Commercial Chemical Development Association

We are the official depository for publications of the Chemical Market Research Association and the Commercial Chemical Development Association. Inasmuch as many of these meeting papers are not published in periodicals, the two sets of proceedings form a valuable and interesting addition to our library. An up-to-date author and subject index is maintained by the library, so the material is of practical service to chemical market readers and to members of industrial market research departments. 

Commercial Chemical Development Association. Meetings four times a year. Papers frequently published in Chemical and Engineering News. 

In an address before the Commercial Chemical Development Association in March 1967, Mr. Neidig said in part ... 

Finally, I discern one more trend of the chemical industry and of its research programs which shall have important influence on market development in the WTO s. The industry has become increasingly aware that many problems of our modem society not only may be solved by the use of chemical technology, but that there may well be attractive profits in such solutions. As pointed out by H. D. Doan, president of Dow, in a speech before the Commercial Chemical Development Association on October 28, 1966 ... 

CARLTON A. SEARS, JR. is Vice President, Virginia Chemicals, Inc., and President and Representative Director, Virchem Japan Ltd. He obtained his PhD in Chemistry from Notre Dame. Following employment with American Cyanamid, he joined Virginia Chemicals Inc. in 1961, where he carries on ertensive business activities in Japan, Mexico, and Europe. Dr. Sears is active in numerous business associations, and has served as President of the Commercial Chemical Development Association and Chairman of the ACS Division of Chemical Marketing and Economics. 

Work on the characterization of oil-field emulsions coupled with chemical characterization of commercially available demulsifier formulations has shown that physical processes (temperature, pumping, and dispersed water size distribution) can be at least as important as the chemical effects associated with demulsifiers themselves in determining demulsifier effectiveness [468,469].In fact, there are so many variables involved in industrial demulsification that, to a large degree, demulsifier selection and performance evaluation are still conducted using simple test procedures developed for use in the plant or field. These tests, usually bottle or centrifuge tests, can be good indicators of performance trends, and are usually carried out for selected suites of commercial demulsifier formulations. 

Solid-state C NMR techniques provide a powerful means by which to obtain information about the carbon structure of fossil fuel materials. Indeed, CP/MAS measurements have been applied to coals and oil shales almost from their inception around 1976. Solid-state NMR measurements are now made routinely in fossil Riel research, particularly in coal structure studies. For oil shales, solid-state NMR methods are particularly useful because the measurements can be made on raw shale, without the need to remove the mineral matter, which generally accounts for >85 wt% of the rock. However, because of the reduced emphasis in developing oil shale deposits commercially, applications of NMR in oil shale research are now not as common as in the past. Nevertheless, NMR measurements have provided valuable information about various aspects of oil shales. For example, the extent of aromatization of aliphatic carbon moieties during conversion can be obtained by combining solid- and liquid-state NMR measurements with mass balance data. Such information is difficult to obtain by other methods and provides insight into the chemical processes associated with fossil fuel conversion. 

Reliability of the electrical properties of silicone-based isotropic adhesives has been the major difficulty to overcome and has essentially prevented commercialization. Another problem associated with silicones is that the addition polymerization reaction of silicones must be carefully controlled to prevent cure inhibition from various common chemical contaminants such as amines and sulfides. Other concerns include low-molecular-weight silicone polymer migration onto wirebond pads and very high GTE. There has been some activity in the development of hybrid resins that contain silicone blocks as comonomer with epoxies such that the epoxy processing can be maintained with the added stress reduction property of the silicones [52]. 

PERFLUOROALKYLPYRIDINES New developments ia trifiuoromethylpyridine technology are associated with the commercialization of numerous crop-protection chemicals as herbicides, fungicides, and iasecticides (Table 15). Physical properties for representative trifiuoromethylpyridines are fisted ia Table 13. 

Xyloflning [Xylol refining] A process for isomerizing a petrochemical feedstock containing ethylbenzene and xylenes. The xylenes are mostly converted to the equilibrium mixture of xylenes the ethylbenzene is dealkylated to benzene and ethylene. This is a catalytic, vapor-phase process, operated at approximately 360°C. The catalyst (Encilite-1) is a ZSM-5-type zeolite in which some of the aluminum has been replaced by iron. The catalyst was developed in India in 1981, jointly by the National Chemical Laboratory and Associated Cement Companies. The process was piloted by Indian Petrochemicals Corporation in 1985 and commercialized by that company at Baroda in 1991.
