  2. 1. Analysis, metabolism, effects and biological monitoring of N-methyl-2-pyrrolidone

    Author : Martin Carnerup; Avdelningen för arbets- och miljömedicin; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Yrkesmedicin; arbetsmiljömedicin; industrial medicine; Occupational health; developmental toxicity; biomarkers; metabolsim; N-methyl-2-pyrrolidone; dermal absorption;

    Abstract : N-methyl-2-pyrrolidone (NMP) is an organic solvent widely used in the industry. Irritation of the eyes and in the respiratory system has been reported after occupational exposure to low air levels of NMP. The EU has also classified it as a developmental toxicant. NMP is easily absorbed in the gastrointestinal tract and airways and through skin. READ MORE

    Abstract : The skin is a barrier which protects us against daily attacks of foreign substances. From a pharmaceutical perspective it is also an interesting delivery route with its large surface and possibility to reach the blood stream circumventing first passage metabolism. With the varied size, structure etc. READ MORE

  6. 4. Spectroscopic studies of solvation and adsorption properties of PVP

    Author : Ildikó Száraz; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : The adsorption mechanism of 1-vinyl-2-pyrrolidone (VP), poly(1-vinyl-2- pyrrolidone) (PVP) and azelaic acid on synthetic gamma-aluminium oxide surfaces was investigated using FT-IR, FT-Raman, UV, 1H and 13C NMR spectroscopy. (Liquid-solid state) As a first step the solvation of VP and PVP in solvents of varying polarity, specifically water, ethylene glycol (EG), chloroform and carbon tetrachloride, was studied.
