Quantitative Analysis of Phenol and Alkylphenols in Brazilian Coal Tar
The main purpose of this work is the identification and quantification of phenolic compounds in coal tar samples from a ceramics factory in Cocal (SC), Brazil. The samples were subjected to preparative scale liquid chromatography, using Amberlyst A-27 ion-exchange resin as stationary phase. The fractions obtained were classified as “acids” and “BN” (bases and neutrals). The identification and q...
متن کاملcritical discourse analysis of two political speeches in light of bakhtins dialogism
چکیده گفتگوگری باختین نظریه ای است که به تفاوت ها احترام گذاشته و گفتگو را ارج می نهد. رشته های مختلف علوم انسانی همواره از این نظریه بهره جسته اند. با وجود این تنها مطالعات اندکی در زمینه تجزیه و تحلیل نقادانه کلام به نظریه گفتگوگری پرداخته اند. پنداشت تحقیق حاضر بر آن است که احترام به حقوق دیگران از طریق فراهم آوردن شرایط یکسان برای بیان نظریات مختلف یکی از مهمترین مشترکات تحلیل انتقادی گفتم...
15 صفحه اولCoal Tar Analysis by Lc/ms
The production of liquids from coal gives rise to complex intermediates which require detailed analysis to understand the processes occurring and to make effective use of the products. Analysis has hitherto been based on structural parameters from NMR methods (1) to give the average characteristics of the sample, supplemented by molecular information from GC and GC/MS. The gas chromatographic a...
متن کاملCoal tars and coal tar pitches.
Numerous studies, mostly case reports, have found that occupational exposure to coal tars or coal-tar pitches (coal-tar distillates) is associated with skin cancer, including scrotal cancer; workers in these studies have included patent-fuel (coal-briquette) workers, pitch loaders, workers in electrical trades, and optical-lens polishers (IARC 1985, 1987). A 1946 study in the United Kingdom fou...
متن کاملGroundwater Fate of Aromatic Hydrocarbons at Industrial Sites: a Coal Tar Site Case Study
The fate of groundwater contaminants in anthropogenic fill materials was investigated at a coal tar site, Site YYZ. This site was representative of other contaminated sites with a history of industrialization at which wastes from process operations form the local subsurface solids. The solids composing the groundwater-bearing unit at Site YYZ were reactants (oil), byproducts (tar, coke) and was...
