Abstract

Postupak za proizvodnju tietanamina. 2.1. Poznati postupak za proizvodnju tietanamina sa opštom formulom I u kojoj R1-R4 imaju značenje dato u opisu, pri kojom se tietanoni sa opštom formulom II kondenzuju sa derivatima amina, posle čega se dobijeni derivati tietanamina redukuju, imaju nedostatak vrlo malih prinosa. 2.2. Time, što se kondenzacija sprovodi kondenzacijom u autoklavu pri temperaturi od preko 80В°C, preporučljivo preko 100В°C, u prisustvu jedne pomoćne baze, čija konjugovana kiselina ima vrednost pKs od 1 do 4, pa se redukcija posle toga sprovodi sa natrijum- ili litijum borhidridom i jednim aktivatorom, postiže se vrlo uspešno da se do sada nezadovoljavajući prinosi dobijenih trietanamina sa opštom formulom I dobijaju sa visokim prinosima. Kao pomoćna baza preporučljivo se može primeniti i kiselinska adiciona so derivata amina. 2.3. Medjuproizvodi u proizvodnji dipeptidnih sredstava za zasladjivanje (sladila)
