First, N-y-chloropropylpentafluoropropion- amide (Sa) and N-y-chloropropylheptafluoro- butyramide (8b) were prepared respectively by direct condensations of the corresponding acid chlorides with chloropropylammonium chloride in the presence of triethylamine. Al- though N-y-chloropropylperfluorooctanam...
acid and acryloyl chloride by addin g reactant and distilling resultant continuousely,the demand of inhabitor could be decreased,so as to increase the yield and purity of the product.When the mole ratio of acrylic acid and phosphorous oxychloride is 1∶1,the yield of acryloy l chloride is ...
This review discusses on extraction methods of fatty acids from food samples and fatty acid methyl esters (FAME) preparation methods for GC–MS analysis. There are many biological functions associated with the fatty acids, including they act as primary constituents of cell membranes, an energy ...
(Meck et al.2006; Battioui2013; Kotsiopoulos and Harrison2017). It is reported in some cases acid mine drainage (AMD) of coal tailing dams contained an amount of sulfates, nitrates, chlorides and heavy metals higher than the average value defined by the World Organization of Health (WHO) ...
