Abstract
Description
technical field
[0001] The invention relates to a method for preparing 1,3-propanediol, in particular, the invention relates to a method for preparing 1,3-propanediol by direct gas-phase hydrogenolysis of glycerol. Background technique
[0002] 1,3-propanediol is one of the important monomers for the synthesis of new polyester PTT. PTT has excellent performance due to its helical structure, which combines the softness of nylon, the bulkiness of acrylic fiber and the stain resistance of polyester, plus its inherent elasticity, moderate glass transition temperature and good processing performance. The excellent properties of the fiber are integrated, so the production of 1,3-propanediol has been widely concerned (Petrochemical Industry, 2006, 35, 597). In addition, 1,3-propanediol is also used in food, pharmaceutical, cosmetics, antifreeze and other industries.
[0003] There are many processes for the production of 1,3-propanediol. At present, the processes widely used in ...
