| titleOfInvention | Sucrose polyethers polyalcohol and preparation method thereof |
| abstract | The invention belongs to polyether polyol synthesis technical fields, and in particular to a kind of Sucrose polyethers polyalcohol and preparation method thereof.The Sucrose polyethers polyalcohol uses liquid sugar sirup, small molecular alcohol as initiator and is polymerized under amines catalysis with oxyalkylene.The present invention uses liquid sugar sirup as raw material, reacts later period sugar residue and greatly reduces, Sucrose conversion is high；Intermediate product of the liquid sugar sirup as crystalline saccharose, it is cheap, there is explicit costs advantage；Preparation process can directly be fed with syrup tanks, thrown sugared operation without artificial, greatly improved production efficiency, reduce labor intensity.The present invention uses novel amine as catalyst, and last handling process is simple, and small molecular alcohol is added after oxyalkylene additional amount reaches 20%, it is few to post-process oxyalkylene removing, oxyalkylene high conversion rate, cost-effective and environmentally friendly, 360~450mgKOH/g of Sucrose polyethers polyalcohol hydroxyl value obtained. |
