Glikoliza odpadów poliuretanowych. Cz. I, Środki glikolizujące i katalizatory

摘要: The subject of this review (25 references) is glycolysis, being one the most important chemical processes, which could be applied in feedstock recycling polyurethane waste. reactions transesterification urethane and urea bonds [equation (1) (2)] were presented introduction. Important running during complex glycolysis process [equations (3)-(7)], leading to products' mixture containing polyols or compounds similar structure but methane bonds, low-molecular weight mono- dicarbamates, amines oligomers [formula (1)], discussed. often used agents, i.e. aliphatic oligomerols at least two hydroxyl groups, described. Three main groups catalysts process, metal salts hydroxides (II)], organometallic (III)-(VII)] characterized. effects conditions on compositions products
