Toluene

Introduction In 1950 the Nobel Prize for Chemistry was awarded to Otto Diels and Kurt Alder for their description of an invaluable chemical reaction (The Nobel Prize in Chemistry 1950). The reaction they described was for the formation of carbon-carbon bonds in a six membered ring with exceptional control of its stereochemistry in one step (Diels-Alder Reaction Gains Nobel Prize). This was an important discovery due to the fact that six membered rings are abundant natural products and man-made…

distinct smell, thus concluding that the compound is ionic. The solubility tests indicated that the compound was soluble in water, NaOH, and HCl and non-soluble in acetone and toluene as shown in Table 1. The compound was soluble in water indicating that the compound is either polar or ionic, but not soluble in toluene or acetone eliminating it being polar or nonpolar, making our compound ionic. The compound was also soluble in both NaOH and HCl, which are contradicting because a compound…

INTRODUCTION The Love Canal episode is one of the major and most publicized environmental disaster recorded in America history. In recent time, it has been described as an epidemic. It became a focus of intensive and extensive studies on health effect, environmental studies and epidemiologic research (Friis and Seller, 2014, p.20; Jasanoff, 1998 p.83). This paper attempts to bring to light how a community is forced to bear the consequences of decision made by greedy and negligent corporate…

We were further interested to elaborate our catalytic conditions to the Friedel-Crafts reaction of indoles with α-amido sulfone 8 as a precursor of N-Boc α-imino ethyl glyoxylate. The use of imino derivatives of glyoxylates as electrophiles in aza-Friedel–Crafts reaction afforded the corresponding 3-indolyl glycine derivatives, an important class of nonproteinogenic amino acids useful for synthetic intermediates and building blocks for natural products such as dragmacidins.[14] Although some…

The employees in Vietnam were being exposed to a toxic adhesive named toluene. Toluene has been found to cause harmful effects among workers who are not properly guarded from the poison and the fume that it emits. The laws protecting the workers are ignored in favour of cutting costs and lowering health standards. This is possible…

In this lab, two methods of distillation (simple and fractional) were utilized to separate a mixture of volatile compounds (cyclohexane and toluene). As a first observation of the results and data generated, looking specifically at the simple and fractional distillation curves, it seemed that the fractional curve obtained was not as expected. In fact, it was not very different from the simple distillation curve, having a gradual positive slope. This means that there was actually not a big…

These are the household items that anyone can purchase. Industrial chemicals such as chloroform, toluene, benzene, methanol, coolants, paints, glues, and gases. These are the most dangerous, even to a first-time user. The general method of consuming solvents is called “huffing”. Initially, blood levels peak, dizziness, disorientation, light-headedness…

Since 2013, there was a wide variability in e-cigarette product engineering, including: nicotine concentrations in e-liquids, variable volumes of e-liquids in the product, different carrier compounds (propylene glycol with or without glycerin), different additives, flavors, and battery voltage. Instead of burning tobacco in conventional cigarette to release smoke that contains nicotine, users of e-cigarettes will heat a nicotine liquid and convert the liquid to a vapor then inhale it. Depending…

The movement to erase industrial sodium fluoride from all things related to the world’s water supply was starting to grow at a few years ago, and now is still growing faster along with coming evidences against the fluoride. A report published by The Lancet classified the fluoride as a neurotoxin, in the same group of mercury, arsenic, and lead. For your info, The Lancet is the oldest and most prestigious medical journal in the world. The news was first broadcasted by Stefan Smyle, the author,…

also happens from the chemical used in artificial nails.”The usage of Methyl methacrylate has been outlawed, Ethyl methacrylate is continued to be used for artificial nails, Nail salon workers also face exposures to other chemicals used, such as Toluene, Dibutyl phthalate, and formaldehyde when they are doing artificial nails for clients.” Are there any ways to prevent the damages?If so how?You can prevent damage by wearing the generic ones from the store.If you do your own acrylics you can…
