Название: Practical organic chemistry
Авторы: Mann F., Saunders B.
This work is based largely on the authors' experience with the teaching of practical organic chemistry to very large classes of students at Cambridge University. For such classes experimental directions involving the utmost economy in chemicals and apparatus, and also in the students' time, are obviously required. Therefore the whole of the experimental work described in this book has been repeatedly checked by the authors themselves (and for the most part by their classes also) in order to obtain the desired results with a minimum expenditure of materials and time. In the section on Organic Preparations in particular, this detailed investigation of each preparation has frequently enabled unexpected simplifications and economies to be introduced, more particularly as many text-books still contain experimental directions which have frequently remained unchanged since their
original publication in chemical journals many years ago, and in which, moreover, occasional errors both in fact and in transcription have thus remained uncorrected. It is almost universally
found that departments of organic chemistry are more costly to maintain than other science departments, primarily because of the heavy consumption of organic reagents and solvents,
and the economies which have now been effected will, we think, be appreciated by most teachers of practical organic chemistry.
