AIR POLLUTION The major pollution caused by factories or industrials’ activities is air pollution. According to the Engineers’ Joint Council “Air Pollution and Its Control”‚ air pollution means the presence in the outdoor atmosphere of one or more contaminants‚ such as dust‚ fumes‚ gas‚ mist‚ odour‚ smoke or vapour in quantities of characteristics and of duration‚ such as to be injurious to human‚ plant or animal life or to property or which unreasonably interfaces with the comfortable enjoyment

A process for the preparation of racemic phenylethylamine which comprises contacting an optical antipode therefore‚ e.g.‚ L(-) or D(+)-1-phenylethylamine with sodium amide or sodium hydride. Claim: What is claimed is: 1. A process for preparing racemic 1-phenylethylamine which comprises contacting L(-)-1-phenylethylamine or D(+)-1-phenylethylamine with 0.01 to 1 weight percent‚ based on theamount of said phenylethylamine‚ of sodium amide or sodium hydride at a temperature of 70.degree. to 150

structures called functional groups‚ which can be distinguished by biochemical tests‚ such as Benedict’s Iodine‚ and Sudan III/IV. The Benedict’s test identifies reducing sugars (monosaccharide’s and some disaccharides)‚ which have free ketone or aldehyde functional groups). The groups reduce CuSO4‚ a component of Benedicts‚ resulting in a color change in the benedicts solution from a turquoise to a brick to rusty-brown color. Another class of carbohydrates called starches‚ a polysaccharide‚ can

the Benedicts test if the substance turns from a blue liquid to a greenish to yellow/orange/red shows the presence of a reducing sugar. BENEDICT’S TEST Introduction: Monosaccharaides and disaccharides can be detected because of their free aldehyde groups‚ thus‚ testing positive for the Benedict’s test. Such

Factors affecting seed and seedling vigour Seed vigour is a term encompassing the sum total of those properties of the seed that determine the potential performance of the seed or seed lot during germination and seedling emergence (Perry‚ 1978). Rapid and uniform germination are among the properties of vigorous seeds (Argerish & Bradford‚ 1989). Low vigour adversely affects such factors as optimal emergence‚ stress resistance and uniform growth of emergent seedlings (Patrick et al‚ 2000) and is

low viscosity and high solids content. Properties The physical and chemical properties of MEK are determined largely by its carbonyl group. MEK engages in reactions typical of saturated aliphatic ketones. These include condensations with amines‚ aldehydes and many other organic compounds‚ hydrolysis (catalysed with acid or base)‚ oxidation via concentrated oxidizing acids or acidic peroxides‚ and reduction with hydrogen and metal catalysts. None of these reactions is likely to be important in nature

Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double
