Experimental details for preparation

A selection of methods taken from the original literature with experimental details for preparation of polychloroalkanes is collected in this Appendix. Methods are organized in order of increasing number of carbon atoms and then in order of increasing number of chlorine atoms. The original language is preserved. A complete list of syntheses is given in Table 2. 

Primary research journals are the ultimate source of most of the information in chemistry. These journals publish original research results in several formats. Articles are full papers that provide historical discussions together with a presentation of the important findings, conclusions, and experimental details for preparing new compounds. Communications and letters are short articles, sometimes with brief experimental details, that are restricted to a single topic or important...

Inorganic Syntheses (McGraw-Hill, New York). A series which contains experimental details for preparation of inorganic compounds, including some organometallic derivatives. 

The ethereal extracts are then united, dried with a suitable drying agent and filtered. The filtrate is then cautiously distilled, the ether being first distilled and finally the organic compound if volatile if the compound is solid, the crude residue is purified by recrystallisation. Very great care must be taken on all occasions when ether is distilled because of the risk of fire or of an explosion full experimental details for this operation are given, both on p. 8o (Preparation of Ether) and on p. 164 (Pre-... 

In order to obtain practice in the preparation of the above derivatives, experimental details for a few typical examples will be given. 

Experimental details for the preparation of oximes, phenylhydrazones and p-nitrophenylhydrazones will be found under Aromatic Aldehydes, Section IV,135,4-6. 

Experimental details for the preparation of derivatives with benzoyl chloride and with 3-nitrophthalic anhydride are given in Section IV,100,2 and 7. 

The foUowing are typical experimental details for the preparation of naphthalene picrate. Dissolve 0 -1 g. of naphthalene and 0-2 g. of picric acid separately in the minimum volume of hot rectified spirit (about 2 ml.), mix the solutions and allow to cool. FUter and wash with 2 ml. of alcohol. RecrystaUise from hot alcohol, ethyl acetate or ether. 

Nitro derivatives. No general experimental details for the preparation of nitro derivatives can be given, as the ease of nitration and the product formed frequently depend upon the exact experimental conditions. Moreover, some organic compounds react violently so that nitrations should always be conducted on a small scale. The derivatives already described are usually more satisfactory for this reason the nitro derivatives have been omitted from Table IV,9. 

The procedures for the preparation of a number of azo dyestuffs are described in Sections IV, 76-1V,82 these include the indicators methyl orange and methyl red. Experimental details for the preparation of other typical dyestuffs and indicators are given in the following pages. 

Procedure B. The experimental details for the preparation of the initial solution are similar to those given under Procedure A. Titrate 25 or 50 mL of the cold solution with standard 0.1M hydrochloric acid and methyl orange, methyl orange-indigo carmine, or bromophenol blue as indicator. Titrate another 25 or 50 mL of the cold solution, diluted with an equal volume of water, slowly with the standard acid using phenolphthalein or, better, the thymol-blue cresol red mixed indicator in the latter case, the colour at the end point is rose. Calculate the result as described in the Discussion above. 

Experimental details for the preparation of l-acyl-2-re77-butyl-3-methyl-4-imidazolidinones are given below. 

Small scale preparations, experimental details for aniline, 1102 cinnamic acid, 1113 Soaps, 445... 

The following are typical experimental details for the preparation of naphthalene picrate. Dissolve 0.1 g of naphthalene in the minimum of hot ethanol and add to 1 ml of a saturated solution of picric acid in ethanol. Warm the mixture and then cool to allow the product to crystallise. 

Wheeler, T.S. (1963). Organic synthesis, Coll. Vol. IV, 479 (experimental details for the preparation of flavone). 

Bifunctional molecules which favor bimolecular combinations have been widely used, with many variations in experimental details, for the preparation of fused ring systems. The electrophile can be either a reagent or preformed ring component. 

Benzo[l,2-c 3,4-c 5,6-c"]tritellurophene might have been prepared by dehydrogenation of the product obtained in the reaction between hexakis[bromomethyl]benzene and lithium telluride3. Experimental details for the preparation of these compounds were not reported.
