Abstract

Методът се използва в химическата промишленост за получаване на аспартоилсъдържащи дипептиди, използвани като подсладители. По метода се получава n-формил-l-аспарагиновият анхидрид при използването на минимален излишък от мравчена киселина. Към реакционната смес се прибавя оцетен анхидрид и с3-с6 вторичен алкохол за свързване излишъка от мравчената киселина. Получената реакционна смес, съдържаща n-формил-l-аспарагиновия анхидрид, е подходяща за използване при следващи реакции, без да се модифицира. 14 претенцииThe method is used in the chemical industry to obtain aspartoyl-containing dipeptides used as sweeteners. The method yields n-formyl-l-aspartic anhydride using a minimal excess of formic acid. Acetic anhydride and C3-C6 secondary alcohol were added to the reaction mixture to bind excess formic acid. The resulting reaction mixture containing n-formyl-l-aspartic anhydride is suitable for use in subsequent reactions without modification. 14 claims
