Science g e t s α voice in nat ional policymaking as President Eisenhower appoints MIT president James R. Killian, Jr., to new post of Presidential science adviser. Scientists approve the move but wonder whether this is the answer to long range problems of U. S. science. Page 25.

F E A T U R E Magnesium's chemical and nonstructural uses are growing faster than the industry as a whole. At present over a third of primary production is going into chemical uses—tita­nium tetrachloride reduction and Grignard reagents. Page 72.

I N D U S T R Y & B U S I N E S S Pe t ro leum produc ts sales lag this yea r . Some declines are blamed on industrial production drop, but lack of gasoline consumption growth confounds the oil industry. Page 28. More of t he same—process firms indict high cos t s for erod­ing earnings so far this year. Some third-quarter reports take earnings for first nine months ahead of last year, but many others show drops. Page 30.

M A R K E T S Influenza, the Asian type and ordinary kinds, has people running to the corner drugstore for aspirin. Result: record aspirin production. Trend to aspirin for rheumatism and arthritis also ups output. Page 36.

M A N A G E M E N T Four factors wil l influence industrial relations of the future, says Labor Secretary Mitchell. Principal one: public insistence that labor and management conduct their busi­ness for public good. Page 39.

G O V E R N M E N T Slowdown in U. S. atomic power development may lie ahead unless we have a reactor system that can be ex­ploited on a large scale in 1963. AEC's solution: push develop­ment of water cooled and moderated reactors to meet the atomic power timetable. Page 42.

RESEARCH U. S. drug companies will spend 7 .5% of sales this year for research—$127 million in all. This is $17 million more than last year. Main objects of this research are new drugs, better drugs, and cheaper drugs. Page 48. Organic materials capable of withstanding 1000° F. for prolonged periods of time are goal of chemists working in the lubrication field. The high-temperature goal of 500° F. set two years ago for 1965 already has been met. Page 49.

P R O P U C T I O N "Packaged" reprocessing plants seem a likely a n s w e r to the question, "Where will spent power reactor fuels be processed?" Such a plant could get additional revenue from the recovery of radioactive isotopes. Page 50.

C H EM ICALS Two new silicone fluids—lubricants for the jet age—are stable to oxygen, perform at 700° F . General Electric designs new testing equipment to check silicones at higher tem­peratures than standard testers can take. Page 53.

EQUIPMENT Speedy turbine mixer emigrates from Europe, is licensed by Swedish inventor for U. S. manufacture. Al­though still under test, the unit shows good results in mixing concrete, looks promising for chemicals. Page 56.

Keeping Tabs on ACRYLONITRILE There are a great number of compounds, both organic and inorganic, possessing labile hydrogen atoms wh ich add readily to the carbon-carbon double bond of Acrylonitr i le. This reaction i s commonly known as "cyanoethy la t ion" .

The compounds that have been added to Acrylonitr i le to produce cyanoethyl derivatives may be classified according to the atom attached t o the reactive hy­drogen. Thus, examples of cyanoethyla­t ion of compounds conta in ing As-H, B-H, Br-H,C-H,CI-H, N-Η,Ο-Η, P-H,S-H, Si-H, and Sn-H have been reported. Among the specif ic classes of compounds that

undergo cyanoethylation are a var iety of amines, amides, alcohols, mercaptans, aldehydes, ketones, esters, inorganic acids and their salts.

The cyanoethylation reaction usually requires an alkaline medium (about pH 11-13). However, some aromatic and heterocyclic amines require an acidic catalyst such as acetic acid.

Synthesis problems? Cyanoethylat ion may offer an economical route to profit­able new products. Your nearest Cyan-amid Petrochemicals representative wil l be glad to show you the way.

EDU CAT ι ON High schools short on science teachers will wel­come a new series of films made at the University of Florida. These sound-and-color films, to be available next year, make up an entire course in high school chemistry. Page 88. Business can still place college graduates with no trouble. Annual survey shows that only 66% of the technical openings and 80% of the nontechnical were filled this year. Page 90. Only α fifth of U. S. graduate students have enrolled in the physical sciences, NSF survey shows. Chemistry brightens the picture, however, by making the best showing. Page 90.

ACS N E W S Ten years of chemical progress are assembled in Chemical Abstracts Fifth Decennial Index, coming out over the next four years. Formula and numerical patent indexes sup­plement author and subject entries in this 19-volume decen­nial. Page 10O.

A N I L I N E a growing intermediate

for your industry An old-timer, true—but even in these days of innumerable multipurpose intermediates, aniline finds growing use as an economical s tart ing point in the manufacture of:

• Rubber Chemicals • Dye Intermediates • Explosives • Pigments • Pharmaceuticals • Photochemicals • Selective Solvents

Now, complete physical properties of aniline are presented in Cyanamid's new eight-page data book. Particu­larly interesting to those using aniline is the detailed section on "Analytical Test Methods. "
