Method for preparing mercaptosilane in virtue of thiourea process

The invention relates to a method for preparing mercaptosilane in virtue of a thiourea process, belonging to the technical field of fine chemical engineering. The method comprises the following steps:dropwise adding an alcoholic solution of thiourea into chloropropyl siloxy silane and dodecyl trimethyl phosphorus bromide, carrying out a condensation reaction and an aging reaction, and conductingstanding for layering to obtain a mercaptosilane product. According to the invention, an isomerization reaction is inhibited by adjusting reaction conditions; the consumption of thiourea is reduced; ethylenediamine is used as a neutralization initiator, so solid by-products can be greatly reduced; and a guanidine salt state can be changed, so a crude product and a salt can be better separated, operation is simplified, and yield is improved.

Method for preparing mercaptosilane coupling agent by using phase transfer catalyst

The invention discloses a method for preparing a mercaptosilane coupling agent by using a phase transfer catalyst. Sodium hydrosulfide and halogenated alkyl alkoxy silane are used as raw materials, and a hydrocarbon organic solvent is adopted as a protective agent. The method comprises the following steps: carrying out synthetic reaction on the sodium hydrosulfide in a water phase and the halogenated organosilane dissolved in the hydrocarbon organic solvent by utilizing a phase transfer catalyst, separating a reaction product organic layer after the synthetic reaction is finished, performing distillation to remove the hydrocarbon organic solvent, and carrying out reduced pressure filtration and distillation to obtain the mercaptosilane coupling agent. The synthesis reaction is relatively complete, the product quality is relatively high, the yield of the prepared mercaptosilane coupling agent is greater than or equal to 93%, and the purity is greater than or equal to 99%; the process issimple, the synthesis reaction process is easy to control, tail gas can be recycled, and the safety of organic synthesis reaction is enhanced; the reaction requires a low temperature, and low requirements on equipment; the hydrocarbon organic solvent is recyclable; and the manufacturing cost is low.

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.

Method of producing silylalkylthiols

Silylalkylthiols are produced by reacting silylalkylsulfanylsilanes with water. The silylalkylsulfanylsilanes used as starting products can be produced by reacting bil-silylalkylpolysulfanes or bis-silylalkyldisulfanes with alkali metal and chlorosilanes.

Process for the preparation of mercaptosilanes

Mercaptosilanes are prepared from haloorganylsilyl compounds and an alkali metal hydrogen sulfide in the presence of a polar, aprotic medium.
