Výhodou navrhovaného spósobu regenerácie D-glukózy z epimérizačných zmesi D-glukózy a D-manózy je, že D-glukózový roztok je vhodný pre další cyklus epimerizácie D-glu kozy zameranej na přípravu D-manózy, připadne na iné zúžitkovanle - skvasenie, při recyklizácii íónomenlčov minerálny ml kyselinami sa regeneruje tiež anilin a netoxické odpadové vody sú vhodné pre biologické čistenie·The advantage of the proposed method of D-glucose regeneration from epimerization mixtures of D-glucose and D-mannose is that the D-glucose solution is suitable for the next cycle of D-glucose epimerization aimed at the preparation of D-mannose, eventually other utilization - fermentation, aniline and non-toxic waste water are suitable for biological treatment

Příklad 1Example 1

Zmee D-glukózy (300 g), vody (900 ml), molybdénanu amonného (1,5 g), kyseliny octovej (6 ml) sa zahrieva na 95 až 100°C pó dobu 4 hodiny· Roztok sa zahustí a teplý sirupovitý zvyšok sa vleje do etanolického roztoku anilinu (900 ml 96 % etanolu a 120 ml anilínu). Roztok sa pramieša a nechá stáť pri teplote miestnosti 8 až 20 hodin· Vylúčený biely kryštalický N-fenyl-D-manozylamin (80 až 90 g) sa odfiltruje a D-manóza z něho uvolní hydrolýzou eilne kyslým iónomeničom podlá AO č. 196 996. Matečný roztok po odstráneni kryštalického N-fenyl-D-manozylaminu sa zahustí na polovičný objem, ktorý ea zriedi vodou (800 ml), potom sa přidá silné kyslý iónomenič (Ostion KS 0210) v H+-cykle (1000 ml) a zmes sa mieša pri teplote miestnosti 4 hodiny, iónomenič ea odfiltruje, premyje vodou, filtrát sa zahusti na 15 až 25 % obsah D-glukózy (refraktometrická kontrola), upraví ea kyselinou octovou na pH 4 až 6 a uskutočni sa další cyklus epimerizácie, izolácie D-manózy a regnerácia D-glukózy ako je už opisané.A mixture of D-glucose (300 g), water (900 ml), ammonium molybdate (1.5 g), acetic acid (6 ml) was heated to 95-100 ° C for 4 hours. · The solution was concentrated and a warm syrup residue Pour into ethanolic aniline solution (900 mL of 96% ethanol and 120 mL of aniline). The precipitated white crystalline N-phenyl-D-mannosylamine (80-90 g) is filtered off and D-mannose is liberated therefrom by hydrolysis with an acidic ion exchanger according to AO no. 196 996. After removal of the crystalline N-phenyl-D-manozylamine, the mother liquor is concentrated to half volume, which is diluted with water (800 ml), then a strong acid ion exchanger (Ostion KS 0210) in H + -cycle (1000 ml) is added. and the mixture is stirred at room temperature for 4 hours, the ion exchanger ea is filtered off, washed with water, the filtrate is concentrated to a 15-25% D-glucose content (refractometric control), adjusted to pH 4-6 with acetic acid and a further epimerization cycle is performed. isolating D-mannose and recovering D-glucose as described above.

Vynález má uplatnenie pri výrobě komerčně zaujímavej D-manózy, ktorá ea využívá v chémii a biochémii sacharidov.The invention has application in the production of commercially interesting D-mannose, which uses carbohydrate chemistry and biochemistry.
