Catalyst for methanation of CO
146 Res.Dev., zo~lg8i)6~5~. In a very recent paper by A. Baiker, W. Caprez and W.L. Holstein (IEC, Prod.Res.Dev., 22(1983) 217; see also Chem.Tech., (1983),'593), the mechanism of the reaction over CufA1907) was elucidated. Tracer studies showkdYthat the rate determining step in the reaction involved the abstraction of an ~-hydrogen atom from the alcohol. This step is followed by the addition of the amine at the cw-position and then by the replacement of the OH group by hydrogen. The by-products obtained during the reaction may also be explained by the scheme which is perfectly general and can be used to describe the reactions of a~onia or of primary or secondary amines with primary or secondary alcohols, aldehydes or ketones. We are pleased to be able to report that Alfons Baiker, one of the authors of these papers,has agreed to become a regular correspondent for News Brief.
_Catalyst for ~ethanation
of CO
H. Takaya et al. (Agency of Industrial Sciences and Technology, Japan, Jpn. Kokai Tokkyo Koho, 58-10740, 1983) have reported that alloy-type iron and nickel catalysts (Fe-Ni-Mg Al 04) for methane synthesis from CO and fi2 could be prepared by adding a powder of the oxides of Al and Mg to an aqueous solution containing iron and nickel nitrates followed by mixing, drying, calcination (500X, 5 h) and crushing. The catalyst was thermally stable and had good resistance to deactivation. Oxalic Acid Esters H. Miyamori et al. (Mitsubishi Gas Chemical., Inc., Japanese Patent, Kokai Tokkyo Koho, 58-109446, 1983) have reported that oxalic acid esters

could be prepared by autoc?aving and heatinq aliahatic alcohols., CO and molecular 02 in the presence of Pd, heteropoly acid compounds and nitrogen compounds. For example, a mixture of n-butanol (40 ml), palladuim sulphate (15 mg), 12 molybdosilicate
at 800C to give 11.38 m mol of (C02B1.112 with 94.4% selecti it and a production rate of 2.6 mol l-rh-Y. The E.V. Murphree
Award
The Editors of Applied Catalysis would like, belatedly, to congratulate Dr. Bob Grasselli. a member of the Editorial Board, on the award of the E.V. Murphree Award in Industrial and Engineering Chemistry, sponsored by Exxon Research and Engineering Chemistry (See Chem.Eng.News, August 29, (1983) p.42). Grasselli, who has worked with Standard Oil Company (Ohio) for all his professional life, was born in Galje, Yugoslavia and, after study at the University of Graz, Austria, received his A.B. from Harvard (in 1952) and his MS (in i955) and PhD (in 1959) from Case Western Reserve University. He is now Science Fellow at Sohio, the highest technical rank in this organisation. The award to Grasselli, was Made in recognition of his contributions to the theory and commercial practice of allylic oxidation and ammoxidation over heterogenous catalysts. He played a ma'jor role in the discovery of the Sohio one-step acrylonitrile process and in the development and commercialisation of a series of catalysts for the production of acrylonitrile and acrylic acid. He was deeply involved, for example, in the develo~ent of the first commercial uranium-antimony oxidation system and later of the complex antimonate and bismuth molybdate systems currently used in some 23 countries throughout the world.
