tailieunhanh - EXPERIMENTAL ORGANIC CHEMISTRY

A study to measure indoor concentrations and emission rates of volatile organic compounds (VOCs), including formaldehyde, was conducted in a new, unoccupied manufactured house installed at the National Institute of Standards and Technology (NIST) campus. The house was instrumented to continuously monitor indoor temperature and relative humidity, heating and air conditioning system operation, and outdoor weather. It also was equipped with an automated tracer gas injection and detection system to estimate air change rates every 2 h. Another automated system measured indoor concentrations of total VOCs with a flame ionization detector every 30 min. Active samples. | E E E RIMENIAL E ORGANIC CHEMISTRY BY JAMES F.

PREFACE TO THE SECOND EDITION The appearance of the second edition of the author s Textbook of Organic Chemistry made it advisable to prepare a revision of this laboratory guide in order that the references given to the text should refer to the new edition of the latter. Advantage has been taken of the opportunity to give improved directions for a number of experiments and to incorporate new material of importance. Some additions have been made to the chapter on laboratory methods and directions for a few new preparations have been given. These include the preparation of normal butyl chloride from the alcohol and aqueous hydrochloric acid of triphenylmethane directly from benzene carbon tetrachloride ether and aluminium chloride of an amylene from secondary amyl alcohol and of a secondary alcohol from pentene-2. The author will be glad to receive suggestions from teachers who use the book with their classes. JAMES F. NORRIS. CAMBRIDGE MASS. April .
