Before the final assembling of the apparatus, the flasks are charged as follows One kilo of freshly fused and finely powdered acid potassium sulfate, 200 g. of powdered potassium sulfate, and 300 g. of dry glycerol (Note 3) are thoroughly mixed in each of flasks B and D. In each of flasks I and M is placed about i g. of hydroquinone to act as a stabilizer for the acrolein (Moureu, Compt. rend., 170, 26 (1920)). 

Satisfactory methods for the preparation of acrolein have been described by Wohl and Mylo,i Witzemann, andMoureu. In the Wohl and Mylo method the vapors of glycerol are passed over magnesium sulfate maintained at 330-340.° Witzemann s method involves the use of magnesium sulfate at elevated temperatures with the consequent danger of breaking the generating flasks. Moureu s method involves apparatus not always available. 

The procedure described is essentially that of Bandrowski 1 and Baeyer 2 as modified by Ruggli.3 The same general method has also been used by Backer and van der Zanden4 and by Moureu and Bongrand.6... 

It is used as an intermediate in the synthesis of various chemicals as a low-boiling solvent for gums, resins, NC, etc it is also considered a candidate for use in fuel-air munitions Refs 1) Beil 17,6, (4) [12] 2) H. Moureu... 

The early practical application of antioxidants was connected with the development of rubber production. The rubber is easily oxidized in air, and the first antioxidants were empirically found and used to stabilize it [1]. Empirical search for antioxidants was performed by Moureu and Dufresse [2] during the First World War. These researchers successfully solved the problem of acrolein stabilization by the addition of hydroquinone. They explained the retarding action of the antioxidant in the scope of peroxide conception of Bach and Engler (see Chapter 1). They proposed that the antioxidant rapidly reacts with the formed hypothetical moloxide and in such a way prevents the autoxidation of the substrate. 

This procedure is a modification of the method employed by Moureu and Mignonac,3 who first reported the preparation of ketimines via Grignard-nitrile complexes. The use of methanol... 

From 1924 to 1933, the editors of the Annales de Physique were Marcel Brillouin, Aime Cotton, and Jean Perrin and the editors of the Annales de Chimie were Charles Moureu, Georges Urbain, and Marcel Delepine.

Moureu investigated the addition of alcohols, catalyzed by sodium methoxide, to acetylenic esters and has shown that enol ethers are formed as primary adducts. It has been shown that compounds such as potassium cyanide, a mixture of mercuric oxide, boron trifluoride,... 

In his studies at the Ecole Sup rieure de Pharmacie in Paris, Charles Moureu made an outstanding record. In 1907 he became professor of pharmaceutical chemistry, and ten years later he accepted the chair of organic chemistry at the College de France as M. Berthelot s successor. 

Although most of his work was done in the fields of organic and theoretical chemistry, Moureu and his assistants also devoted much... 

In 1911 Moureu and Lepape found that, although the neon, argon, krypton, and xenon in natural gases are always present in a fixed proportion, the proportion of helium to the other gases (since helium is continually being created by disintegration of radioactive elements) varies within wide limits. 

Moureu and his collaborators, unfortunately, were never able to find any source of neon, argon, krypton, and xenon that would be easier to exploit than the atmosphere. M. Georges Claude however succeeded in tapping this difficult but limitless source of the rare gases and developed from it a wonderful new field of illumination (81, 83). 

Charles Moureu was editor of the Annales de chimie et de -physique and of the Revue scientifique. In spite of his many scientific honors and duties, he always maintained affectionate and sympathetic contacts with the humble workers with whom his childhood years had been spent. He died at Biarritz on June 13, 1929 ( 82).
