Lerner L. Small-Scale Synthesis of Laboratory Reagents with Reaction Modeling

Taylor and Francis Group, LLC, 2011. — 240 p.When working in a small chemical laboratory attached to a nonchemistry-speciɑc project, one is frequently asked to solve problems that are occurring with the main project. Usually, one can think of several solutions, and experimental testing is required to choose between the different approaches, or indeed to ɑnd an approach that works. These often require the use of small amounts of chemicals that the laboratory does not stock. Obtaining these chemicals from commercial suppliers in a suitable timeframe sometimes poses problems. This is particularly the case in isolated regions such as Australasia, when the supplier has no local stocks of hazardous substances and they have to be brought in from overseas, something which can introduce delays from several weeks to six months or more. Since there is no certainty that the substance whose acquisition is creating a delay will form part of the ultimate solution, this delay is particularly objectionable. The primary aim of this book, therefore, is to provide reliable laboratory syntheses of the most common
reagents whose acquisition can introduce delays due to their hazardous nature.P.S. Подробно освещены электролитические лабораторные методики получения щелочных металлов (натрия, калия, лития, цезия)!Safety in the Laboratory
