generation of coplanar acting force and increase of adhesive property, thereby further solving the application problem that fluorubber and fluorosilicone rubber are difficult to adhere; and the organic silicon coupling agent can be used for preparing special silicon oil and silicon resin. The preparation method of the organic silicon coupling agent comprises the following steps of reacting a compound containing the beta-dicarbonyl with allyl chloride under the catalysis of potassium carbonate to synthesize an allyl compound containing the beta-dicarbonyl, and then performing addition with siloxane under the catalysis of a platinum metal complex. The preparation method is simple in process and post-treatment, convenient to operate, high in yield, low in cost and easy for industrialization; and since the allylated beta-dicarbonyl compound is catalyzed by potassium carbonate, the traditional high-temperature reaction of allylic alcohol under catalysis of a high-toxicity precious metal is avoided, energy consumption is reduced, the operation is facilitated and the cost is reduced. |
