Caprolactam (aminocaproic lactam, 2-oxohexa-methylenimine, CAS No. 105-60-2), the monomer used in the production of nylon-6, was selected and testing initiated by the Carcinogenesis Testing Program, National Cancer Institute (now part of the National Institute of Environmental Health Sciences/National Toxicology Program) because nearly one billion pounds per year are produced, because of the wi...

The effects of a series of caprolactam derivatives with central depressant, convulsant or muscle relaxant activity were investigated upon gamma-aminobutyric acid (GABA) receptor-ionophore binding to rat brain membranes using [3H]GABA, [3H]GABA, [3H]muscimol and [35S]-tert.-butylbicyclophophorothionate ([35S]TBPS) as ligands, and GABA responses in mouse spinal cord neurones in dissociated cell c...

Strong final state interaction (FSI) effects can play a central role in the Standard Model prediction of weak K → 2π matrix elements. Here, I discuss how FSI's affect the direct CP violation parameter ε ′ /ε by solving the Omnès problem for the necessary K → 2π amplitudes. The main results of this analysis have been reported in a previous paper 1 and are further discussed in Refs. 2,3. The resu...

The process of dehydration of glucose to 5-hydroxymethylfurfural (HMF), using caprolactam-lithium chloride (CPL/LiCl) as a solvent, was investigated. Dual-wavelength ultraviolet spectrophotometry provides a new approach for the determination of glucose conversion rate and yield of HMF. Experiments were performed to demonstrate the accuracy and precision of this method. Various reaction paramete...
