| titleOfInvention | Method for treating crude bis--ß-hydroxyethyl terephthalate |
| abstract | 1,134,949. Purifying bis-#-hydroxyethyl terephthalate. SUMITOMO CHEMICAL CO. I td. 6 May, 1966 [14 May, 1965], No. 20255/66. Heading C2C. Crude bis-#-hydroxyethyl terephthalate is purified by acting on an aqueous solution of crude bis-#-hydroxyethyl terephthalate with hydrogen gas in the presence of a platinum, palladium, rhodium, ruthenium, nickel or cobalt catalyst to reduce impurities in the solution without reducing bis-#-hydroxyethyl terephthalate. The hydrogen may be adsorbed by the catalyst before the reducing treatment. The catalysts may be employed on such carriers as active carbon, asbestos or diatomaceous earth. The product may be treated with active carbon and polymerization to polyethylene terephthalate is referred to. Examples are furnished. |
