| titleOfInvention | The preparation method of high-purity 2,5- hexichol amido terephthalic acid (TPA) |
| abstract | The present invention provides a kind of high-purities 2, the preparation method of 5- hexichol amido terephthalic acid (TPA), the technical solution has abandoned the intrinsic technique that DMSS and aniline AN are carried out to condensation reaction in the organic solvents such as methanol, ethyl alcohol, DMSS, aniline and cetyl trimethylammonium bromide are reacted under cobalt chloride catalysis, reaction product is mixed with PEG, hydrocinnamamide, it controls certain vacuum degree further to react, obtains the first intermediate product；On the other hand, using hydroquinone, glycerine and methyl ethyl ketone as raw material, niacin is first added dropwise and reacts certain time, then is further reacted with Sodium Hyaluronate, obtains the second intermediate product；Under vacuum conditions by the first intermediate product and the second intermediate product finally, it is reacted by molybdic acid calcium treating, finally obtains 2,5- hexichol amido terephthalic acid (TPA) finished product.2,5- hexichol amido terephthalic acid (TPA) prepared by the present invention has higher purity, and synthetic route is succinct, pollution level is smaller, has higher economic benefit. |
