Preparation method of 2-cyanoethyl trimethoxy silane

The invention discloses a preparation method of 2-cyanoethyl trimethoxysilane, which comprises the steps that 2-cyanoethyl trichlorosilane is added into a reaction container, methanol is dropwise added into a reaction system, nitrogen is introduced for bubbling so as to enable hydrogen chloride gas generated by reaction to be timely moved out of the reaction system, the reaction container is provided with condensing equipment in a matched manner, the condensing equipment enables methanol steam to be liquefied and flow back to the reaction system, after the reaction is finished, obtained reaction liquid is subjected to reduced pressure distillation, fractions are collected, and the 2-cyanoethyl trimethoxy silane product can be obtained. The method has the advantages that the hydrogen chloride generated in the preparation process of the 2-cyanoethyl trimethoxy silane can be effectively removed on the premise of not increasing additional working procedures and materials, so that side reactions are reduced, and a high-purity target product can be obtained through rectification.

Catalyst for use in production of epoxide, method for producing the catalyst, and method for producing epoxide

To provide an epoxide-production-use catalyst that is suitably used for producing an epoxide by partial oxidation of an unsaturated hydrocarbon, a catalyst in accordance with the present invention is obtained by fixing gold fine particles to a carrier containing an oxide containing at least one of titanium and zirconium, and has an acid quantity of not more than 0.1 mmol/g determined by the NH3-TPD method. Such a catalyst for epoxide producing use can be produced by, for instance, fixing gold fine particles to a carrier having an acid quantity of not more than 0.15 mmol/g. The catalyst for epoxide producing use arranged as above is preferably used as a catalyst in partial oxidation of an unsaturated hydrocarbon to produce a corresponding epoxide.
