| titleOfInvention | Amino-1,2-propanediol purification device and production method thereof |
| abstract | The invention discloses an amino-1,2-propanediol purification device and a production method thereof. The purification device comprises an elevated tank, an ammonification kettle, a deamination and dehydration kettle, a finished product distillation kettle and a Roots vacuum set which are connected through pipelines in sequence, wherein the finished product distillation kettle is connected with a front distillation tank and a finished product tank through a second condenser; the front distillation tank and the finished product tank are connected in parallel, and are respectively communicated with the Roots vacuum set. The production method comprises the following steps of: respectively preparing ammonia hydroxide, chlorinated glycerol and a catalyst according to a proportion; performing an ammonolysis reaction by the ammonia hydroxide, chlorinated glycerol and catalyst in the ammonification kettle, namely feeding an ammonified material into the deamination and dehydration kettle for distillation, and separating salt; filtering the distilled material, feeding the material into the finished product distillation kettle for re-distillation; and condensing the distilled material, and feeding into a finished product tank. |
