T h e program will be centered around discussions in confer ence groutps. Participants are invited to bring demonstration and other special equipment. Formal lectures •will feature outstanding college and secondary teachers a n d will center around acHvances in inorganic chemis try, organtic chemistry, nuclear chem istry, and. science education. Field trips to rriodern industrial plants have been a r r a n g e d , also a visit t o the radia tion laboratories o f Vanderbilt Univer sity. A n o t h e r special event will be a panel discussion a t P e a b o d y Teachers College o n Education of a Science Teacher.

Housing aTid board will be $40 per per-* son. FuQ scholarships are available from t h e F u n d for the Advancement of Education of the university. North Central Session of the work shops, w h i c h is t r i e Second Chemistry Institute for College Chemistry Teach ers, h a s a s its a i m t h e teaching of modern tHeories a n d practices in the various fields of criemistry, a n d t h e de veloping o f such material i n the best possible manner for its incorporation into t h e college chemistry curricula. A continuous series of lectures will be presented in general and inorganic chemistry over trie five weeks. Staff will b e selected from t h e departments of chemistary, cliernical engineering, and physics at Minnesota, also, well known chemists im the educational and indus trial fields will be invited t o give lec tures. Members of t h e institute staff will lead discussion sessions, and regis trants will establish panel groups, round-tabl^ discussions, and seminars for airing nnutual p r o b l e m s a n d method ology. 2424
Director of t h e institute is Robert C . Brasted, associate professor of chem istry, University of Minnesota. Tui tion fee for t h e institute, which will function as part of the summer session program of the university, is $ 5 9 . G r a d u a t e credit equivalent to five quar t e r hours will be a w a r d e d to those w h o desire it. Dormitory accommodations will be available t o all attending. Al though the dormitories cannot accom m o d a t e children, rooming facilities suitable for families a r e available n e a r t h e campus. Eastern Session. T h e m e of the Sec o n d Chemistry Institute at Syracuse will be Research Frontiers in Chemistry. I t was organized to provide teachers of chemistry in the smaller colleges a n d universities an opportunity to study modern chemistry under chemists of
the caliber usually found only in r e search centers. F o r m a l and informal group discussions on teaching p r o b l e m s will be featured, a n d o n the impact of lew concepts and knowledge on trie teaching of t h e standard undergraduate courses in chemistry. Visits to nearby chemical industries will b e arranged. O p p o r t u n i t y will also b e afforded t o observe important research in process at Syracuse Uni versity and a t units of the S t a t e Uni versity of N e w York at Syracuse. O c casional evening lectures on related fields of science will be presented, also scientific and industrial movies. T h e r e will be an exhibit of textbooks.

SAMPLES AVAILABLE OF NEW PIPERAZINES AND PYRAZINES
Recently, we announced the development of methods for the commercial manufacture of important piperazines and p y r a z i n e s — specifically 2-methylpiperazine ; cis—2,5-dimethylpiperazine ; trans-2,5-dimethylpiperazine ; mixed cis-trans-2»5-dimethylpiperazine ; 2-methylpyrazine ; 2,5-dimethylpyrazine. Now we are happy to state that samples of these products are available upon request·
SOME SUGGESTED USES FOR PIPERAZINES AND PYRAZINES
For polymers : Vinylpyrazine can be prepared from 2-methylpyrazine and formaldehyde and can be polymerized in the same manner as 2-vinylpyridine . . * polyamides are formed by reacting piperazines with various dicarboxylic acids. For pharmaceuticals ; Antiviral activity is reported for sulfa drugs derived from pyrazine while pyrazine carboxylic acids have antipellagric activity and can be prepared from the corresponding methyl pyrazine s by oxidation . . . antihistaminic activity is reported for the 1,4-di-subst itut ed piperazines . . . piperazine. derivatives, especially the salts of organic acids, are particularly effective as anthelmintics. Pyrazine and its homologues have, to date, found use almost wholly in the pharmaceutical field. However, due to similarities in structure and reactions, the pyrazines will probably find applications in fields where the pyridines are presently used. Piperazines, aside from use in pharmaceuticals and for forming polymers, have potential applications in: surface-active agents, stabilizing agents, agricultural chemicals, rubber chemicals, catalysts, solvents, To aid you in your research, we've compiled a 33-page booklet containing excerpts from chemical literature. These excerpts relate to the reactions and applications of piperazines and pyrazines and their derivatives. Copies of this survey are available without charge · . . simply write us on your company letterhead.
