Abstract

POSTOPEK ZA PROIZVODNJU LAKTULOZE. Pri proizvodnji laktuloze pripravimo alkano vodno raztopine laktoze in boraksa in segrevamo pri temperaturi nad 80 C. Laktulozo odločimo iz nastalih pretvorbenih produktov. Razen boraksa ne dodamo alkalizirnega materiala k raztopini. Pretvorbo vršimo pri pH 8,3. Da vzdržujemo natrijeve ione v proizvodnem ciklu lahko proizvajamo boraks v vodni raztopini borove kiseline in že istočasno z laktozo, medtem ko prenesemo natrijeve ione iz raztopine pretvorbenih produktov v raztopino borove kisline z elektrodializo. Alternativno pa natrijeve ione lahko odstranimo iz raztopine pretvorbenih produktov kolikor mogoče zlahka, s pomočjo šibko kislega ionskega izmenjevalnika in šele za tem s pomočjo bolj močno kislega ionskega izmenjevalnika. Šibko kisli ionski izmenjevalnik regeneriramo z borovo kislino, tako da se ponovno tvorbi boraks.PROCEDURE FOR LACTULOSE PRODUCTION. In the production of lactulose, an alkane aqueous solution of lactose and borax is prepared and heated at a temperature above 80 C. Lactulose is separated from the resulting conversion products. Except borax, no alkalizing material is added to the solution. The conversion is performed at pH 8.3. To maintain sodium ions in the production cycle, borax can be produced in aqueous boric acid solution and already simultaneously with lactose, while sodium ions are transferred from the conversion products solution to the boric acid solution by electrodialysis. Alternatively, sodium ions can be removed from the solution of the conversion products as easily as possible, by means of a weakly acidic ion exchanger and only then by means of a more strongly acidic ion exchanger. The weakly acidic ion exchanger is regenerated with boric acid so that borax is formed again.
