Laurinlactam – Wikipedia

A lactam is a cyclic amide, formally derived from an amino alkanoic acid. The term is a portmanteau of the words lactone + amide. Greek prefixes in alphabetical order indicate ring size: α-Lactam (3-atom rings)β-Lactam (4-atom rings)γ-Lactam (5-atom rings)δ-Lactam (6-atom rings)ε-Lactam (7-atom rings) … Skatīt vairāk General synthetic methods exist for the organic synthesis of lactams. Beckmann rearrangement Lactams form by the acid-catalyzed rearrangement of oximes in the Beckmann rearrangement Skatīt vairāk • Lactams can polymerize to polyamides.

Le cycle β-lactame appartient à divers antibiotiques, tels la pénicilline. Ces antibiotiques sont appelés pour cela antibiotiques β-lactamine. Ces antibiotiques agissent par inhibition de la synthèse de la paroi cellulaire de la bactérie. henry mintzberg role taxonomy

Tīmeklis2024. gada 10. dec. · A lactim is a cyclic carboximidic acid compound characterized by an endocyclic carbon-nitrogen double bond. They are formed when lactams undergo tautomerization. Reactions Lactams can polymerize to polyamides.

La denumirea lactamelor, prefixele indică câți atomi de carbon (fără gruparea carbonil) fac parte din ciclu: β-lactama (2 atomi de carboni, fără cel de la carbonil, deci 4 atomi aparținând ciclului), γ-lactama (trei atomi de carbon), δ-lactama (patru atomi de carbon). TīmeklisLaurinlactam ist ein praktisch wasserunlöslicher, in technischer Qualität meist beige gefärbter und in reinem Zustand (Monomerqualität mit 99,9 % Reinheit) weißer kristalliner Feststoff, der in vielen organischen Lösungsmitteln, z. B. 1,4-Dioxan, Benzol, Cyclohexan, löslich ist. henry mintzberg quotes
