Synthesis technology and application status of 2,2,4,4-tetramethyl-1,3-cyclobutanediol
The properties,synthesis technology and application status of 2,2,4,4-tetramethy-1,3-cyclobutanediol(CBDO) were introduced.The polyesters which had higher glass transition temperature,good weather resistance and hydrolysis resistance could be synthesized with CBDO as monomer.The preparation of CBDO was divided into 3 steps:isobutyric acid or isobutyric anhydride was pyrolyzed into dimethylketene,dimethylketene was dimerized to form 2,2,4,4-tetramethyl-1,3-cyclobutanediol,and then the intermediate was hydrogenated for CBDO.At present,the synthesis and application technologies are monopolized by Eastman Chemical Company,USA.
