Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to

Rinse with 5 mL of 1:1 mixture of water and glacial acetic acid to complete the transfer of phenylhydrazine. When a yellow solid emerges‚ swirl the mixture. Wrap a dry cloth around the flask. Cool to room temperature (preferably overnight). Filter off osazone. Press and drain it. Wash with a cold mixture of 10 mL each of water and ethanol. No need to dry the product for the

The Government is actively attempting to shift the emphasis of municipal waste management further up its hierarchy of waste options‚ so that the industry’s dependence upon an ever diminishing landfill resource is reduced. In the wake of recycling targets‚ recycling credits‚ minimisation trials and general waste related policy and legislation‚ the Government

According to a report by MOEF (Ministry of Environment and Forests)‚ e-waste from old computers and mobile phones would jump by 500% and 1800% as compared to 2007 levels by 2020 in India. But before that‚ let us understand what exactly e-waste is‚ what are its implications and how companies are trying to curb this by using Green IT. Scenario of e-waste in India: Electronic waste (E-waste) in simple terms‚ refer to the discarded electronic devices. E-waste includes waste generated

There are only five platonic solids and the name of each shape comes from the number of faces it has.The five platonic solids are tetrahedron‚ octahedron‚ cube‚ icosahedron‚ and dodecahedron. Each solid is made of regular polygons and the polygons of each solid are congruent. The topics that will be discussed in this paper are what are the five platonic solids‚ who classified the five shapes‚ their key features‚ the shapes similarities and differences‚ and examples in real life.

Historical Research on Waste Management Sean Depkin Jones International University Abstract Waste management is a necessary industry and has been traced back to 3000 B.C. It originally started off garbage dumps or landfills and has progressed to recycling facilities and incinerators that produce both heat and energy from the burned waste. It has been influenced by both motorized transportation and the advances in technology. The most influential person in the waste management industry in the

Why Americans Lead the World in Food Waste‚ he claims that an estimated $160 billion worth of produce is wasted annually. Wasted food is one of the largest arising problems within America today‚ and the numbers for waste keep increasing year by year. Solutions have been thought out to help solve this drastic problem‚ but nothing will be accomplished until society open their eyes and see what is truly happening. The biggest question that arises about food waste is what causes this? There are a lot

We recycle more waste from our worldwide facilities than any other automaker‚ and no other automaker has as many facilities contributing zero waste to landfill. Whether it’s one of our 85 landfill-free manufacturing facilities‚ 20 landfill-free non-manufacturing facilities or one of the many that are nearly there‚ every site is serious about finding ways to reduce and reuse waste. In doing so‚ we reduce our impact while encouraging
