【発明の名称】ブチンジオールの合成法及び装置
Document Type and Number:
Japanese Patent JP3180113
Kind Code:
B2
Abstract:
The conversion of formaldehyde and acetylene in the presence of a suspension catalyst to butynediol is usually performed in a cascade of reactors, wherein the separation of the catalyst from the product solution takes place per individual reactor. This can be performed by filters installed in the reactor or by suitable filter apparatuses outside the reactor. A part of the catalyst present in the reactors can be drawn off and replaced by regenerated and/or fresh catalyst. The catalyst drawn off from the reactors can advantageously be fed to a regeneration. The replacement of the catalyst in the reactor can take place discontinuously or continuously. In the reactors of the cascade, a catalyst amount of 50-200 g, preferably of 75-125 g, per liter of reaction solution is used.
