Aluminium hydride

INTRODUCTION: All information here is to be used at your own risk. The procedures documented in this file, if carried out by unlicensed individuals would violate laws against controlled substances in most countries and could result in criminal charges being filed. If carried out by individuals unskilled at chemistry they could result in serious bodily harm. MDMA ("Ecstasy") is a semi-synthetic compound which can be made relatively easily from available precursors. Synthesis instructions exist which

Part 1: Esters aromas are very distinct and often pleasant, they are often used in food aroma and fragrances.1 Esters chemical properties are distinguished by their low molecular weight and low boiling points, caused by their dipole-dipole and dispersion interaction.2 Esters are the result of a condensation reaction, in which a carboxylic acid, an alcohol, and an acid catalyst react to create a water molecule and an ester. In this part of experiment, alcohol(2ml) and CH3COOH(1ml) will react to

to learn how to use sodium borohydride to reduce benzil to its secondary alcohol product via reduction reaction. This two-step reaction reduces aldehydes by hydrides to primary alcohols, and ketones to secondary alcohols. In order for the reaction to occur and to better control the stereochemistry and yield of the product, the metal hydride nucleophile of the reducing agents such as LiH, LiAlH4, or NaBH4 must be carefully chosen. Being that LiAlH4 and NaBH4 will not react with isolated carbon-carbon

Throughout the decades, women’s fashion has evolved many times, each time creating a fashion stamp unique to that particular decade. One thing has remained the same and managed to remain a part of every era: hairspray. It is a cosmetic product that is meant to hold hair in its place. A lot of products we use today are may have unseen consequences to daily usage. A product I use almost daily is hairspray. I always knew hairspray was bad for the environment because of the aerosol that was in them

Nickel Introduction 　　The intension of the paper is to analyse the commodity attractions of the element nickel. It is highly related to physical and chemical properties of the element because any commercial usage of this element is based on its property. Also, nickel is extracted from ore, so the ore deposit of it will be highly related to the capital of any nickel related business. The laterite nickel ore deposit, Greenvale located in Queensland be focused on to reveal the genesis and other attributes

an incredible range of materials to make cars, together with iron, aluminium, plastic steel, glass, rubber, rock oil product, copper, steel et al. These components square measure wont to produce everything from those little things we do not rely on, like dashboard needles and wiring, to the large stuff, like the cylinder block or the transmission gears. But besides this most common metals uses in automobile are steel and aluminium. These materials have evolved greatly over the decades, changing into

1) The sole plate of the steam iron: This is usually the metal thick, triangular-shaped slab of iron that forms the base over which the electric iron is built up. The sole plate is cast of molten aluminium. Some part of the mould has the holes shaped in it which creates the holes that are essential in a steam iron. Heated metal is inserted into a mould under pressure then cooled and then released. This cooled sole-plate is later on treated in several

Literature Review: History of the swamp boat: The first swamp boat, also known as an airboat or fanboat was built in 1905 in Canada by a team led by Alexander Graham Bell. The classic design of a swamp boat consists of a flat bottomed hull powered by an aircraft or car engine driving an aircraft propeller. They are a popular means for fishing, hunting and touring the environment in the southern states of America. Hull Design: The classic swamp boat design utilizes a flat bottom hull with an inclined

Reported incidences of toxicity due to aluminium based vaccines have always been a concern (Clements, 1996; Clements and Griffiths, 2002; Edleman, 1997). Therefore, there has always been a constant effort to search for alternative adjuvants. Polymeric micro and nanoparticles can act as a delivery vehicle and along with their adjuvanting capabilities may enhance the efficacy of the vaccine (Gregory et al., 2013; Koping-Hoggard et al., 2005; Panyam and Labhasetwar, 2003). Biodegradable polymeric nanoparticles

According to Pichtel (2005), unwanted materials in the recycled process can affect in a negative way the outcomes of the recycle process and can be hazardous to workers. In addition, some industries will not accept low levels of contamination and some other industries just remove foreign material. Contamination affects the quality and recyclability of products since unwanted materials can damage the products. Recycled Paper- According to Pichtel (2005), “Paper products comprise by far the majority
