Trimethyl-hexamethylene diisocyanate is an aliphatic diisocyanate. It occurs as an isomeric mixture of the 2,2,4- and 2,4,4trimethyl-hexamethylene diisocyanate (about 1:1). It is a lowviscosity, colorless to slightly yellowish liquid with a weak, but specific odor. For more information contact: HULS AMERICA INC. P.O.

Several changes in ACS staff positions Several members of the American Chemical Society headquarters staff in Washington, D.C., have been appointed to new positions recently, and some newly created positions have been filled. Justin W. Collat, who formerly headed the Membership Division, has been named secretary-designate and will become secretary of the society upon Rodney N. Hader's retirement later this year. Halley A. Merrell will continue in his role as assistant secretary and will assume the additional title of assistant to the president of the society. D. H. Michael Bowen, formerly the director of the Books & Journals Division, will succeed Collat as director of the Membership Division, the activities of which have been expanded to include those of the Government Relations & Science Policy Department and the International Activities Department—both formerly components of the Public Policy & Communication group. That group had been headed by R. Eric Leber, who recently was appointed to represent the society in a special project to establish a science exhibit at the Smithsonian Institution (C&EN, March 28, page 34). The two remaining units of the Public Policy & Communication group—the Department of Public Communication and the Office of Corporation Associates—will be headed by a new director of public relations, Patrick P. McCurdy, who most recently was editor in chief for Chemical Week and is a former editor of C&EN. In the Membership Division, a Department of Member & Professional Services has been created, incorporating programs heretofore administered by the departments of Membership Activities and of Professional Services. The new department will be headed by Pamela Ayre, formerly manager of the Office of Local Section Activities. Earl Klinefelter, who formerly headed the Department of Membership Activities, and Robert K. Neuman, who headed the Department of Professional Services, both have been appointed special assistants in those areas on Bowen's staff.
Robert H. Marks, formerly director of publishing for the American Institute of Physics, has joined the ACS staff as director of the newly created Publications Division. The division comprises the former Books & Journals Division as well as Chemical & Engineering News. In the Publications Division, Randall E. Wedin, formerly a special assistant to the executive director and recently coordinator of National Chemistry Day, has been appointed head of the newly created Special Publications Department. In that position, Wedin is responsible for management of staff functions for Analytical Chemistry, Chemcyclopedia, CHEMTECH, Environmental Science & Technology, and Today's Chemist, the society's new controlledcirculation magazine. In addition, C. Michael Phillippe, formerly head of the Production Department, has been appointed director of Operational Support, which has been reorganized to encompass several staff support groups, including management services, office and information systems, production, and purchasing and travel. •
Updated guide to small chemical businesses An updated guide to small chemical businesses is now available, listing 331 companies, their addresses, phone numbers, key persons, major product lines, and services. Published by the ACS Division of Small Chemical Businesses, it includes a directory section with 164 headings, showing the firms offering each item or category. Consulting services are in a separate directory with 77 headings. This guide is the successor of "Directory for Trade and Information/' published by the division in 1984. Copies can be ordered from: DSchB Guide, Box 14373, Columbus, Ohio 43214. Price is $5.00 postpaid. Single copies will be sold at the exposition (booth 916) at the Toronto meeting for $4.00 U.S. or $5.00 Canadian. •
