Embodiment 1a
[0058] The application provides a microchannel reaction system, which is applicable to the preparation of epoxy compounds, see figure 1 , including mixer 1, microchannel reactor and finished product tank 2.
[0059] The mixer 1 can be a microchannel mixer or a homogeneous emulsification pump, both of which are commonly used by those skilled in the art. In this embodiment, a homogeneous emulsification pump is specifically used as an example for illustration. Epoxy compounds, reaction initiators and other materials are strictly designed to control the corresponding molar ratios according to the molecular design of the target product. They are mixed into a mixture by mixer 1. Other materials can include materials used to promote reactions such as homogeneous catalysts, or can be are other auxiliary raw materials, which can be adjusted according to the desired product. The microchannel reactor includes a microchannel preheating section 3 and a microchannel reaction section 4, and...
Embodiment 1b
[0076] A kind of microchannel reaction system, the difference with embodiment 1a is, see Figure 4 , the microchannel reaction section 4 of this embodiment is formed by parallel connection of two sets of the same series structure as that in embodiment 1a, thereby increasing the preparation path and increasing the output of epoxy compounds under the premise of ensuring sufficient reaction.
Embodiment 1c
[0078] A kind of microchannel reaction system, the difference with embodiment 1a is, also be provided with heterogeneous catalyst in the microchannel reaction section 4 of present embodiment, heterogeneous catalyst exists in microchannel reaction section 4 internal memory with solid form In one or more process microchannels, or as a coating form of one or more process microchannel walls existing in the reaction section 4 of the microchannel. In this embodiment, the heterogeneous catalyst is specifically located in each process microchannel as an example for illustration.
