Embodiment 1
[0021] The production technique of described further purification tripentaerythritol comprises the following steps:
[0022] Step 1: adding the crude product of tripentaerythritol with a content of 80%, ash content of 2%, and color number 6# prepared by the above preparation process into a solvent tank;
[0023] Step 2: Add an organic solvent into the solvent tank in Step 1 and stir for 10-90 minutes, the stirring temperature is controlled at 50-120°C, and the mass ratio of tripentaerythritol to organic solvent is 1:3;
[0024] Step 3: Transport the mixture in the solvent tank in step 2 to a precision separation device, and transport the separated acetals, alcohols, and formates to the tripentaerythritol hydrolysis, decolorization and crystallization processes, and separate them through the tripentaerythritol separation process The crude product of tripentaerythritol, the filtered liquid is sent to the desolventizing tower, and the solvent is recycled;
[0025] Step 4: Send t...
