In announcing this purpose it may be well to mention at the outset some of the difficulties in the way of the research chemist which it is hoped this series will be able to overcome. The cost of chemicals is prohibitive to the majority of chemists this was true before the war when Kahlbaum s complete supply was available and to-day with our dependence on domestic stocks this cost has increased. The delay in obtaining chemicals especially from abroad even if the expense need not be considered is an important factor. These difficulties have therefore thrown the research chemist on his own resources. The preparation of materials for research always time consuming and annoying is made increasingly so by the inexactness of the published information which so often omits essential details. Because of this much needless experimentation is necessary in order to obtain the results given in the published reports. As the additional information thus acquired is seldom published duplication of such experiments occurs again and again --a waste of time and material. It is hoped these difficulties may be remedied by the publication of this series of pamphlets. In other words the authors hope to make this a clearing house for the exchange of information as to methods of preparation of some of the .

• experiments are elaborated using small scale glassware and equipments from a Small Lab Kit
• developed at the Department of Chemistry
• Faculty of Science
• Chulalongkorn University in Thailand
• This Small Lab Kit was created as a result of the research project entitled “Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” sponsored by Thai Research Fund (RDG 3 07 2543)
• One of the outcomes of this project is the organic laboratory book entitled “Organic Chemistry Laboratory Based on Chemical Safety and Pollution Minimization” written in Thai by professors from 7 universities in this project
• They compiled
• adjusted and tested the experiments taken from several traditional organic chemistry laboratory books using the prototype of Small Lab Kit
• Currently
• some selected experiments from this Thai organic chemistry laboratory text have further been modified
