Task: Translation
Input (Czech): Riešenie sa týká sposobu přípravy 3-oxapentandialu.  Podstatou riešenia je, že 1,5-  -dihydroxy-3-oxa-pentan v parách sa dehydrogenuje  na katalyzátore z médi, striebra,  zinku, oxidu meďnatého, oxidu strieborného,  oxidu zinočnatého, oxidu barnatého, aletm  solí, obsahujúcich meďnaté, strieborné,  zinočnaté a barnaté katióny alebo dvojchromanové  anióny jednotlivo alebo v ich  zmesi pri teplote 200 až 550 °C. Po ukončení  reakcie sa 3-oxa-pentandial oddělí z reakčnej  zmesi destiláciou. Riešenie može  nájsť uplatnenie v organické] chemii a v  chemii biopolymérov, ako aj v enzýmovom  inžinierstve pri príprave imobilizovaných  biokatalyzátorov.
Output (English): The present invention relates to a process for preparing 3-oxapentanedial.  The essence of the solution is that 1.5-  -dihydroxy-3-oxa-pentane in vapor is dehydrogenated  on a catalyst from medium, silver,  zinc, copper oxide, silver oxide,  zinc oxide, barium oxide, aletm  salts containing copper, silver,  zinc and barium cations or dichromates  anions individually or in them  at a temperature of 200 to 550 ° C. After completion of  of the reaction, 3-oxa-pentanedial is separated from the reaction  by distillation. Solution can  find application in organic] and v  chemistry of biopolymers as well as in the enzyme  engineering in the preparation of immobilized  biocatalysts.
