Abstract[English]
The present invention relates to the synthesis of di(hydroxymethyl)tetrahydrofuran (DHMTHF) and the preparation of trans-enriched mixtures of DHMTHF. The invention further refers to polyester polyols which are obtained by reaction of cis/trans DHMTHF mixtures with a dicarboxylic acid. The invention further relates to polyurethanes and compositions containing a polyester polyol comprising DHMTHF, in particular to such polyurethane-containing (adhesive) compositions.[French]
La présente invention concerne la synthèse de di(hydroxyméthyl)tétrahydrofurane (DHMTHF) et la préparation de mélanges trans-enrichis de DHMTHF. L'invention concerne en outre des polyols de polyester qui sont obtenus par réaction de mélanges cis/trans DHMTHF avec un acide dicarboxylique. L'invention concerne en outre des polyuréthanes et des compositions contenant un polyester polyol comprenant du DHMTHF, en particulier de telles compositions contenant du polyuréthane (adhésif).
