Pyrrolidine is prepared industrially by the reaction of 1,4-butanediol and ammonia at a temperature of 165–200 °C and a pressure of 17–21 MPa in the presence of a cobalt-and nickel oxide catalyst, which is supported on alumina.
[3] The reaction is carried out in a tubular reactor which is packed with the solid catalyst. The latter is arranged as a fixed bed and the reaction is carried out in the vapor phase. Product yields of 75–85% are reached. After subsequent distillation and purification, the desired 2-pyrrolidone is obtained with a purity of 99.5%. [3]
Ceftobiprole has shown in vitro antimicrobial activity against a broad range of Gram-positive and Gram-negative pathogens. Among the Gram-positive pathogens, ceftobiprole has demonstrated good in vitro activity against methicillin-resistant Staphylococcus aureus, methicillin-susceptible Staphylococcus aureus and coagulase-negative staphylococci, as well as against strains of methicillin ...
4-Pyrrolidinylpyridine is an organic compound with the formula (CH 2) 4 NC 5 H 4 N. The molecule consists of a pyrrodinyl group ((CH 2) 4 N-) attached via N to the 4-position of pyridine. It is a white solid. The compound has attracted interest because it (pK a = 9.58) is more basic than dimethylaminopyridine (pK a = 9.41). [1] It is a popular ...
Pyroglutamyl-peptidase I (EC 3.4.19.3, also known as Pyrrolidonyl peptidase, is an enzyme (a cysteine peptidase) found in bacteria, plants and animals.. It can be used to distinguish certain Streptococcal organisms.
