It melts at '0. In announcing this purpose it may be well Organic syntheses book 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. It is then mixed with a mush of 2. Since a small amount of nitrotoluene is volatilized, it is advisable to carry on this work under a hood. The use of a capillary tube for the addition of sodium nitrite prevents loss of nitrous acid by local reaction at the surface of the acid solution.

Finely powdered sodium carbonate is then added in g. For this reason, a low-yield step along the way can mean practical failure Organic syntheses book the overall sequence. Other Methods of Preparation Quinone may be prepared by the oxidation of aniline with dichromate or manganese dioxide and sulfuric acid. The wide variation in yields which are mentioned in the experimental part is probably due to a slight change in the grade of the chemicals which are used in this preparation.

Only after exact duplication of the results in both laboratories are the directions considered ready for publication Finely Organic syntheses book sodium carbonate is then added in g. Other Methods of Preparation Toluenesulfinic acid and its salts have been prepared by three general methods: 1 The reduction of the sulfonyl chloride. It is nevertheless necessary to allow the reaction mixture to stand a long time; if the product be filtered off after only twenty-four hours, a further quantity of dye will separate from the filtrate on standing.

It has been stated[2] that this process does not work satisfactorily and yields a different product, of brownish-red color. Technique of organic Organic syntheses book Weissberger QD If it is heated any hotter, bumping takes place. In this process, l. The yield of this fraction varies in different runs from to g.

The solid is sucked as dry as possible, spread out on a tray in order to allow most of the water to evaporate fifteen to twenty hours and then suspended in 4 l.

As much water as possible is pressed out of the crystals. Occasionally it must be free even from traces of the ortho compound, and in this case should be crystallized again from 80 per cent alcohol; it then melts at '0.

Under these conditions, the yield of product is much lower.

News Notes Although these directions have been used many times with results exactly as described, in a few cases the yields have dropped to per cent without any apparent reason.

The cake of unchanged zinc dust and zinc compounds is transferred to a 3-l. Because of this, much needless experimentation is necessary in order to obtain the results given in the Organic syntheses book reports.

Exceptions arise when the desired product is obtained as a component Organic syntheses book a mixture that is difficult to separate.

News 66, H37 Reference Section. Notes The free sulfinic acid may be prepared by dissolving the sodium salt in cold water and carefully acidifying the solution with hydrochloric acid.

UntilOrganic Syntheses was published only as an annual printed volume. Benjamin, Inc. By then, chemists from other universities and industry were also contributing. The contents of the flask are well mixed and the mixture heated gently over a free flame.

Any solid material sticking to the walls of the vessel is now washed down into the liquid with the remainder of the acid, the flask is attached to a reflux condenser, then set, without shaking, over a cm. The product should possess only a light-lemon color.Organic Syntheses Based on Named Reactions, Fourth Edition is an indispensable reference companion for chemistry students and researchers.

The book provides an overview of name reactions based on reaction types and products formed and presents schemes, procedures and references in a simple, one-page format that offers a brief, representative procedure for each name reaction.
