While much of traditional chemistry teaching centers on multi-gramme preparations, milligrammes of substances are sufficient for microscale chemistry. In universities, modern and expensive lab glassware is used and modern methods for detection and characterization of the produced substances are very common. In schools and in many countries of the Southern hemisphere, small-scale working takes place with low-cost and even no-cost material.

A manual that derives many experiments and procedures from the classic Feiser lab text, giving it an unsurpassed reputation for solid, authoritative content. It includes experiments that stress greener chemistry. Read more Please choose whether or not you want other users to be able to see on your profile that this library is a favorite of yours.

Macroscale and microscale organic experiments

While much of traditional chemistry teaching centers on multi-gramme preparations, milligrammes of substances are sufficient for microscale chemistry. In universities, modern and expensive lab glassware is used and modern methods for detection and characterization of the produced substances are very common.

In schools and in many countries of the Southern hemisphere, small-scale working takes place with low-cost and even no-cost material. There has always been a place for small-scale working in qualitative analysis, but the new developments can encompass much of chemistry a student is likely to meet.

There are two main strands of the modern approach. One is based on the idea that many of the experiments associated with general chemistry acids and bases, oxidation and reduction, electrochemistry, etc. Pioneering development in this area was carried out by Egerton C. Grey , [1] Mahmoud K. A further application of these ideas was the devising by Bradley of the Radmaste kits [4] in South Africa, designed to make effective chemical experiments possible in developing countries in schools that lack the technical services electricity, running water taken for granted in many places.

The other strand is the introduction of this approach into synthetic work, mainly in organic chemistry. Here the crucial breakthrough was achieved by Mayo, Pike and Butcher [5] and by Williamson [6] who demonstrated that inexperienced students were able to carry out organic syntheses on a few tens of milligrams, a skill previously thought to require years of training and experience.

These approaches were accompanied by the introduction of some specialised equipment, which was subsequently simplified by Breuer without great loss of versatility. There is a great deal of published material available to help in the introduction of such a scheme, providing advice on choice of equipment, techniques and preparative experiments and the flow of such material is continuing through a column in the Journal of Chemical Education called 'The Microscale Laboratory' that has been running for many years.

Scaling down experiments, when combined with modern projection technology, opened up the possibility of carrying out lecture demonstrations of the most hazardous kind in total safety. It has become a major presence on the educational scene in the US, it is used to a lesser extent in the UK and it is used in many countries in institutions with staff who are enthusiastic about it.

Macroscale and Microscale Organic Experiments 7th Edition – PDF – EBook

Laboratory Safety, Courtesy, and Waste Disposal Although microscale experimentation greatly reduces dangers from fire, explosion, and exposure to toxic, carcinogenic, teratogenic, poisonous, and corrosive substances, there are still hazards with which to contend in the organic laboratory. Even on a microscale, eye safety is a prime concern. Students must be required to wear safety goggles chemical splash goggles at all times, and the use of contact lenses in the laboratory should be forbidden. The instructor should read this chapter carefully, noting where local practices differ from the recommendations made in the text, for example how to dispose of a drying agent wet with solvent. These differences should be pointed out to the students, who should then read this chapter and be prepared to answer questions about it.

The size of the hook seems formidable, but the number of pages is really not very much different from other new introductory texts. At the end of each chapter is a.
